Reviewing the results of seven years' work on the comparative and experimental investigation of cancer, says the general superintendent in his report, one is struck by the difference between the nature of the problems before us seven years ago and of those now being considered, as well as by the freedom one feels in investigating the problems presented to-day, without the incubus of having to consider them from the standpoints of the many hypotheses now proved to be untenable. I do not think that too much is claimed by asserting that the arduous labour of the past seven years is gradually effecting, and in several respects has actually effected, a complete revolution in many aspects of the cancer problem. But it has done still more in opening up new vistas in biology. Seven years ago no one conceived it possible that portions of the mammalian organism could be kept growing for a period four times the length of life of the whole animal. But to-day the number of different kinds of tissues now being propagated separately make it theoretically possible that the majority of the tissues may be so grown and segregated. In other words, a living animal can be analysed into many of its living component tissues. The finer relations of various kinds of tissues to another have been revealed by the application of the new methods. The biological alterations which living mammalian cells may undergo suddenly, as well as gradually, under the influence of experimental conditions, can now be studied. These and many other achievements in the field of general biology are the most important practical fruits which have accrued from the experimental study of cancer, upon which they have only indirect bearings. Ultimately they are bound to be of far-reaching general biological importance, although to-day they are merely the weapons that have been forged to attack cancer. Their further development and their utilisation for the solution of purely biological problems will probably precede the solution of many of the problems surrounding the nature and

causes of cancer.

vey with the mainland of Spitsbergen across Foul Sound, thus joining up the work of H.S.H. the Prince of Monaco, the late Captain Guissez, Captain Bourée, and Captain Isachsen in the north-west of Spitsbergen.

In 1907, Dr. Bruce brought back geological collections which have been described by Dr. G. W. Lee, of H.M. Geological Survey of Scotland, in a paper read to the Royal Physical Society, Edinburgh. These rocks and fossils entirely change previous opinions of the geology of Prince Charles Foreland, which was thought to be Silurian, whereas the rocks of Prince Charles Foreland consist, first, of a series of metamorphic crystalline schists, quartzites, and non-fossiliferous shales and hard grey limestones; secondly, of the fossiliferous limestone, probably permo-Carboniferous; and, thirdly, of grey shales containing the remains of dicotyledonous plants of Tertiary age. This time Dr. Bruce will carry with him a specially strong geological staff, and he hopes to clear up definitely the whole geology of Prince Charles Foreland and the neighbouring coasts of the mainland.

A special study of the botany of the Foreland will be made, Dr. Rudmose Brown carrying on that special part of the work. one Dr. Bruce's staff consists of Mr. J. V. Burn Murdoch, who accompanied him to Prince Charles Foreland in 1907; Mr. John Mathieson, of H.M. Ordnance Survey of Scotland, who will take entire charge of the survey work; Dr. R. N. Rudmose Brown, late botanist of the Scotia, at present lecturer on geography, Sheffield University; Mr. Ernest A. Miller, who accompanied Dr. Bruce in 1906, and has since been attached to the meteorological and magnetical service of the Argentine Republic, having wintered at Scotia Bay, South Orkneys, during the last year. Mr. H. Hannay and Mr. A. M. Peach are the geologists, and Mr. Alastair Geddes will also accompany the expedition.

While some chance opportunity may yield results of immediate practical moment, the outlook on therapeutics in the meantime is in the direction of preventing dissemination or metastasis. The means of explaining why inoculated cancer can undergo spontaneous cure have been greatly enriched by the acquisition of fresh strains of propagable tumours behaving in a variety of ways in this respect, and presenting all gradations from some growing progressively in every animal inoculated, to others which, while developing for a time in every animal, are ultimately got rid of in all cases by the active resistance which the tumours induce against themselves.

