I90 SYNOPSIS 01? VETERINARY 



In the horse 1 to 1 34 ounce dissolved in 2j^ to 3 ozs. of 

 alcohol, injected into the jugular vein, produces anaesthesia almost 

 instantly, sufficient for experimental surgical operations. 



The anaesthesia is however evanescent in character, probably 

 more of a hypnosis than anaesthesia, as the subject frequently 

 shows signs of vague consciousness and benumbed sensation. 



The effects commonly last 2 or 3 days, terminating in death 



The above quantity should be injected slowly, as the rapid 

 introduction of the amount may cause sudden death. 



To increase the above quantity is to increase the probabilities 

 of immediate death. 



In the dog two doses of three grains each given about one- 

 half hour apart caused (in a cocker spaniel) sleep lasting 70 hours, 

 ending in' death ; the pulse beating strongly to the moment of 

 death. Other experiences of like character have occurred in the 

 experience of the writer.
