EXPERIMENT IL 



October 3, at 12 o'clock. Two grains of acetate of 

 morphia were injected into the external jugular vein. 



12.3. Pupils contracting. 



12.4J. The dog suddenly jumped up and began 

 running about, and apparently frightened at us. 



12.15. Injected another two grains. 



12.23. Dog much excited, whining whenever he is 

 disturbed, and dragging the hind legs a little. 



1 2.34. Two more grains injected. 



12.37.- -Running about excitedly. 



Result. No coma was induced, and he gradually 

 recovered. 



COMMENT. 



I did not inject ammonia in this case, as I wanted 

 to get him comatose first ; failing this, I allowed him 

 to recover. 



EXPERIMENT III. 



Sixteen grains of acetate of morphia were injected 

 into the peritoneal cavity of a dog. 



Result. Soon became comatose. 



I then injected liq. ammonise into a vein. 



Result. He quickly became conscious, and soon 

 recovered perfectly. 



EXPERIMENT IV. 



I now determined to leave the ammonia alone, and 

 see how much morphia a dog could stand without any 

 remedy at all : 



2J grains injected into the jugular. 

 12 grains subcutaneously. 

 30 grains given by the mouth. 



grains within an hour and a halt