In acknowledging a vote of thanks, the Prince of Wales said, during the course of his remarks:-" When presiding over this committee on previous occasions I have expressed the view that immediate results in regard to the cure of cancer must not be counted upon, but that rather we must look forward to steady and consistent progress in accordance with the experience of all scientific investigation. There can be no doubt, however, that the seven years' work already accomplished by the fund has brought about a complete change in the standpoints from which cancer should be studied. The many and varied lines of research are being pursued with the utmost perseverance, and every development, as it occurs, is followed up with the minutest care. During the past year an important work the third scientific report-has been issued from our laboratories, and has been received with appreciation by all those at home and abroad who are competent to express opinions on these highly technical researches. This of itself marks a steady and valuable advance, and one of which we have every reason to be satisfied.

SCOTTISH EXPEDITION TO SPITSBERGEN.
DR. WILLIAM S. BRUCE, of the Scottish Oceano-

graphical Laboratory, is conducting another expedition to Prince Charles Foreland and other parts of Spitsbergen. One of the chief objects of the expedition is to complete the survey of Prince Charles Foreland which he began in association with H.S.H. the Prince of Monaco in 1906 and continued in 1907. He will also connect this sur

Dr. Bruce has chartered the steamer Conqueror, which is being specially re-fitted for the purpose, and has selected as master of the ship Captain Francis Napier, who has been kindly lent by Messrs. James Currie and Co., Leith. The expedition will leave Leith on Monday next, July 19, and is expected to be absent about two months.

We understand that this expedition, which will be Dr. Bruce's ninth visit to the polar regions, in no way interferes with his future Antarctic plans.

BIRD NOTES.

To the May number of Naturen Mr. O. J. Lie-Pettersen contributes an account of the life-history of the icterine tree-warbler (Hypolais icterina or H. hypolais) in Norway, where it is known as the "bastard nattergale. The dates of arrival in the neighbourhood of Bergen during. a period of eleven years range from May 16-20 inclusive; birds of the year take their departure about the middle of July, and old birds some weeks later. By the middle of August nearly all have vanished, although an occasional straggler may be seen up to the end of that month, and one specimen was so late as September. Among the trees haunted by this species the hazel is the favourite; nesting takes place at the end of May or early part of June, and the period of incubation is thirteen days.

The April number of the Emu contains the minutes of a conference on Government bird-protection in Australia, held at Melbourne in November, 1908. A large number of species and subspecies were recommended for total protection, among these being lyre-birds, coach whip-birds, emeus, and cassowaries. Owing, however, to the conference being unable to prepare a protection Bill, on account of the relations existing between the Commonwealth and its constituent States, it was eventually decided that the list of species and groups recommended for protection should be submitted to each State for favourable consideration. The urgent need for efficient legislation in this direction is made evident by a statement on another page of the same issue with regard to a recent wholesale slaughter of

emeus.

To Mr. L. J. Cole we are indebted for a copy of a paper from the April number of the Auk on the importance of tagging, or marking, birds as a means of studying their movements. It is pointed out by the author that we are still nearly as much in the dark as regards the true

[ocr errors]

"" inwardness of migration as was the case a century ago, and that practically all our information on this subject is connected with mass-movements, so that we are ignorant of the wanderings of individual birds. The acquisition of a knowledge of such individual movements will, it is urged, aid, not only in the study of the general migration of species, but will assist in analysing the factors connected with migration as a whole. Active measures are being taken to inaugurate a system of bird-marking in the United States.

A similar movement has been started in this country by Mr. H. F. Witherby, the editor of British Birds, the details of which will be found in the June issue of that serial. The rings used for marking are extremely light, and do not in any way interfere with the bird's power of flight; each is stamped Witherby. High Holborn, London," and bears a distinctive number, which in the smaller sizes is stamped inside the ring, and it is hoped that anyone into whose hands should fall a bird so marked will send the bird and the ring, or, if this is not possible, then the particulars of the number on the ring, the species of bird, and the locality and date of capture, to the address given.

Yet another centre for bird-marking is to be established at Aberdeen, as announced in the June number of British Birds.

pose of endowing American colleges and universities. The Board had already received 8,600,000l. from him. Some forty institutions of higher education have benefited by this trust, including Harvard and Yale Universities. The correspondent states that the Board's policy is governed by the belief that every city of more than 100,000 inhabitants should possess a college. The annual income of the Board is said to be 200,000l.

