SYNOPSIS OP VETERINARY CONTINENTAL JOURNALS. 531 
nummular form which it affects at first may indicate its 
cause as a parasitic cryptogam, it being, then, a humiclpara¬ 
sitic eczema. 
(Eczema is commonly considered to be non-contagious ; 
nevertheless, it seems to be sometimes associated with para¬ 
sites. Zurn found the yeast fungus in eczematous lesions of 
cattle of distilleries. We can in such cases understand how 
transmission could take place, and it seems, indeed, that, as 
in M. Collin’s cases, the disease was transmissible from one 
animal to another. M. Cornevin and I (M. Violet) believe 
we have found in the centre of the crusts forwarded by 
M. Collin a fungus of which we have been unable to deter¬ 
mine the species. Always we failed in attempts to sow the 
fungus, with the necessary precautions, on cattle; but 
these experiments were unsuccessful, perhaps, because of 
tbe age of the parasite.) 
We have examined the crusts with the micrograph of 
Wassy, but found nothing definite, probably since we are not 
accustomed to this form of research. The disease has some 
character in common with herpes tonsurans. Thus, it affects 
a circular form, and has a tendency to spread and propagate ; 
but these are then only points of resemblance. Herpes ton¬ 
surans, which I had occasion to observe in September and 
October, 1879, on more than three hundred animals, differs 
from the disease of the cows of Brachay by its more marked 
benignity, the nature of the secretion of the dermis, &c. 
These maladies are very distinct, and confusion is hardly 
possible. The owner was able to give us no further infor¬ 
mation on the origin and nature of the disease. The animals 
were stall fed, and had been given green lucern and good- 
quality hay of natural pasture. The persons attending the 
cattle were not affected with any disease of the skin. 
Treatment was necessarily such as best accorded with our 
opinion of the nature of the disease. Since this was parasitic 
and contagious, all such measures as would best serve to 
prevent its propagation to other animals and its spread over 
those already affected were adopted. The cow with only a 
patch on the side was removed from the infected stable and 
isolated ; the patient more seriously affected was left in its 
usual place. We then disinfected the stable by destroying 
all the parasites and their germs on all the objects on which 
they had been deposited. After the dung had been removed 
the place was thoroughly washed down, also the walls and 
mangers dressed with alkaline lye-washes, and subsequently 
whitened with lime. These precautions were all the more 
necessary because the animal was left in the place, and thus
