 a geologist, viewing such an enormous collection of

His discerning eye immediately connected these 

 modern fatalities with those that had occurred ages 

 in the past, and saw a possible explanation of the 

 great deposits of fossil bones found to-day mingled 

 in such an inexplicable confusion. 



In coming down the Parana, our young naturalist, 

 who was inclined to wander ashore and visit the 

 many islands which abounded, was warned to be on 

 his guard against the jaguar, which was common 

 here. The canebrakes of the river were the favourite 

 haunts of the American tiger, and its tracks were 

 found everywhere. When their natural food is 

 scarce they do not hesitate to attack man. A sailor 

 fought with one on the deck of a vessel, losing his 

 arm in the contest ; while a few years previous to 

 Darwin's visit, a " man-eater " found its way into the
