matter of fact, no warp is carried into the river from the sea, but that the warp in suspension is derived entirely from the solid matter brought down by the various tributaries of the river. The paper describes this matter as oscillating backwards and forwards with the tides in a zone confined to the lower reaches of the Ouse and the Trent, except that when heavy freshets are running it extends into the Humber and is then partly carried out to sea. This peculiar action is made use of to improve the value of the land adjacent to the rivers by the process of "warping." Any solid matter brought into the Humber on the flood tide consists entirely of clean sand, and has no relation to the waste of the Holderness coast. The only novel features, therefore, in these papers is the suggestion of Mr. Carey that the matter should be taken up by Parliament, and that a body of commissioners should be created with the special function of dealing with the foreshores of England and Wales. He proposes that the coast should be divided into districts placed under commissioners, each having an engineer to act as coast warden, with power to deal with the material on the beach, and the general control and management of all foreshore lands, the costs incurred by this commission to be divided between the Treasury, the local authorities, and the landowners. Mr. Matthews confines his ideas of Government interference to the coast of Yorkshire, and suggests that this ought to be protected against the inroads of the sea by the Government, quoting as a precedent for this that the Board of Trade protects the Spurn Peninsula. He loses sight, however, of the fact that this is done for the protection of the lighthouses which stand on the peninsula, and for the preservation of the entrance to the Humber. Mr. Matthews gives an estimate for protecting this reach of coast by sea walls and groynes, and shows, as has been done by others on previous occasions, that the value of the land swallowed up by the sea within a reasonable period would not amount to one-third of the first cost of the protective works, apart from their maintenance. It will be remembered that recently, owing to the great destruction of sea protective works that occurred at Lowestoft and Southwold, the representatives of the sea coast towns on the east of England held a conference at Norwich and appointed delegates to interview the Prime Minister and the officials of the Government departments more particularly concerned in this matter, urging that the preservation of the coast and the sea defence works ought to be a national charge. So far, however, they do not appear to have justified their claims for such aid. It has been pointed out that most of these towns have gradually emerged from mere fishing villages into sea-side resorts, and have erected promenades and other similar works for the purpose of making their places popular, and have by this means increased the value of the land in the neighbourhood from a mere agricultural price to that of building land, very greatly to the profit of the owners of such land. It appears therefore manifestly unfair to ask the owners of the agricultural land at the back, whose rents have already been greatly depleted by the fall in value of agricultural produce during the last few years, to contribute towards works for the improvement of their neighbours' land on the coast, which they would have to do if these works were made a charge on the national revenue, and it would be equally unjust to levy contributions on inland towns which have borne the costs of large improvements for sanitary and health purposes out of their own rates. Mr. Carey describes in his paper the evolution of a sea-side village, subject to intermittent inundation, into a watering place, in front of which the local authority charged with the works not only encloses within the sea wall nearly the whole of the shingle beach which afforded a natural protection to the shore, but also by groynes traps the whole of the travelling shingle, with disastrous results to the owner of the land to leeward. It may also be pointed out, as stated in the British Association report for 1895, that many of the disasters that occur to the sea walls and promenades of these sea-side towns are due to defective engineering and a complete disregard of the laws of nature. It is obvious that it would be very desirable to set up some better control over the works now carried on along the sea shore either by increasing the powers of the Board of Trade or by the appointment of a special commission, as suggested by the author of the paper. The great difficulty will be in dealing with the rights of the persons claiming the ownership of the beach material, which in many cases is sold and removed in very large quantities for concrete making, road repairs, or other purposes. The Board of Trade occasionally, on being applied to, intervenes and issues notices prohibiting the removal of sand and shingle, but its power to do so is not so well defined as it ought to be, and the whole subject requires investigation, and legislative action for regulating and controlling works carried out on the sea shore and the removal of beach material; but the preservation of the property of landowners and urban authorities out of funds provided from the national exchequer would