of snakes during a
space of seven years; and in other places where I made the same inquiry,
the casualties were much less in proportion to the numbers."

"Is the boa constrictor found in this part of Africa?"

"Not so far south as we now are, but it is a few degrees more to the
northward. I have never seen it, but I believe there is no doubt of its
existence."

"The South American Indians have a very subtile poison with which they
kill their game. Are you aware, Swinton, of its nature? Is it like the
Bushmen's poison?"

"I know the poison well; it was brought over by Mr Waterton, whose
amusing works you may have read. It is called the wourali poison, and
is said to be extracted from a sort of creeping vine which grows in the
country. The natives, however, add the poison of snakes to the extract;
and the preparation is certainly very fatal, as I can bear witness to."

"Have you ever seen it tried?"

"Yes, I have tried it myself. When I was in Italy I became acquainted
with Mr W, and he gave two or three of us, who were living together, a
small quantity, not much more than two grains of mustard-seed in size.
We purchased a young mule to make the experiment upon; an incision was
made in its shoulder, and the poison inserted under the skin. I think
in about six or seven minutes the animal was dead. Mr W said that the
effects would have been more instantaneous, if the virtue of the poison
had not somewhat deteriorated from its having been kept so long."

"The wourali poison only acts upon the nerves, I believe?" said the
Major.

"Only upon the nerves; and although so fatal, if immediate means are
resorted to, a person who is apparently dead from it may be brought to
life again by the same process as is usual in the recovery of drowned or
suffocated people. A donkey upon which the poison had acted was
restored in this manner, and for the remainder of his days permitted to
run in Sir Joseph Banks's park. But the poison of snakes acts upon the
blood, and therefore occasions death without remedy."

"But there are remedies, I believe, for even the most fatal poisons?"

"Yes, in his provident mercy God has been pleased to furnish remedies at
hand, and where the snake exists the remedy is to be found. The
rattle-snake root is a cure, if taken and applied immediately; and it is
well known that the ichneumon when bitten by the cobra capella, in his
attack upon it, will hasten to a particular herb and eat it imme
