Lesson 20-3 Snake poison

Vipers (adders) and rattlesnakes manufacture the blood poison, which is known as

haemolytic. Both poisons are unpleasant, but by far the more unpleasant is the blood

poison. It is said that the nerve poison is the more primitive of the two, that the blood

poison is, so to speak, a newer product from an improved formula. Be that as it may,

the nerve poison does its business with man far more quickly than the blood poison.

This, however, means nothing. Snakes did not acquire their poison for use against man

but for use against prey such as rats and mice, and the effects on these of viperine poison

is almost immediate.
