as the sole protection against Cochylis.—Mme. Marie 
Phisalix ; The independence of the toxic and vaccine 
properties in the cutaneous mucous secretion of 
Batrachians and some fishes.—L. Lapicque and R. 
Legendre: Relation between the diameter of nerve 
fibres and their functional rapidity.—Jacques Pellegrin ; 
The presence of deep-sea fishes on the Paris market. 
Owing to the increasing depths, up to 200 metres, at 
which trawling operations are mow carried out, 
numerous specimens of fish considered as very rare 
are occasionally sold for food in the Paris markets. 
A list of the rarer forms is given, including Ptery- 
combus brama, an archaic fish not represented in the 
Paris Museum.—J. Athanasiu and J. Dragoiu: The 
aérial capillaries of the muscular fibres in insects.—H. 
Dominici and M. Ostrovsky : The action of the diffusible 
poisons of the Koch bacillus upon normal tissues. 
The results of these experiments invalidate the com- 
monly accepted theory with regard to the pathogeny 
of the lesions caused by the Koch bacillus.—M. Javillier 
and Mme. H. Tchernoroutsky : The comparative influ- 
ence of zinc, cadmium, and glucinum on the growth 
of some Hypomycetes. Three moulds were examined 
Poecilomyces varioti, Penicillium caseicolum, and 
Penicillium glaucum—and in each case there was 
marked catalytic action of zinc salts in stimulating 
growth. Cadmium showed a similar but much 
smaller activity, whilst glucinum salts are inert.—Ph. 
Glangeaud : The dislocations and the amethyst-quartz 
lodes of Livradois. The oid extension of the coal 
basin of Brassac.—G. Vasseur: New palzontological 
discoveries in the upper Aquitanian in the neighbour- 
hood of Laugnac (Lot-et-Garonne). This region is 
remarkably rich in fossil vertebrates.—Ph. Flajolet : 
Perturbations of the magnetic declination at Lyons 
(Saint Genis Laval) during the third quarter of 1913.
