chlorine and bromine. Details are given of the appli- 

 cation of a method described in a previous note, based 

 on the use of fuchsine decolorised with sulphuric acid. 

 Dealinjj with such small quantities of bromine as are 

 found in "certain natural waters, the method can be 

 applied quantitatively ; it is more delicate and rapid 

 than the methods in current use. — J. B. Senderens and 

 Jean Aboulenc : The ethereal salts derived from the 

 cyclanols and the acids of the fatty series. Starting 

 with the six lower members of the fatty 

 acids and the alcohols cyciohexanol and the 

 three isomeric methylcycZohexanols, twenty-four 

 esters have been prepared by the catalytic 

 method described in an earlier paper. The physical 

 properties of these esters are tabulated. — Jacques 

 Duclaux : The specific heat of bodies at low tempera- 

 tures. It is known that the specific heat of most 

 substances diminishes rapidly at low temperatures ; 

 the author discusses the hypothesis that this reduction 

 of specific heat is due to increasing polymerisation. — 

 Daniel Berthelot and Henri Gaudechon : The photolysis 

 of saccharose by the ultra-violet rays. A study of the 

 effect of the wave-length of the ultra-violet light on 

 the chemical changes produced. — R. Fosse : The trans- 

 formation of an alcohol into the sulphide of peroxide 

 by the action of sulphuretted hydrogen and of hydrogen 

 peroxide. — J. Tchougaeff and B. Orelkine : Some com- 

 plex compounds of platinous chloride with amino- 

 acetal.^ — R. de Litardiere : The formation of hetero- 

 typical chromosomes in Polypodiuni vulgare. — Maurice 

 Durandard : The combined influence of temperature 

 and of the medium on the development of Mucor 

 Roiixii. — Marc Bridel : The presence of gentiopicrin 

 in Swertia perennis. The biochemical examination 

 has shown that this plant contains a glucoside 

 hydrolysable by emulsin ; this glucoside has been 

 isolated in a pure state and identified with gentio- 

 picrin. — J. WolH : The biochemical function of the 

 peroxydases in the transformation of orcin into orcein. 

 — Pierre Bonnier : The late awakening of the bulbar 

 centres. The bulbar nervous centres in newly born 

 children often require stimulation to start their action. 

 This defect can be remedied by a very slight cauterisa- 

 tion of the nasal mucous membrane. Several success- 

 ful cases of the application of this treatment are cited. 

 — Jules Aniar : . the laws of work; experiments on 

 filing. A study of the work expended by a man 

 during the operation of filing brass, with a statement 

 of the best conditions for the maximum yield for 

 given expenditure of muscular effort. — Charles NicoUe, 

 .■\ Conor, and E. Conseil : Intravenous inoculation of 

 dead typhoid bacilli in man. The treatment is marked 

 by the absence of any reaction or local pain, and by 

 the production in the system of a notable amount of 

 the tvnhoid antibody. — Auguste Lumiere and Jean 

 Chevrotier : The polyvalence of the anti-typhoid sera. — 

 A. Marie and L^on MacAuliBe : The study and measure- 

 ment of 100 French tramps. — De Montessus de 

 Ballore : An earthquake of epirogenic origin probable 

 in the neighbourhood of Michigan and Wisconsin. — 

 M. Bouree : The vertical migration of bathypelagic