be entirely contrary to the methods of administration hitherto pursued in this country. THE NOVEMBER METEORS OF 1904. THOUGH there was no prospect of a brilliant display this year, there seemed the probability of a pretty conspicuous shower. In 1838-five years after the great meteor-storm of 1833-Mr. Woods, of London, reported in the Times that on the night of November 12, between 15h. 25m. and 15h. 55m., "nothing could exceed the grandeur of the heavens. Meteors fell like a shower of bombshells in a bombardment and in such rapid succession as to defy every attempt to watch their particular directions or to ascertain their numbers.' Mr. Woods estimated that he saw 400 or 500 meteors during the half-hour mentioned. In 1872 also, about five years after the brilliant displays in 1866, 1867, and 1868, the Leonids returned pretty abundantly, for on November 13, 12h. to 18h., several observers at Matera, Italy, counted 638 meteors, and the display was regarded as having been much brighter than usual. In these circumstances it was expected that the return of 1904 would be deserving of careful observation, and so it has proved, though the shower was perhaps not quite so rich as expected. The earth, however, probably passed through the denser part of the stream at about Greenwich noon on November 15, and thus it must have escaped observation in England. Reports from American stations are awaited with interest. In this country fogs were very prevalent at the important time, and at some places appear to have obliterated the phenomenon. At Bristol during the night of November 13 there were very few meteors visible, with only occasional Leonids, but the stars were dim in the fog. On November 14 the conditions were more favourable. Between 13h. 30m. and 15h. 45m. about 55 meteors were seen (including 33 Leonids) by the writer during a watch extending over 1h. of the period named. It was considered that Leonids were appearing at the horary rate of 25 for one observer. After 16h. increasing fog interfered with observation. The Rev. S. J. Johnson at Bridport had, however, a very clear sky after 16h., and noted a fairly numerous display of Leonids, including one as brilliant as Venus and several equal to Jupiter. He does not mention the exact number seen. Mr. C. L. Brook at Meltham, near Huddersfield, watched on November 14 between 16h. and 18h., and counted 69 Leonids, of which number 17 were observed in the first quarter of an hour. Other results have come to hand which corroborate Mr. Brook's figures, and show that the maximum was attained between 15h. 50m. and 16h. 20m., when the rate of apparition was 1 Leonid per minute in the sphere of vision commanded by one observer. There appear to have been very few Leonids seen either on the nights of November 13 or 15. As observed at Bristol, the radiant seemed to be an area 4 or 5 degrees in diameter, with its centre slightly west of y and Leonis, or at 151°+23°. There were several minor showers visible, and two of these were well pronounced at 43°+21° and 144° + 37°. W. F. DENNING. UNIVERSITY AND EDUCATIONAL INTELLIGENCE. OXFORD.-The Rhodes trustees have decided to add 200l. a year for the next five years to the stipend of the reader in pathology. Mr. Alfred Beit and Mr. Wernher have supplied sufficient money to endow a professorship of colonial history, and to appoint an assistant professor in the same subject. They have also made a gift to the Bodleian Library. Magdalen College has made a grant to the delegates of the university museum of 250l. a year for the next two years for the purpose of the payment of scientific assistants. The following examiners have been appointed :—in chemistry, W. H. Perkin, jun.; in preliminary physics, E. S. Craig; in preliminary chemistry, J. E. Marsh; in preliminary animal physiology, W. Ramsden; in preliminary zoology, E. S. Goodrich; in medicine, organic chemistry, N. V. Sidgwick; in human anatomy, A. Thomson; in materia medica, R. Stockman; in midwifery, J. S. Fairbairn; in pathology, G. Sims-Woodhead; in forensic medicine and public health, J. D. Mann and A. L. Ormerod ; and in human physiology, L. E. Hill. THE alumni of the Massachusetts Institute of Technology are collecting, says Science, a fund for current expenses, which now amounts to more than 20,000l., to be used in the course of the next five years. We learn from the same source that Harvard University has received from Miss Whitney a gift of 1000l., the income of which is to be applied as a scholarship to aid meritorious students in the study of field geology or geography in the summer months, preferably in the mountain region of the western United States. APPLICATION will be made to Parliament in the ensuing session for an Act to transfer University College, London, exclusive of the North London or University College Hospital, the medical school, and the boys' school, to the University of London, and to dissolve or provide for the dissolution of the college itself. The Bill will contain a clause authorising and providing for the making by the Senate of the university, or by such other body or persons as the Act may prescribe, of statutes and regulations for the management of the college; and provision will also be made for carrying on the work of the hospital, the medical school, and the boys' school. THE new buildings of the Borough