pyrazolones has been extended to the alkylpropiolic esters. The pyrazolones can also be obtained when the ester is replaced by the amide or by the B-oxyalkylacrylic esters obtained from the acetylene compounds by a method described in a previous paper. The theory of the reactions is discussed.-Phenyl migrations in the halohydrins and in the a-glycols: M. Tiffeneau.—Cinnamenyl-paraconic acid : J. Bougault. Researches on the relations of functional groups in distant positions: cyclic amines: E. E. Blaise and M. Houillon. Octamethylene diamine chlorhydrate gives by the action of heat an unsaturated hydrocarbon and a secondary cyclic base. This has been proved to be identical with a synthetically prepared specimen of butylpyrrolidene. -The basicity of the xanthyl oxygen: R. Fosse and L. Lesage. A description of a series of double salts, of which xanthyl-lead bromide, CH(C ̧H1),O.Br+2PbBr1, may be given as a type. The production of Ascidia by traumatisms: L. Blaringhem.-The origin of the materials utilised by the ovary: Jean Friedel. The assimilating power possessed by the green carpels of many plants is well known. From experiments on Ranunculus acris the author concludes that the ovary utilises both its own products of assimilation and the reserves of the peduncle. If the conditions in which it is placed suppress one of these two modes of nutrition, the ovary can arrive at complete development from the other. The longevity of seeds: Paul Becquerel. Experiments were carried out on 550 species belonging to fifty families, the age of which varied from twenty-five to 135 years. The only seeds preserving their vitality for more than eighty years were those protected by a thick skin and possessing slightly oxidisable reserves.-A disease of the plane tree due to Gnomonia veneta : J. Beauverie. Some new Madagascan Asclepiadaceæ producing caoutchouc; J. Costantin and I. Gallaud.-The biology of the Virgularia: Ch. Gravier.-A new form of operculated Cirripede, Pyrgopsis Annandalei : A. Gruvel. Prehistoric remains in the neighbourhood of Kayes, Soudan: Fr. de Zeitner. The deposits of stone instruments are large, and formed out of rocks still existing in the district. The instruments cannot be classified with any of the usual European types, are highly polished, and show considerable skill in their manufacture. It is impossible at present to fix their age. A method of isolating the hæmatablasts of the blood in a state of purity: L. Le Sourd and Ph. Pagniez.-Researches on animal electricity: MM. Girard and Victor Henri. The role of the cellular elements in the transformation of certain carbohydrates by the intestinal juice H. Bierry and A. Frouin.-The problem of statical work: Ernest Solvay. A criticism on a paper of M. Chauveau on the same subject.--The sensibility of the retina for luminous radiations: Milan Štefánik. Using a spectroscope with glass prisms and a suitable coloured screen the red end of the spectrum is visible with sufficient clearness for measuring the lines down to λ 3830. The photographic results obtained by M. Millochau with the same apparatus give the same limit. It follows that the retina is sensible for all the radiations which pass the spectroscope.-The use of sodium chloride in the histological impregnation of tissues by silver: Ch. Achard and M. Aynaud. An experimental proof of the view recently put forward by M. Quinton that the results are due to the presence of sodium chloride in the intercellular spaces, the chloride of silver thus formed darkening in the light.-A method of detecting iron in living tissues: A. Mouneyrat. -Study of the transmissibility of tuberculosis by alimentary casein: Marcel Guédras. Food products for infants containing dried casein as a base may transmit tuberculosis. Casein dried at a low temperature may still contain the tubercle bacillus.-The extension of the marine invasion of the upper Sparnacian in the neighbourhood of Paris Paul Combes, jun.-The existence of the Cretacean in the Oran schists: MM. Ficheur and Doumergue.The Yprés clays of the department of Aisne and the climatic conditions at the Lutetian epoch: Paul Fritel.The trajectory of electric corpuscles in space under the influence of terrestrial magnetism, with applications to the aurora borealis and to magnetic disturbances: Carl Störmer. Two relief maps of Paringu and Soarbele (Southern Carpathians) executed from unpublished topographical sketches: E. de Martonne.

CALCUTTA.

Asiatic Society of Bengal, June 6.-Indian meteorites recently acquired by the Geological Survey: L. L. Fermor. The crusts of some of them show interesting flow-structures. (1) Notes on a rare Indo-Pacific barnacle. Remarks on Conchoderma hunteri, Owen, which the author, agreeing with Hoek, regards as a variety of C. virgatum (Spengler). (2) Contributions to Oriental herpetology. No. 4. Notes on the Indian tortoises. Remarks on some obscure species, with a list of the Indian Chelonia (3) Notes on the common Hydra of Bengal: Dr. N. Annandale. The systematic position of Hydra orientalis is discussed, with a description of its anatomy. As the result of two years' investigation, the author concludes that the species is dioecious, but that sexual reproduction plays an unimportant part in the life cycle.-Rawats and Merāts of Rajputana: R. C. Bramley.-An old reference to the Bhotias H. Beveridge.-Parasites from the Gharial (Gavialis gangeticus, Géoffr.): Dr. von Linstow. Two new nematodes, each representing a new genus, and a new linguatulid are described. The former were found in the stomach and on the mesentery; the latter in the lungs and trachea.

NEW SOUTH WALES.

Royal Society, May 2.-Mr. H. A. Lenehan, presi dent, in the chair.-Annual general meeting. An address was delivered by the president.-A specimen of diamond in the matrix: E. F. Pittman. The specimen was found by Messrs. Pike and O'Donnell in their claim at Oakey Creek, near Inverell. The diamond is a small one, weighing about one-third carat, and the material in which it is embedded is an igneous rock known as dolerite. The dolerite occurs at Oakey Creek as a pipe or dyke, and the specimen is of special interest as throwing some light upon the question of the origin of the diamond.
