and truculent, striking right and left and biting freely on the
smallest provocation--this is the case with the species of which the
doctor had previously placed a specimen on the table. Moreover, many
snakes, some entirely harmless and some vicious ones, are so nervous
and uneasy that it is with the greatest difficulty they can be induced
to eat in captivity, and the slightest disturbance or interference
will prevent their eating. There are other snakes, however, of which
the mussurama is perhaps the best example, which are very good
captives, and at the same time very fearless, showing a complete
indifference not only to being observed but to being handled when they
are feeding.

There is in the United States a beautiful and attractive snake, the
king-snake, with much the same habits as the mussurama. It is friendly
toward mankind, and not poisonous, so that it can be handled freely.
It feeds on other serpents, and will kill a rattlesnake as big as
itself, being immune to the rattlesnake venom. Mr. Ditmars, of the
Bronx Zoo, has made many interesting experiments with these king-
snakes. I have had them in my own possession. They are good-natured
and can generally be handled with impunity, but I have known them to
bite, whereas Doctor Brazil informed me that it was almost impossible
to make the mussurama bite a man. The king-snake will feed greedily on
other snakes in the presence of man--I knew of one case where it
partly swallowed another snake while both were in a small boy's
pocket. It is immune to viper poison but it is not immune to colubrine
poison. A couple of years ago I was informed of a case where one of
these king-snakes was put into an enclosure with an Indian snake-
eating cobra or hamadryad of about the same size. It killed the cobra
but made no effort to swallow it, and very soon showed the effects of
the cobra poison. I believe it afterward died, but unfortunately I
