158 THE LAND-MAKKS OF 



This had resulted in the separation from snake- 

 venoms of their proteid poisons, the one like a 

 globulin, attacking respiratory centres, and pre- 

 venting coagulum ; a second resembling albumin, 

 and being probably innocuous; a third like 

 peptone, and being a " putrefactive poison." With 

 some of these results I agree, but not with all. 

 Dr. Wolfenden sums up the results of his in- 

 vestigations, but he remarks that they must not 

 yet be regarded as complete. He says there are 

 two poisonous elements in cobra-venom, viz. — 



1. Cobra globulin- venom, 



2. Cobra albumin," 



and that they probably exist in different propor- 

 tions in different secretions. What other albumins 

 are present, are not of the importance these two 

 are. The globulin- venom poisons the respiratory 

 centre, producing no paralysis of muscle; the cobra- 

 albumin venom does not affect the respiratory 

 centre, but produces marked and progressive 

 motor paralysis. Wolfenden points out further 

 that "globulin-venom is slower in its action 

 than the albumin-venom, and a longer period 

 often elapses after the injection, before symp- 

 toms supervene and terminate life. The globulin 

 is very deadly, and when once the symptoms
