HUMAN AND ANIMAL VARIOLAS.

was supposed to have cured a good number. No mention is made 
of small-pox among people. In 1878, according to the Veterinary 
Journal (vol. vii., p. 210), there was a serious outbreak of swine¬ 
pox in many localities in the Hernals and Baden districts. It 
first appeared among swine of Hungarian origin imported from 
Odenburg, and from them was communicated to the native herds. 
The mortality was unusually great. The conditions attending the 
appearance, course and termination of the disease, were precisely 
analogous to those which obtain in sheep-pox, and the veterinary 
sanitary measures in force for the latter were adopted successfully 
for the swine-pox. No mention is made of sheep-pox, cow-pox 
or small-pox prevailing at the time. 
Doa-Pox. 
In the dog, variola has been observed and described by many 
authorities, and is, in fact, a comparatively well-known disease to 
veterinarians. It chiefly attacks young dogs, though old ones are 
not exempted, and one attack affords immunity from others. 
Variola canina commences, as in other animals, wfith fever, which 
continues for two or three days, and is then followed by the 
appearance over a large surface of the body, though rarely on 
the back or sides, of red points resembling flea-bites, which in a 
very short time are the seat of papules, and then of vesicles. 
The contents of these become purulent, and Anally dry into a 
crust, which, being shed, leaves a marked cicatrix. In the dog, 
as in sheep, goat and pig, the disease does not always maintain 
the same form ; it is sometimes epizootic, and is benignant or 
malignant. Young dogs nearly always succumb, and a necropsy 
often reveals the presence of variolous pustules on the mucous 
membrane of the respiratory and digestive organs. The disease 
does not appear to be very infectious, though it is contagious and 
inoculable. It appears to lie communicable to mankind, for 
Bosenroth* saw the disease affecting dogs around the nose, face, 
eyes and back, and the attendant became infected. The dog does 
not appear to be very susceptible to the variolse of other animals, 
nor yet to that of man. I can find few instances mentioned in 
*Magazin fur Tkierlieilkunde, 1860, p. 341.
