SMALL-POX. 435 



SMALL-POX. 



Never having seen a case of this disease in the dog, I must be 

 content with extracting entire Mr. Youatt's description of it : — 



" In 1 809, there was observed, at the Eoyal Veterinary School 

 at Lyons, an eruptive malady among the dogs, to which they gave 

 the name of small-pox. It appeared to be propagated from dog 

 to dog by contagion. It was not difficult of cure ; and it quickly 

 disappeared when no other remedies were employed than mild 

 aperients and diaphoretics. A sheep was inoculated from one 

 of these dogs. There was a slight eruption of pustules formed on 

 the place of inoculation, but nowhere else ; nor was there the 

 least fever. 



" At another time, also, at the school at Lyons, a sheep died of 

 the regular sheep-pox. A part of the skin was fastened, during 

 four and twenty hours, on a healthy sheep, and the other part of 

 it on a dog, both of them being in apparent good health. No 

 effect was produced on the dog, but the sheep died of confluent 

 sheep-pox. 



" The essential symptoms of small-pox in dogs succeed each 

 other in the following order : the skin of the belly, the groin, and 

 the inside of the fore arm becomes of a redder colour than in its 

 natural state, and sprinkled with small red spots irregularly 

 rounded. They are sometimes isolated, sometimes clustered to- 

 .gether. The near approach of this eruption is announced by an 

 increase of fever. 



" On the second day the spots are larger, and the integument 

 is slightly tumefied at the centre of each. 



" On the third day the spots are generally enlarged, and the 

 skin is still more prominent at the centre.
