MAMMALIA — SLOTH. 265 



error in nature ; for, even in the largest animals, and those whose bodies 

 are relatively longer than they are thick, not one of them is found to have 

 so many. The elephant has only forty, the dog twenty-six, and the human 

 species twenty-four, &:c. This difference in the construction of the unau

 ones, which are the causes of the others. These animals inhabit South 

 America, and are especially numerous in Brazil and Guiana.

 have been given of the sloth, you would probably suspect that no naturalist 

 had actually gone into the wilds with the fixed determination to find him 

 out and examine his haunts, and see whether nature has committed any 

 blunder in the formation of this extraordinary creature, which appears to us 

 so forlorn and miserable, so ill put together, and so totally unfit to enjoy the
