order that the magnitude of the changes both in the kennel 

 as well as in the laboratory may be realized. 



Usually the dog would be lying asleep when the room was 

 entered and would come slowly out of his bed to stand wag- 

 ging his tail. He did not retreat or move when patted or 

 when the leash was now put on, but walked slowly and quite 

 readily beside the attendant. There was no crouching or 

 urinating. When taken to the laboratory and led to the 

 platform, he stood perfectly still, head held low, and when 

 left alone in the room sat down calmly, and after a few 

 minutes lay down. In the majority of cases, no conditioned 

 reaction was observed when the Met. 120 was sounded. In a 

 few cases there was an abortive response. At the stimulus 

 he raised his head, looked to the side and rose to his feet. 

 There was no further reaction. Even when the shock was 

 applied there was often no reaction.

The behavior was studied for 2 days with the dog in this 

 condition. The animal was then given Eschatin subcutaneous- 

 ly, 21 cc. daily in two 10.5 cc. doses morning and afternoon, 

 for 3 days. Great improvement in behavior in general was 

 noticed almost at once and both the efficiency and the magni- 

 tude of the C-R were improved to a very noticeable extent. 



As indicated in table 29, the efficiency of the response was 

 unaffected in the first post-operative period (100 per cent) 

 but in the second, 21 days after the operation, it was greatly 

 lowered (100 per cent to 38 per cent). In the third period 

 during the Eschatin therapy the level was restored to normal 

 (100 per cent).
