Lesson Twenty Part three Snake poison
What are the two different ways in which snake posion acts?
Vipers (adders) and rattlesnakes manufacure the blood poison, which is known as haemolytic. Both posions are unpleasant , but by far, the more unpleasant is the blood poison. It is said the nerve poison is the more primitive of the two, then 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 aganist man, but for use against prays such as rats and mice, and the effects on these of viperine posion is almost immediate.
