perfcies of daboia-venom was destroyed at a 

 temperature of 100° C, though the venom still 

 retained its poisonous power. As regards the 

 intensity of the venoms, Drs. Weir Mitchell and 

 Reichart express an opinion which corresponds 

 with that I have already given. They say, 

 " beyond a doubt, cobra- venom is the most intense 

 in its poisonous power, the venom of the cop- 

 perhead next,' then the moccasin and rattle- 

 snake.'' The most important part of their paper 

 is that in which they describe the chemical 

 analysis of the venoms. They succeeded in 

 isolating three proteids, viz. : — 



Venom — Peptone 

 „ Globulin 

 „ Albumin. 



The first two they say are poisonous, and the 

 last innocent. According to them the venom- 

 peptone is a " putrefacient;" and the venom- 

 globulin, a much more fatal poison, which 

 probably attacks the respiratory centres and 

 destroys the ppwer of the blood to clot.
