±'aris. 

 Academy of Sciences, July i.— M. Leon Guignard in 

 die chaii-. — G. Bigourdan : The observatory of Godin, 

 Fouchy, and de Bouguer : its co-ordinates. — M. 

 Hamy : The deterniinalion of radial velocities with 

 the objective prism.— G. Charpy : The influence of 

 forging and rolling {corroyage) on the mechanical 

 properties of steel. It is generally accepted that cast- 

 steel ingots must be forged or rolled hot until the 

 final section is reduced to between one-third and one- 

 fourth the original section. This involves a consider- 

 able expenditure of fuel and labour, and experiments 

 are given by the author w'hich suggest that this hot 

 working does not really improve the metal ; the 

 strength is increased in one direction, but reduced in 

 another. — M. Trabut was elected a correspondant for 

 the section of rural economy in succession to the 

 late M. Yermoloff. — J. An^rade : A family of dis- 

 placements and a generalisation of the dihedron. — 

 P. Humbert : Two polynomes associated with the poly- 

 nomes of Legendre. — C. Raveau : Thermodynamics 

 based entirely on Carnot's principle. A second abso- 

 lute temperature.^ — Ed. Chauvenet and Mile. H. 

 Gueylard : The combinations of neutral zirconyl sul- 

 phate with some alkaline sulphates. From thermo- 

 chemical measurements the existence is indicated 

 of the double salts [(ZrO)SOJ,.2Na„SOj and 

 [(ZrO)SOj3.2(NHJ,SO„ together with " the two 

 corresponding containing 7H2O. — A. Valeur : The 

 presence of a non-volatile alkaloid in the broom 

 (Sarothamnus scoparius). This new alkaloid was 

 isolated from the last mother liquors obtained in the 

 successive crystallisations of commercial sparteine sul- 

 phate, and the name sarothamnine is suggested. Its 

 formula is given provisionally as Cj.H^^Nj, isomeric 

 with the base spartyrine resulting from the gentle 

 oxidation of sparteine. — Mile. Yvonne Dehorne and 

 L. Lutaud : Tectonic observations on the neighbour- 

 hood of Martigues (Bouches-du-Rh6ne). — F. X. 

 Skupienski : Sexuality in the Myxomycetes. — R. 

 Soueges : The embryogeny of the Liliaceae. Develop- 

 ment of the embryo in Anthericum ramosum. — M. 

 Folley : Technique of blood transfusion. — P. L. du 

 Noliy : A general equation for the law of normal 

 cicatrisation in surface wounds. 



Cape Town. 

 Royal Society of South Africa, May 15.— Dr. J. D. F. 

 Gilchrist, president, in the chair.— Ethel M. Doidge : 

 South African Perisporiaceae. III. Notes on four 

 species of Meliola hitherto unrecorded from South 

 Africa. The fungi considered in the paper are all from 

 Natal and the eastern part of the Cape Province, and 

 h^ve been identified from recent collections. — J. D. F. 

 Gilchrist: Reproduction of fishes in Table Bay. The 

 eggs and young of twenty-one species of fishes werp 

 procured in about sixty tow-nettings made at more or 

 less regular intervals throughout the year. Fourteen 

 of these were referred to known species. ' The eggs 

 procured and larvae hatched from them are described 

 and figured. The eggs of the sardine (5a rdina saga.x) 

 and of the anchovy (En^raulis capensis) indicate that 

 these fish are present in abundance, though as vet 

 not utilised for economic purposes. — W. A. Jolly : 

 Note on th'^ electrogram of the medulla oblongata.