THE accounts of the London Polytechnics for the year ended July 31, 1908, have been printed by the London County Council. The council's comptroller points out that the total ordinary receipts of these eleven institutions amounted to 212,4951., an increase of 8,5431. over the previous year. The council's grants amounted to 80,503., or 37.88 per cent. of the total receipts. Grants from the Board of Education amounted to 38,2291., or 17.99 per cent.; the sums received from the City Parochial Foundation were 27.7041., or 13.04 per cent., and from City companies, &c., 6,929l., or 3.26 per cent. The total ordinary expenditure on revenue account of all the polytechnics amounted to 211,950l., an increase of 4,431l. over previous year. Taking the results as a whole, so far as ordinary income and expenditure are concerned, there was a surplus of 5451. on the institutions, as compared with a deficit of 3,5671. in 1906-7. The amount expended on teachers' salaries reached 99,2861., or 47-84 of the total expenditure; other salaries accounted for 25,500l., or 12.30 per cent.; rent, rates, and taxes absorbed 11,5861., or 5.58 per cent.; and apparatus and other educational appliances and furniture cost 18,3271., or 8.83 per cent. of the total expenditure.

TEACHERS at agricultural schools and colleges in this country will be interested in the full and detailed syllabus issued by the Colorado State Agricultural College. The requirements for admission strike an English teacher as severe, and we can only congratulate the Colorado College if it is in a position to insist on the high standard they imply. The student is expected to have a certain acquaintance with English literature, gained by reading specified classics, and to be "familiar with the essential principles of rhetoric," including the following:-"choice of words, structure of sentences and paragraphs, the principles of

MERELY to mention the titles of four of the six articles contained in the February-March issue of the Southern Educational Review is to demonstrate the importance its editor attaches to the education of the negro. These articles are those on "Results of Attempts at the Higher Education of the Negro of the South, ""The Essential Requirements of Negro Education," "Negro Rural Schools," and "Relation of the State to the Education of the Negro." The review is published at Chattanooga, Tenn., U.S.A., by the editor, Mr. H. Elmer Bierly.

IT is proposed to establish in connection with the Paris University a system of exchange between French and foreign professors on similar lines to that which has for some time been in vogue between Berlin and America. M. Liard, rector of the university, has made an appeal to the friends of the university to create a fund for the purpose. M. Albert Kahn has placed at the disposal of the rector an annual grant of 30,000 francs for five years. The Revue scientifique states that two million francs are necessary for the success of the scheme.

It is announced by the New York correspondent of the Times that Mr. John D. Rockefeller has celebrated his seventieth birthday by giving 2,000,000l. to the General Education Board, which he founded in 1907 for the pur

is another essential subject, and the teacher who is preparing pupils for the college is informed that "the mere learning of a text will not give the preparation that the colleges desire. Effort should be made to cultivate the power of handling facts and of drawing proper deductions from data, to develop the faculty of discrimination, to teach the pupils the use of books, and how to extract substance from the printed page. The other subjectsmathematics, chemistry, physics, "other languages "-are to be taught in a similar spirit. Students so trained would form admirable raw material, and could have no great difficulty in taking the fullest advantage of the college course.

THE Board of Education has issued [Cd. 4736] its regulations for technical schools, schools of art, and other forms of provision of further education in England and Wales which will come into force on August 1 next. No changes of special importance have been made as compared with those of last year. It is satisfactory to note that the amount of each of the royal exhibitions, &c., tenable at the Royal College of Art and the Imperial College of Science and Technology, South Kensington, has been raised from 50l. to 60l. per session. The old royal exhibitions and national scholarships tenable at the Imperial College of Science and Technology, have been combined as royal scholarships, the competition for which is to be conducted on the lines hitherto adopted for the award of national scholarships. In place of the former studentships-in-training in science, the Board of Education has established special studentships for teachers of science and technology who are qualified to enter on the third or fourth year of the course provided at the Imperial College. We notice that in future such teachers-in-training are not to be permitted to continue for more than two years in all at the Imperial College, a change which, in view of the need for highly qualified teachers in our provincial schools of science and technology, seems of doubtful wisdom.