Polytechnic Institute were opened by Mr. Benn, chairman of the London County Council, on November 16. The buildings, which were urgently needed for the large number of students, have cost with equipment more than 24,000l. Toward this amount the central governing body of the City of London Parochial Charities contributed 3000l., the London County Council 16,000l., with a promise of a further sum. The council also meets the cost of installation of the electric light and equipment, amounting to 2950l. The total cost of the land, about 1 acres, buildings and equipment, by the end of the year will be not less than 96,000l. WITH the object of giving to the school children of the United Kingdom better knowledge of the colonies, and of giving to the school children of each colony better know ledge of the United Kingdom and of other parts of the Empire, a syllabus of seven lectures on the United Kingdom, each to be illustrated by about forty lantern slides, has been drawn up by a committee connected with the Colonial Office. The subjects of the lectures are: (1) the journey from the East to London; (2) London the Imperial city; (3) scenery of the United Kingdom; (4) historic centres and their influence on national life; (5) country life and the smaller towns; (6) great towns, the industries, and commerce; (7) defences of the Empire. Mr. H. J. Mackinder will give an account of the scheme, and exhibit some of the slides which have been prepared to illustrate it, at the Whitehall Rooms, Hôtel Métropole, on Wednesday, December 7, at 5 p.m. The Colonial Secretary has consented to preside. Ar the inaugural meeting of the new session of the Royal Statistical Society on November 15, the new president, Sir Francis Sharp Powell, Bart., M.P., delivered an address on education in which he presented specially impressive figures to illustrate prominent educational features of various countries. The activity in educational matters of to-day was commended, and attention directed to the growing conviction that a more liberal education than that provided by purely technical instruction is necessary in this country. Among other interesting comparisons instituted in the address was one dealing with the average expenditure on education per child in Prussia and in England. Exclusive of central and local administration, it appears that the average expenditure per child on the register is in Prussia 1l. 15s. 6d. if buildings are included, and l. 10s. 8d. exclusive of buildings. The corresponding figures in England are 2l. 128. 9d. and 1l. 17s. Further, the number of scholars per teacher is 66 in Prussia and 57 in England, excluding pupil teachers. It seems clear from these figures that Germany, with a smaller expenditure per child than our own, succeeds in securing better results, and it is to be hoped that English education soon may be conducted more scientifically, so that the value of our education may be more in accordance with our expenditure. The address also pointed out that in secondary education German activity is shown in the provision of technical schools for special branches of metal industries, for wood-working, engineering, and textile industries, and for agriculture. SOCIETIES AND ACADEMIES. LONDON. Royal Society, June 16.-" Hydrolysis of Cane Sugar by d- and l-Camphor-8-Sulphonic Acids." By R. J. Caldwell, B.Sc. The rates of inversion of cane sugar by two stereoisomeric acids were determined in order to compare the results with the case of inversion by enzymes, which are apparently all asymmetric substances. Wilhelmj's law holds accurately for half normal solutions of both dextro- and lævo-camphorB-sulphonic acids. The velocity constant KC (equal to 10/t log1, a/a-x, where a is the initial cane sugar concentration, and x the concentration of the inverted sugar at the end of t minutes) was found to be 10 07 and 10-13 in two experiments with the dextro-acid, and 10.05 and 10.08 for the lævo-acid. The author concludes that there is no difference in the inverting power of the two acids attributable to their asymmetric structure. This result is in accord with the conclusion arrived at by Emil Fischer regarding the d- and l-camphoric acids (Zeits. Physiol. Chem., 1898. vol. xxvi. p. 83). The relative activities of hydrochloric acid and camphor-B-sulphonic acid towards cane sugar are 100 90, whereas for milk sugar the ratio is 100: 70. November 17.-" Enhanced Lines of Titanium, Iron, and Chromium in the Fraunhoferic Spectrum. By Sir J. Norman Lockyer, K.C.B., LL.D., F.R.S., and F. E. Baxandall, A.R.C.S. In this paper the authors give the results of a detailed study of the enhanced lines of Ti, Fe, and Cr in relation to the lines of the Fraunhoferic spectrum. In previous Kensington publications it had been shown that the enhanced lines of some of the metals are prominent in the spectra of a Cygni and the sun's chromosphere, whilst it has been generally recognised that the lines in the Fraunhoferic spectrum are mainly the equivalents of lines in the arc spectra of metals. In connection with the work on enhanced lines, it has been noted that some of them, at least, appear to correspond with comparatively weak solar lines to which Rowland has attached no origin. With the object of possibly tracing some of the unorigined solar lines to their source, a careful comparison has been made