[May 4, 1899 
by the apparatus are given, showing the curves of the tricuspid, 
mitral and aortic valves.—New observations of the planet EL 
(Coggia, March 31, 1899), made at the Observatory of Marseilles 
with the 26cm. equatorial, by M. E. Stéphan.—Observations of 
the new Coggia planet (EL), made at the Observatory of Algiers 
with the 31°6 cm. equatorial, by M. Rambaud.—On the sterilis- 
ation of potable waters by ozone on the industrial scale, by MM. 
Marmier and Abraham. The apparatus was set up at Lille. After 
the water had passed through the ozonising column, all sapro- 
phytic and pathogenic organisms were destroyed with the excep- 
tion of some spores of Bacillus suhtilis ; this organism also offering 
considerable resistance to all the usual methods of sterilisation. — 
—On furfuryl alcohol, by M. G. André. Specimens of this alcohol 
prepared by different methods for calorimetric determinations 
differed considerably in purity, the method of Wissel and Tollens 
being the only one yielding a pure substance.—Osazones from 
oxycelluloses, by M. Léo Vignon. Cotton wool was oxidised in 
various ways to oxycelluloses, and these heated with phenyl- 
hydrazine in acetic acid solution. The osazones formed were 
not constant in composition. —On the sugar of maize stems, by 
MM. C. Istrati and G. Gittinger. Measurements of the reducing 
power before and after inversion of the juice from the stems of 
sixteen varieties of maize. —Remarks on a_ preceding communi- 
cation “On the pathogenic agent of hydrophobia,” by M. E. 
Puscariu. The amylaceous formations observed in the central 
nervous system of animals who died from hydrophobia have 
been found in cases of general paralysis, abscess of the brain 
and in diphtheric paralysis. Hence the view previously put for- 
ward, that these formations are of parasitic origin and peculiar to 
hydrophobia, is erroneous.—On ‘the reducing power of the 
tissues: the blood, by M. Henri Hélier.—On a ratio existing 
between intraorganic oxidations and the production of kinetic 
energy in the organism, by M. Alexandre Poehl.—The microbes 
of flowers, by M. Domingos Freire. Numerous species of 
organisms have been found in flowers, including the pathogenic 
Bacillus pyocyaneus.—On the wines obtained by the preliminary 
healing of the vintage, by M. A. Rosenstiehl. The preliminary 
sterilisation of the must by heating and the subsequent introduc- 
tion of suitable yeasts, in all the instances tried, gave a wine 
superior to that obtained by the traditional methods.—The 
specific characters of the fungus of Pélyriasis versicolor, by M. 
Paul Vuillemin. —Researches on the mineral elements, especially 
iron, in the human fcetus, by M. L. Hugounenq.—The form- 
ation of the egg in Myriothela and Tubularia, by M. Alphonse 
Labbé.—Tangential increase of the pericycle, by M. Henri 
Devaux.—Discussion of barometric observations, by M. A. 
/Poincaré.
