The jaguar, however, has long been known not only to be a dangerous
foe when itself attacked, but also now and then to become a man-eater.
Therefore the instances of such attacks furnished me are of merely
corroborative value.

In the excellent zoological gardens at Buenos Aires the curator,
Doctor Onelli, a naturalist of note, showed us a big male jaguar which
had been trapped in the Chaco, where it had already begun a career as
a man-eater, having killed three persons. They were killed, and two of
them were eaten; the animal was trapped, in consequence of the alarm
excited by the death of his third victim. This jaguar was very savage;
whereas a young jaguar, which was in a cage with a young tiger, was
playful and friendly, as was also the case with the young tiger. On my
trip to visit La Plata Museum I was accompanied by Captain Vicente
Montes, of the Argentine Navy, an accomplished officer of scientific
attainments. He had at one time been engaged on a survey of the
boundary between the Argentine and Parana and Brazil. They had a
quantity of dried beef in camp. On several occasions a jaguar came
into camp after this dried beef. Finally they succeeded in protecting
it so that he could not reach it. The result, however, was disastrous.
On the next occasion that he visited camp, at midnight, he seized a
man. Everybody was asleep at the time, and the jaguar came in so
noiselessly as to elude the vigilance of the dogs. As he seized the
man, the latter gave one yell, but the next moment was killed, the
jaguar driving his fangs through the man's skull into the brain. There
was a scene of uproar and confusion, and the jaguar was forced to drop
his prey and flee into the woods. Next morning they followed him with
the dogs, and finally killed him. He was a large male, in first-class
condition. The only features of note about these two incidents was
