NON-VENOMOUS SNAKES. 381 
I injected six drops of Puff Adder venom into a large Mole 
snake, four feet six inches long. The injection was made in the 
middle part of the back under the skin. The Mole snake survived 
three days and died. Another lived nine days. If a large dose 
(six drops) is injected right into the abdominal cavity, it is in- 
variably fatal. 
A Mole snake was also bitten by a variegated variety of Boom- 
slang in the muscles of the back a few inches above the tail, on 
a spot from which the scales had been scraped off. The Boom- 
slang was allowed to hold on for three or four minutes and worry 
the flesh. The venom shed on the skin was then scraped up and 
rubbed into a cut in the back of the Mole snake. No poisonous 
effects followed.
