ductases: Emm. Pozzi-Escot. A claim for priority as 
against MM. Abelous and Aloy.—On the development of the 
vascular cryptogams: G. Chauveaud. The stem of the 
fern is constituted by the fusion of different parts, varying 
in number according to the level considered.—On the 
systematic position of the endophytes of orchids: I. Gallaud. 
Several authors have obtained from the roots of orchids 
fungi allied to Fusarium, but these would appear to have 
been external ; the endophytic forms obtained from the cells 
of the orchid are distinct from Fusarium.—The mycelium 
and conidian form of the Morel: Marin Motliard.—On the 
age of the human skeletons from the caves of Mentone: 
Marcellin Boule. The skeletons would appear to be of the 
same age as the deposits in which they were found, corre- 
sponding to the warm and most ancient period of the 
Quaternary. Other skeletons found in higher layers corre- 
spond to later periods of the same formation.—On a tunnel 
at Oupliz-Tsike, Transcaucasia: E. A. Martel.—Re- 
searches on the emission of the n-rays in certain phenomena 
of inhibition: Aug. Charpentier and Ed. Meyer.—The 
action of the radium radiations on colloids, hamoglobin, 
‘ferments, and the red corpuscles: Victor Henri and André 
iMayer. The B-rays, charged negatively, can precipitate 
;positive colloids, and are without action on negative 
‘colloids. Oxyhzmoglobin from the dog and the frog is 
‘transformed into methemoglobin and slowly precipitated ; 
carbonoxyhemoglobin remains unaltered. Ferments under 
the action of the rays slowly lose their activity, and after 
several days become completely inactive.—The emission of 
the #-rays in certain pathological cases: Gilbert Ballet.— 
The influence of the radium radiations on the toxicity of 
snake poison: C. Phisalix. The rays emitted by radium 
exercise an attenuating influence on snake poison, the in- 
tensity of which is a function of the time.—A physical and 
chemical method of recognising and measuring deep sub- 
marine currents: M. Thoulet.—Some new observations on 
phthiriosis in the vine: L. Mangin and P. Viala.—On 
the effects of grafting on the vine: Lucien Daniel and Ch. 
Laurent.
