difference in the action of cobra and daboia 

 veno m as follows : — 



Cobra-Poison. 



1. The regular course ia 

 slowly advancing general 

 paralysis coming on after an 

 interval without symptoms, 

 with especial paralysis of 

 the lips, tongue, larynx and 

 pharynx, and complete de- 

 fitruction of the respiratory 

 function. Death ia often 

 attended by conyalsions, 

 which depend on asphyxia. 



2. Very quickly destroys 

 respiration. After slight 

 acceleration there is slowing, 

 and excursus is lessened. 



Daboia-Poison. 



1. Commencesitsaction 

 by producing violent gener- 

 al convulsions, which often 

 terminate fatally, or may 

 be followed immediately 

 by paralysis and death, or 

 may also be recovered 

 from paralysis and death 

 following later. 



The paralysis is general, 

 and lasts a considerable 

 time after respiration is 

 extinguished. No special 

 paralysis of lips, tongue, 

 larynx and pharynx. 



2. At first quickens the 

 respiration very much 

 mora than cobra-poison 

 does, and the lessening of 

 the excursus and the re- 

 tardation of the respiratory 

 movements do not occur 

 so soon.
