Does not believe shortage of food can directly produce any heritable effect on size.
Comments on significance of variations discussed by Lyell. Variation in dentition and coloration.
Behaviour of elephants and monkeys.

Thinks that in the struggle for existence hybrids, and varieties generally, must be expected to give way to the "beautiful & minute adaptation" of the pure types.
