OBSERVATIONS. 
It is pretended that the bite of the Bora does not prove 
mortal till after 10 or 12 days, but that eruptions in different 
parts of the body soon follow the introduction of the poison 
into the blood. Nothing in the snake seems to warrant a 
belief that it is poisonous. 
Innumerable varieties and species of this genus abound in 
South America, some individuals attaining to an enormous 
size. One was killed on the head waters of the River Amazon 
30 feet in length, and more: than 3 feet in diameter; and an 
English nobleman saw one, just after it was killed, on the 
island of Manilla, which measured over 31 feet long, and 
more than 39 inches in diameter. | 
The number of species, at present classified, is 13, com- 
posed of 16 varieties.