between the enhanced lines shown in the photographic spark spectra of Ti, Fe, and Cr and the solar lines. The photographs used for this purpose were all taken with a Rowland grating, and on such a scale that the length of spectrum between K and F is about 14 inches (35 cm.). The chemical elements named were first selected for investigation because they furnish by far the greater number of enhanced lines which have been shown to occur in the spectrum of a Cygni. It was found that many of the enhanced lines fell exactly on isolated lines of the solar spectrum, and in these cases the solar wave-lengths were adopted and the identification considered established. If, however, for any of these solar lines Rowland had given alternative origins, special comparisons were made of the enhanced line photograph with those of the metals given by Rowland. Notes (given at the end of the tables) were made as to the agreement or non-agreement of the metallic lines involved, and also of the relative intensities in their individual spectra, so that due weights could be given to the respective metallic lines which were thought conjointly to produce compound solar lines. Where there was any doubt as to the exact coincidence of a metallic and solar line, or where by the close grouping of several solar lines it was not possible to say by direct comparison to which solar line the metallic line corresponded, careful measures were made of the metallic line, and its wave-length found by interpolation between closely adjacent lines of known wave-length. The resulting wavelengths were then compared with Rowland's solar wavelengths, and in cases of close agreement with solar lines it was deemed probable that the two lines were really identical. A final table is given of the enhanced lines of the three elements which are considered, as a result of the analysis, to be identical with lines in the Fraunhoferic spectrum. Forty-two of these agree with solar lines unorigined by Rowland, and as the majority of them are conspicuous lines in stellar spectra of certain types, it has been thought that these results will be of importance in standardising the wave-lengths of many stellar lines. Physical Society, November 11.-Dr. R. T. Glazebrook, F.R.S., president, in the chair.-Investigation of the variations of magnetic hysteresis with frequency: Prof. T. R. Lyle. The experiments were made on two rings of laminated annealed iron, in one of which the radial breadth of the iron was considerable relative to its mean radius. These rings were magnetised by alternating currents of different strengths and periods; both the magnetisingcurrent wave and the magnetic-flux wave were quantitatively determined by a wave-tracer (described by the author in the Phil. Mag., November, 1903), and the wave-forms so obtained subjected to harmonic analysis. The experiments were divided into series, in which the period and wave-form of the magnetising current were kept as nearly constant as possible throughout any one series, while its strength was varied. The analytic expressions for the associated current and flux waves for a few series are given in tabular form. From the analytic expressions for each pair of associated waves it was found that when the magnetising current was approximately sinusoidal the total iron loss (I) was, within certain limits of the induction, given by a formula I=(a+bn) B1, where n is the number of periods per sec., B the "effective induction," and a and b are constants. When from the total iron loss per c.c. per cycle the sum of the statical hysteresis and the value that theory assigns to eddy-current loss was subtracted, a considerable quantity remained, which increased both when the frequency and the flux-density increased. This quantity, called by Fleming the kinetic hysteresis, has been obtained for each experiment.-On the practical determination of the mean spherical candle-power of incandescent and arc lamps : G. B. Dyke. Mr. Dyke points out the need of an improved method of expressing the efficiency of glow-lamps, and adopts the suggestion of Dr. Fleming of expressing the whole flux of light in lumens per watt. The expression of the efficiency in this manner involves the determination of the mean spherical candle-power (M.S.C.P.), and the paper describes a method of doing this. The objects of the paper are :-(1) to obtain curves showing the variations of candlepower of glow-lamps in a horizontal plane; (2) to obtain reduction factors by which the mean horizontal candlepower (M.H.C.P.) may be calculated from the maximum horizontal candle-power (C.P.); and (3) to obtain reduction factors for deducing the M.S.C.P. from the M.H.C.P. and from the C.P.-Exhibition of apparatus : R. W. Paul. The construction of highly sensitive pivoted electrical instruments has been rendered difficult by the fact that delicate pivots will not admit of transporting without injury. A number of galvanometers were shown in which the design was based upon the use of a moving coil, supported on one pivot in a powerful and uniform magnetic field, and controlled by a spring. A simple non-reflecting, suspended-coil galvanometer for the student's use, with a sensibility of I division per micro-ampere, was also exhibited. A new design of lantern, adapted for science lectures, and for use with three Nernst filaments arranged closely together, was shown in action. It is capable of being instantly changed from horizontal to vertical projection, can be fitted with a reversing prism, and has a wide adjustment for focusing. Another exhibit was an Ayrton Mather reflecting electrostatic voltmeter with a magnetic damping device. The instrument shown had a sensibility of 500 mm. at 1 m. for 30 volts, but similar instruments are made to give this deflection with pressures as low as 8 volts. PARIS. Academy of Sciences, November 14.