of the stomach, and we have rarely exam-

in large numbers and in such cases are no 
doubt a positive injury. 
Causes. — During the summer months 
it is quite a common thing to see the 
bot-fly or gadfly annoying the horse. The 
object of the fly is to deposit its eggs 
upon the hairs of the under portion of the 
head and neck and about the legs. When 
biting or rubbing his legs he takes these 
into his mouth, from which they pass 
into the stomach. Here they become at- 
tached to the lining membrane and de- 
velop until spring, when they let go their 
hold and pass through the bowels with 
the manure, after which they rapidly 
develop into the full-grown bot-fly. 
Symptoms. — The first noticeable symp- 
tom is that he is not doing well, although 
he has a ravenous appetite. What he
