From Edward Blyth [1–8 October 1855]
Summary
Notes on Lyell’s Principles, vol. 2.
EB does not believe in connecting links between genera; there is no tendency to gradation between groups of animals.
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.
When varieties are crossed EB considers that the form of the offspring, whether intermediate or like one or other of the parents, depends upon how nearly related the parents are.
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.
Colours of Indian birds.
Vitality of seeds.
Variation among palms.
Fauna of Malaysia and New Zealand. Ranges of bird species.