-M. Mascart in the chair. Researches on the desiccation of plants: the period of vitality. Moistening by liquid water: imperfect reversibility M. Berthelot. New researches : on the Cañon Diablo meteorite: Henri Moissan. A very careful and complete examination was made of a block of this meteorite weighing 183 kilograms. It was found to be distinctly heterogeneous in structure, containing iron, nickel, sulphur, phosphorus, silicon, and carbon. The latter element was present in several forms: amorphous carbon, graphite, and diamonds, both the black and transparent variety of the diamond being separated. Characteristic green hexagonal crystals of silicon carbide were also isolated, the author remarking that this is the first time that this compound has been met with in nature.-The measurements of the velocity of propagation of earthquakes: G. Lippmann. An instrument is described capable of determining to 1/5 of a second the exact time of the commencement of a seismic shock at any given point. The author also discusses the following problem to find the direction of the seismic wave front at the surface of the earth, in a given region, and to measure the velocity of its horizontal propagation.-On the inscription of seismic movements: G. Lippmann. In the photographic self-recording apparatus in common use for earthquake phenomena, owing to the considerable expense of the strip of sensitised paper, its velocity through the apparatus is very slow, about 12 cm. per hour. In the modification now proposed, the slit through which the ray of light falls on the paper is closed by a shutter, and this is operated electrically by the seismic shock. By this means the speed may be greatly increased, since the paper is only used up during the period of the earthquake shocks.-On the seeds of the Neuropterideæ: M. Grand'Eury. As the result of the examination of more than 1000 specimens of fossil seeds, usually attributed to ferns, the author distinguishes 15 genera or subgenera of Neuropteridea, and 25 specific types.-Remarks on Hugoniot's adiabatic law : M. Jouguet. On the use of helium as a thermometric substance and on its diffusion through silica: Adrien Jaquerod and F. Louis Perrot. An attempt to determine the melting point of gold with a thermometer of fused silica, and containing helium, failed owing to the rapid diffusion of the gas through the silica at the high temperature. The velocity of diffusion appears to be proportional to the pressure of the gas, and is very considerable, since after six hours' heating at 1100° C. the pressure of the helium had fallen to about one-seventh of the initial pressure. Below a red heat, at about 510° C., the diffusion is still fairly rapid, and a very slow effect could even be traced at 220° C. For practical purposes, therefore, the nitrogen thermometer remains the best instrument for high temperatures. Researches on dielectric solids: V. Crémieu and L. Malcles. In the course of his researches on electric convection, Crémieu observed some anomalies of electrical influence through solid dielectrics. The authors have commenced a systematic study of these phenomena, and give an account in the present paper of the apparatus used, reserving the results for a future communication.-On the conductivity of gases from a flame: Paul Langevin and Eugène Bloch. The coefficient of re-combination of the ions from a flame has been measured, and found to be equal to about 07. This value is less than one, as the theory requires, and is much greater than in the case of the Röntgen rays. On the absorption of hydrogen by rhodium : L. Quennessen. Contrary to the statement given in the text-books, the absorptive power of rhodium for hydrogen is nil. Rhodium is not analogous with palladium in this respect. The action of boric acid on the alkaline peroxides and the formation of perborates: George F. Jaubert. By the action of boric acid upon sodium peroxide a perborate of sodium is formed, the analysis of which leads to the composition Na,B,O,10H2O. On re-crystallising this a substance possessing more oxygen, NaBO,,4H,O, is formed, and this is very stable at the ordinary temperature, although decomposed rapidly at 100° C. The latter substance, treated with 50 per cent. sulphuric acid, gives after filtration through guncotton a solution of hydrogen peroxide of a strength of 150 to 200 volumes.-On thioformic acid: V. Auger. The author has shown in a previous paper that the substance regarded by Wöhler and Limpricht as thioformic acid is in reality trithioformaldehyde. The method which was found to give the best yield of sodium thioformate was the interaction of sodium hydrogen sulphide with phenyl formate. The latter substance was incidentally obtained in the pure state for the first time, and details of its preparation are given.-The synthesis of BB-dimethyladipic acid G.
