330 DOGS : THEIR MANAGEMENT.

 tion which, when properly undertaken, is remarkably- 

 easy and simple. I believe I was the first practitioner

 male is to be relieved.

 and the outer surface moistened with olive oil.

 length, 4 and 5 ; the longest, Nos. 6, 7, and 8.

 in a position such as the operator may think most advan-
