through papules and vesicles to pustules, and terminate in crusts, 

 that drop off leaving round bare spots. The vesicles may 

 appear locally or generally and may be discrete or confluent. 

 Sucking puppies, when attacked usually perish. 



In treatment the same hygienic measures are demanded as for 

 other animals, special care being required to keep the bowels and 

 kidneys acting in a healthy manner. Perfect cleanliness must be 

 secured, and uonstimulatiug easily digested food. Excessive 

 fever would demand tepid baths, cold sponging, or acetanilid, 

 and undue warmth, crowding and cold exposure must be alike 

 guarded against. 



In view of the alleged sources of the disease in man and sheep, 

 the strictest seclusion of the affected dog, in disinfected surround- 

 ings will become absolutely essential and when this cannot be 

 carried out he should be summarily destroyed. 



VESICULAR EXANTHEMA OF HORSES. 



Definition ; Vesicles usually on external genitals, with fever and infec-

Definition. An acute infectious disease, manifested by hyper- 

 thermia, hypersemia, and the formation usually on the external 

 generative organs of a crop of papules rapidly progressing to 

 vesicles, pustules and open sores, and attended by great local 

 irritation and itching. It runs a mild course and recovery ensues 

 spontaneously in about fifteen days. 



Causes. The disease is only known as a contagious affection, 

 propagated from animal to animal by breeding together, or by 

 using the same comb, brush or rubber, or by sucking, and in rare 

 cases by other accidental or experimental inoculations. To make 

 a successful inoculation the virus must be taken from the vesicles
