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.

[Memorandum originally enclosed with 1760.]

On his "Insular floras" lecture.

Huxley's success as President of Section.

D. W. R. Grove's address. Grove left Darwinism to JDH after "sounding the charge".

AG is writing notice of American edition of Variation [Nation 6 (1868): 234-6].

Pangenesis is "as good an hypothesis as one can now make".

Drosera filiformis captures only small insects [but see 8989].

Writes of her experiments with butterflies.

CD's theory steadily gains ground in the U. S., despite Agassiz.

Obliged for information on Mimosa albida; if a vigorous plant behaves as JDH says, CD's notions are all knocked on the head.

Anxious to read Tyndall's answer to Tait [Nature 8 (1873): 399].

Drosera story too long for his strength. Essentially the leaves act just like stomach of an animal.

Burdon Sanderson will give some grand facts at BAAS about Dionaea.

Offers to help JDH with Nepenthes experiments. Finds experimental work always takes twice as much time as anticipated.
