This will give an average (from the above estimates) of 2.7 of a ton for the ten largest herbivorous animals of Southern Africa.

In South America, allowing 1200 pounds for the two tapirs together, 550 for the guanaco and vicuna, 500 for three deer, 300 for the capybara, peccari, and a monkey, we shall have an average of 250 pounds, which I believe is overstating the result.

The ratio will therefore be as 6048 to 250, or 24 to 1, for the ten largest animals from the two continents.) After the above facts, we are compelled to conclude, against anterior probability, that among the mammalia there exists no close relation between the BULK of the species and the QUANTITY of the vegetation in the countries which they inhabit.

If we suppose the case of the discovery of a skeleton of a Greenland whale in a fossil state, not a single cetaceous animal being known to exist, what naturalist would have ventured conjecture on the possibility of a carcass so gigantic being supported on the minute crustacea and mollusca living in the frozen seas of the extreme North ?) With regard to the number of large quadrupeds, there certainly exists no quarter of the globe which will bear comparison with Southern Africa.
