soluble in organic solvents. The corresponding amide crystal- 
lises in white, silky needles melting at 115°.—Fluorine in mineral 
waters, by M. Charles Lepierre. It is maintained, in opposition 
to M. Parmentier, that minute traces of fluorides have been de- 
tected in many natural waters, and that considerable quantities 
—equivalent to 10 or 12 milligrammes of fluorine per litre—are 
present in the mineral water of Gerez (North Portugal), which 
is much esteemed for its efficacy in diseases of the liver.—On 
the genesis of the iron ores of Lorraine, by M. P. Villain. 
Arguments are brought forward in support of the theory that the 
oolitic ore of Lorraine is a littoral deposit, the mineralisation of 
which has been effected by the action of hot springs in the bed 
of an ancient sea.—On a parasitic fungus in cancerous affections, 
by M. J. Chevalier. The author has succeeded in isolating 
what appears to be a specific fungus from cancerous tumours, 
from the blood of patients, and from the air of hospitals. A 
temperature of from 28° to 35° is most favourable to its growth, 
but it is highly resistant, the spores not being destroyed by ten 
minutes’ heating at 100°, The parasite exists in the form of 
conidia, a mycelium, or spherules, according to the stage of de- 
velopment and the medium employed. Its specific character is 
confirmed by the results of inoculation experiments, but further 
study will be required before the causal connection between the 
parasite and cancerous affections is definitely established.
