THEIE NATUEE AND EFFECTS. 65 



blood than that found in cobra-bite ; a circumstance 

 that is due to the greater power daboia-poison has in 

 causing the contents of the blood-vessels to transude 

 through their walls. However, if a dissection of a 

 daboia-bite be made about three minutes after its inflic- 

 tion, a circle of injected vessels with a pinkish effusion 

 within the meshes of the areolar tissue will be found, 

 sufficient to show the real nature of the process that is 

 commencing. The presence, however, of daboia-poison 

 imparts, so to speak, a " specific " character to the 

 inflammation in the large amount of blood-material in 

 the effusion. The characteristic changes are quite as 

 rapid in occurring as in cobra-bite ; if, indeed, they are 

 not more so, and they are of precisely the same nature, 

 the only difference being in regard to degree, I'hey are 

 invariably followed, should the animal live, with slough- 

 ing and suppuratidn, and are equally .valuable as evidence 

 of poisoning with those of cobra-bite. 



Action of Daboia-Poison on the Nervous System. 



Enough has already been said to show that there are 

 considerable differences in the action of daboia and 

 cobra-poisons on the nervous system. Daboia-poison 

 commences its action by producing convulsions. It is 

 true that the animal may escape them, through an 

 insuffiftient quandty of poison being injected. Now, 

 these convulsions in no way, depend upon a large