THE new laboratories of St. Paul's School, built to celebrate the quatercentenary of the foundation, were opened on Wednesday, July 8, by Lord Curzon. In his address, Lord Curzon said he noticed how the school had kept pace with the spirit and reforms of the day, how during the last hundred years its numbers had increased from 153 to 500; how the modern side had grown to equal the older side in numbers and importance; and he told how great had been the achievement of the school under the late high master, Dr. Walker, one of the great school-masters of the nineteenth century. Lord Curzon went on to say that we lived in an age of self-depreciation, of a too great selfdepreciation. Foreign critics were always coming to our public schools to learn how, having their superior equipment and their excellent organisation, they might obtain also "that training in character, that sense of moral responsibility, that spirit of civic patriotism, that ordered sense of personal liberty which were among the chief and most honourable characteristics of our public school system." So while content to learn from others we were not to forfeit that in our educational system which had done so much in the civic government of the country and the empire. The Bishop of Manchester referred to the conditions, so different from those obtaining now, under which he had learnt at St. Paul's School; yet he had learnt there that most valuable of lessons, to think. The high master, Dr. Hillard, said that St. Paul's had taken its full share in all those changes in educational method which began with Arnold's life at Rugby.

SOCIETIES AND ACADEMIES.

LONDON.

Geological Society, June 16.-Prof. W. J. Sollas, F. R.S., president, in the chair.-The Carboniferous Limestone of County Clare: James A. Douglas. The district forms

the westernmost limit of the central Carboniferous Limestone plain of Ireland. The area, for the purposes of description, is divided into two main districts. The northern region is formed by an elevated plateau of Viséan Limestone, which rises on the north and east in terraced cliffs, but to the south-west dips below the "Coalmeasure" series. The surface is of bare rock, devoid of vegetation. The southern district is not formed of limestone; the high ground on the east is of Old Red Sandstone and Silurian rocks, that on the west of Coalneasures. The older formations appear as two anticlinal flexures, forming the mountains of Slieve Aughty and Slieve Bernagh. The margin of the syncline is formed by Tournaisian shales and limestone, while the Viséan limestones occupy the core. The limestone fauna show that the Geological Survey boundary between the Upper and Lower Limestones corresponds with the transition from a Tournaisian to a Viséan fauna, and the Middle Limestone contains a fauna distinct from that of the Upper, although they are not separable on lithological grounds. The Old Red Sandstone is succeeded by a series of sandy shales containing brachiopods characteristic of the Cleistopora zone; at the base are found modioliform lamellibranchs. The Zaphrentis zone is well developed. The most remarkable portion of the whole sequence is included in the Syringothyris zone. These beds show evidence of deposition in shallow water. The fauna is compared with that of the Waulsortian phase of Belgium. The incoming of a Viséan fauna is well marked at the base of the Seminula zone; in the middle of this zone occurs an important bed of oolitic limestone, with abundant gasteropods. The Dibunophyllum zone attains a thickness equal to that of the Midland area.-The Howgill Fells and their topography: J. E. Marr, F.R.S., and W. G. Fearnsides. The Howgill Fells form a monoclinal block, from which the Carboniferous rocks have been denuded. The northern slope probably corresponds with the sloping plane of unconformity between the Carboniferous rocks and Lower Palæozoic strata. On the south the slope to the Rawthey is along a block-fault. The chief drainage was originally north and south from the watershed at the summit of the block. The tract was

