THEIR NATURE AND EFFECTS.

blood-poisoning little, if at all, less dangerous than the primary symptoms. We have, in addition, the greater local mischief caused by daboia-poison, and the greater power it has of destroying the coagulability of the blood.

The physiological properties of dahoia-poison undergo great change by its being heated to 100° C. in solution, losing the power of producing primary convulsions, whereas cobra-poison remains unaltered.

Daboia-poison kills birds at once in convulsions, whereas with cobra-poison — unless the poison has been directly injected into the circulation — death occurs only after paralysis.

Lastly, amphibia recover from an amount of daboia-poison that would be necessarily fatal in the case of cobra-poison.
