 indicates — is to make the opening through the thin abdominal wall. 



(3) Ecraseur. The most satisfactory eeraseur yet ottered to the veterin-

 strong, well constructed and its design ideal. The advantages of this 

 instrument over others consist of an arrangement b.y which, with the 

 thumb and finger of one hand (the other hand left free), the ecraseur 

 can be held, and the slack of the chain taken up at once without drawing

 due to imperfect or careless ad.justment, which often occurs with other 

 ecraseurs. It is also easj- to clean and sterilize, as it can be taken apart 

 without the aid of a screwdriver in a few seconds' time, by a half tuni 

 of the collar near the handle. ]t is made with or without the improved 

 head. The one with the improved head is much to be preferred.