truncation of spurs, the formation of conchoidal scoops in the concavities of the valleys, a general widening of the valleys, and but slight deepening. A feature of interest is the contrast in this small area between these glaciated valleys and others of V-shaped cross-section, which are typical water-carved valleys unaffected by glacial erosion. -A new species of Sthenurus : L. Glauert.-Some reptilian remains from the Trias of Lossiemouth: D. M. S. Watson. The fore-limb of Ornithosuchus woodwardi is shown in a specimen in the Manchester Museum. Ornithosuchus is restored as an animal walking on all fours, with the head carried rather low. The proportions are identical with those of Etosaurus. A description is given of the skeleton of a very small reptile, interesting as recalling tosaurus in its armour.-Some reptilian tracks from the Trias of Runcorn (Cheshire): D. M. S. Watson. Four types of tracks which occur on the slab of sandstone from Weston Point, described in 1840 by Dr. Black, are discussed in this paper. It is suggested that some of these prints may quite well belong to such thecodonts as Ornithosuchus.-The anatomy of Lepidophloios laricinus, Sternb.: D. M. S. Watson.

Linnean Society, June 17.-Sir Frank Crisp, vice-president, in the chair.-The growth of a species of Battarea : J. G. Otto Tepper.-The deposits in the Indian Ocean : Sir John Murray.-The Sealark Penaeidea, Stenopidea, and Reptantia: L. A. Borradaile.—The Sealark Lepidoptera: T. B. Fletcher.-Report on the Porifera collected by Mr. C. Crossland in the Red Sea, part i., Calcarea: R. W. H. Row. The African species of Triumfetta, Linn. T. A. Sprague and J. Hutchinson.-New species of Malesian and Philippine ferns: Dr. H. Christ.-The acaulescent species of Malvastrum, A. Gray: A. W. Hill. DUBLIN.

Royal Dublin Society, June 22.-Dr. J. M. Purser in the chair. The fossil hare of the ossiferous fissures of Ightham, Kent, and on the recent hares of the Lepus variabilis group: M. A. C. Hinton. The paper describes the fossil remains of Lepus variabilis, Pall., obtained from the rock fissures at Ightham, and deals with the osteology of the recent and fossil hares of the L. variabilis group. The Pleistocene hare of England is referred to a new subspecies, L. variabilis anglicus, which is to be regarded as the immediate ancestor of L. variabilis hibernicus, its relationship with the existing Scotch form not being so close. The subspecies anglicus and hibernicus are shown to be the most primitive members of the variabilis group. The most important conclusion reached is that, contrary to the prevalent view, the variabilis group of hares has originated in temperate latitudes, and not in the high north. The value of benzidine for the detection of minute traces of blood: Prof. E. J. McWooney. The author began by explaining the chemical nature of benzidine, which is a di-p-diamino diphenyl. This substance, when dissolved in acetic acid and brought into contact with blood in presence of H,O,, at once undergoes oxidation with formation of a brilliant blue colour. The reaction is in principle the same as that with guaiacol, the old-fashioned Van Deen's or Schönbein's guaiacum test. The colour base from guaiacol differs from the benzidine colour-base in the same way as an amine (aniline) differs from a phenol, or an aurine from a rosaniline dye. The test is ten-fold more delicate than that with guaiacum, and detects blood in solution as weak as 1/500,000; but for medicolegal purposes it is preferable to bring particles of the suspected matter into contact with the reagent, when each granule, if blood, at once strikes a most brilliant blue. The reaction can be observed under the microscope. The test worked well with blood-stains many years' old, and seemed to be independent of the nature of the substratum. Controls, and a time limit of about a minute, were essential, and the sensitiveness of each batch of benzidine had to be worked out beforehand. Of all the substances tested, none gave the typical blue colour so speedily as blood, save fresh vegetables and fruit, which at once struck an intense blue, at first limited to the fibro-vascular bundles. Boiling deprived them of this power, owing to the destruction of the oxydase, whereas blood solutions gave the blue reaction at once after five minutes' boiling. The author recommended this test to the attention of medical jurists.

PARIS.

