THE ACTION OF VENOMS UPON RESPIRATION. 



129 



The Action of Venom Globulins on the Respiration of Animals in whiclv the 

 Pueumogast ric Nerves were Cut. Two experiments were made on animals with 

 cut pneumogastric nerves : one with the dialysis-venom-globulin, and one with the 

 copper-venom-ylobulin, both from the Crotalus adamanteus. 



In neither experiment was there an increase in the respirations ; these results 

 being in accord with the experiments made with pure venom. 



Experiment No. 23. 



REMARKS. 



Pneumogastric nerves previously cut. Injected hypo- 

 dennically the dialysis-venom-gJobulin from 0.015 

 grain dried venom of the Crotalus adamanteus. 



Struggles. 



Injected dialysis-venom-globulin from 0.06 gram/ 



Struggles. 



Respiration ceased ; heart beats feebly ; blood remains 

 incoagulable; great ecchymoses in abdominal viscera. 



REMARKS. 



Pneumogastric nerves previously cut. Injected intra- 

 venously the copper-venom-globulin from 0.015 gram 

 dried venom of the Crotalus adamanteus. 



Injected copper-venom-globulin from 0.03 gram dried 

 venom in two doses. 



j Struggles with very irregular breathing followed by 

 | gasping respiration,.
