REMAKKS. 



Injected intravenously dialysis-venom-globulin from the dried 

 venom of the Crotalus adamanteus. 



Injected intravenously 0.0017 gram dialysis-venom-globulin 

 from the dried venom of the Crotalus adamanteus. 



Clot formed in canula. 

 Injected 0.0034 gram. 



Struggles. 



The Actions of the Venom Globulins on Animals with Cut Pneumogastric 

 Nerves. — In five experiments on animals with cut pneumogastric nerves — one with 

 the water-venom-globulin, two with copper-venom-globulin, one with dialysis-venom- 

 globidin (all from the Crotalus adamanteus), and one with the water-venom-globulin 

 of the Cobra — there was a tendency to a lowered pulse-rate, although in one 

 experiment there was a primary increase, and in another a slight increase above 

 the healthy number after repeated injections. The effects were generally less 

 than in normal animal.