Academy of Sciences, July 5.-M. Émile Picard in the chair. Some new trialkylacetophenones and the trialkylacetic acids derived from them: A. Haller and Edouard Bauer. It has been shown in a preceding communication that dialkylacetophenones can be converted into trialkylacetophenones by treatment with an alkyl iodide in benzene solution in presence of sodium amide. These trisubstituted ketones, when further heated with sodium amide in toluene give a nearly quantitative yield of the amide of the trialkylacetic acid, together with benzene. In the present paper alkyl groups of high molecular weight are introduced. It has been found that on treatment with sodium amide these trialkyl ketones always give the fatty amide, the expected change into benzamide and the trialkylmethane not being effected. The preparation and properties of several new ketones are described. The tectonic relations of the island of Elba with Corsica, and the situation of the latter in the Alpine chain Pierre Termier.-The new Recueil of levellings of Russian railways as a basis for the hypsometry of the country J. de Schokalsky.-Central Asiatic Russia and the level of the lake basins: J. de Schokalsky. There is evidence that the levels of the Siberian lakes are slowly rising. This is connected with the fact that the annual rainfall for the last twenty years has been slowly increasing. It is possible that there are alternate dry and wet periods in Siberia, and that at the present time the wet period has passed its maximum.-M. J. C. Kapteyn was elected a correspondant in the section of astronomy.Occultations of stars observed at the Observatory of Lyons with the Brunner 16-cm. equatorial during the eclipse of the moon of June 3: J. Guillaume. The summation of Dirichlet's series: Marcel Riesz.-The singular integrals of certain algebraical differential equations: B. Gambier.Linear differential equations and uniform transcendentals of the second order: René Garnier.-Some inequalities having a bearing on the theory of elastic vibrations and electrical vibrations: A. Korn.-The conductivity of a gas at atmospheric pressure under the influence of a high alternating voltage: A. Chassy. The conductivity of a gas increases continuously with the voltage, and it is only for the highest voltages well above the critical voltage that the capacity of the gas condenser is the same as that which would be obtained if the gas were replaced by a liquid conductor. It is possible that under these conditions the gas is a true conductor and follows Ohm's law. The radio-activity of potassium salts: Emile Henriot and G. Vavon. The minute radio-activity shown by potassium salts would appear to be a property of the potassium atom, since all attempts to concentrate the radio-activity by a series of fractionations failed. This confirms the results of Campbell and MacLellan. The rays have been identified with the B rays. Tautomeric changes elucidated by means of the magnetic rotatory power: P. Th. Muller and M. Thouvenot. A differential method was employed to increase the sensitiveness of the measurements. Experiments were made with methyl cyanacetate and its sodium salt and with acetoacetic ester and its sodium derivative. The results indicate a change in the internal structure when the molecule passes into the sodium derivative.-The chlorides of silicon: A. Besson and L. Fournier. The evolution of hydrogen from silicochloroform under the action of the silent discharge has been confirmed by working in a current of hydrogen chloride gas.-A new method for the isolation of terbine: G. Urbain.-The oxidation of aldehydes by silver oxide: Marcel Delépine and Pierre Bonnet. The aldehyde in aqueous solution is mixed directly with silver nitrate, and baryta solution added in a proportion sufficient to set free the silver oxide and neutralise the organic acid formed. Various applications of the method are given, the yields being very high, usually more than 90 per cent. of the theoretical.-The hydrolysis of proteid materials by means of hydrofluoric acid; some new results: Hugounenq and A. Morel. By varying the strength of the hydrofluoric acid used for the hydrolysis the reaction can be stopped at definite stages. The process is especially advantageous for the isolation of the simple peptides.Study of the principal layers of the alkaline rocks of the French Soudan: G.

Griffon.-The biometrical study of the seeds of Vitis vinifera: P. Seyot.-The supposed utilisation of atmospheric nitrogen by certain special hairs of plants: François Kövessi. The development of plant hairs is independent of the presence of atmospheric nitrogen, and there is no evidence that these organs have specialised absorptive powers for nitrogen.-Seeds killed by anææsthetics retain their diastatic properties: Jean Apsit and Edmond Gain. Grains of wheat, the germinating power of which had been destroyed by treatment with ether, retained both their diastatic and peroxydiastatic properties. The sensation of relief: A. Quidor. The presence of attractive spheres and of centrosomes in the cells resulting from the parthenogenetic segmentation of the fowl's egg, and on the characters of these formations: A. Lécaillon.
