THEIE NATURE AND EFFECTS. 153 



six cubic centimetres of water, was injected through the 

 cannula of the syringe which had not been removed. 



12.45 P.M. Salivation. 



4.15 p.m. Not able to stand. Respiration very faint. 

 Artificial respiration by bellows and cannula through 

 the tracheal opening commenced. 



5.3 P.M. Breathing by artificial respiration almost 

 entirely. 



5.50 P.M. Natural respiration stronger. 



fi.lO P.M. Artificial respiration stopped, as the 

 natural was sufficient to support life. 



10.10 P.M. Able to get off couch and walk about. 



The animal completely recovered. 



Here, through the alkali having been injected through 

 the same channel as the poison, and soon after it, but 

 a small quantity of poison was absorbed, artificial respi- 

 ration was resorted to before natural respiration had 

 stopped and only to aid it. The artificial respiration 

 was constantly interrupted, to see that the natural respira- 

 tion was still performed, so that all that was done was 

 to assist the failing respiratory powers, not to supersede 

 them, and the animal's life was saved. A result like 

 !his cannot be often looked for under the natural con- 

 ditions of poisoning, as every detail was here arranged 

 beforehand. Great importance must be attached to the 

 fact that the tracheotomy was performed previously. 

 Butgthe case shows that every efi'ort should be made to 

 assist the failing respiratory powers. When natural
