530 SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 
purulent, and hardened more slowly, giving rise to soft and 
gelatinous crusts. This stage of the disease lasted three or 
four days. On elevation of the crusts the dermis was found 
to be of a violet-red colour and covered with an abundant 
serosity, especially where the hairs are erect and aggluti¬ 
nated ; the subepidermic network is highly injected; softening 
of the neighbouring epidermis and the formation of fresh 
vesicles caused extension of the morbid state. In this cow, 
as in the heifer, the disease progressed rapidly and became 
generalised; the regions bordering on the parts previously 
affected became involved ; thus, from the udder it extended to 
the belly, and then on the surfaces of the thighs. Also it 
was found in fresh situations, as the sides and back, espe¬ 
cially towards the left, that is, on the side which came in 
contact with the heifer. Here spots occurred in which the 
hairs were erect and agglutinated by a secreted liquid; and 
if in these positions We detached with the finger the crusts 
commencing to form the hair separated with them, and 
denuded patches, of a circular form, varying in size from that 
of a one-franc to a two-franc piece, resulted, the exposed 
dermis being hypereemic and secreting an abundant serosity. 
It is evidently the same disease which affected the heifer. 
As for the second cow placed to the right of the animal 
just described and separated by it from the heifer, it showed 
also on the left side, behind the shoulder, a patch of a 
circular form and of the size of a five-franc piece, with hairs 
erect and agglutinated. On raising the crust as it was 
forming we exposed the dermis, of a reddish-violet colour, 
and covered with a clear serosity. In these three beasts the 
disease presented exactly the same characters. At the com¬ 
mencement there are the circular patches formed by an 
agglomeration of vesicles, these soon running together, and 
the skin in the corresponding parts sweating in abundance. 
Softening of the neighbouring epidermis and the formation 
of fresh vesicles caused increased extension of the disease. 
Under the influence of heat the disease increased in activity 
and soon became generalised. The secreted liquid agglu¬ 
tinated the hairs, hardened, and produced crusts resembling 
dried meal. The dermis, when exposed, is found to be of a 
reddish violet colour, and to continue to secrete. A fairlv 
acute itching is marked from the commencement. Some 
days afterwards the secreted liquid is more abundant, 
very fluid, and does not harden ; it consequently moistens 
the hairs which are erect, and partly suppurates and rapidly 
undergoes ammoniacal and putrid fermentations. It is 
difficult to determine the exact nature of this disorder. The
