One of the most interesting evidences of the modern advance in
Brazil is the establishment near Sao Paulo of an institution
especially for the study of these poisonous snakes, so as to secure
antidotes to the poison and to develop enemies to the snakes
themselves. We wished to take into the interior with us some bottles
of the anti-venom serum, for on such an expedition there is always a
certain danger from snakes. On one of his trips Cherrie had lost a
native follower by snake-bite. The man was bitten while out alone in
the forest, and, although he reached camp, the poison was already
working in him, so that he could give no intelligible account of what
had occurred, and he died in a short time.
Poisonous snakes are of several different families, but the most
poisonous ones, those which are dangerous to man, belong to the two
great families of the colubrine snakes and the vipers. Most of the
colubrine snakes are entirely harmless, and are the common snakes that
we meet everywhere. But some of them, the cobras for instance, develop
into what are on the whole perhaps the most formidable of all snakes.
The only poisonous colubrine snakes in the New World are the ring-
snakes, the coral-snakes of the genus elaps, which are found from the
extreme southern United States southward to the Argentine.
