It may be supposed that although the species are numerous, the individuals of each kind are few.

By the kindness of Dr.Smith, I am enabled to show that the case is very different.

He informs me, that in latitude 24 degrees, in one day's march with the bullock-waggons, he saw, without wandering to any great distance on either side, between one hundred and one hundred and fifty rhinoceroses, which belonged to three species: the same day he saw several herds of giraffes, amounting together to nearly a hundred; and that, although no elephant was observed, yet they are found in this district.

At the distance of a little more than one hour's march from their place of encampment on the previous night, his party actually killed at one spot eight hippopotamuses, and saw many more.

In this same river there were likewise crocodiles.
