Thanks him for his kind review of Insectivorous plants in the Spectator. Disputes Tait’s report of a Nepenthes that trapped a fly but did not digest it.

Wishes CD to present RLT’s paper on insectivorous plants to the Royal Society.

Will be happy to present RLT’s paper on Nepenthes to Royal Society.

Thanks CD for consenting to present his paper.

Composition of "Droserin" [see 10015].

Has CD ever come across Dischidia rafflesiana?

Has extracted a highly deliquescent substance from digestive secretion of insectivorous plants.

His paper [for Royal Society] is completed; would CD like to read it?

RLT’s paper will be sent to CD. Will CD notify him of any serious defects?

RLT’s paper on insectivorous plants is being copied.

Because CD has been unwell, he has not read RLT’s paper carefully, but it seems an important contribution to science. Hopes RLT’s chemical observations will be confirmed. It seems a great anomaly that two substances with an acid should be requisite for digestion.

RLT’s insectivorous plants paper.

The success of a recent lecture.

Abstract sent to the Royal Society. It seems to CD "uncommonly clear and well-done".

RLT to review 2d ed. of Variation and write an article on Pangenesis.

Discussion of "Survival of the Fittest".

Herbert Spencer invented the term "survival of the fittest". CD used it but found "natural selection" more convenient.

He has often spoken of natural selection’s destruction of individuals which do not come up to "proper standards of structure", which comes to nearly the same thing as RLT’s suggested distinction.

Regrowth of an amputated extra thumb.

Thanks RLT for his letter. CD took much trouble over his two cases [regrowth of amputated supernumerary digits, in Variation] but the evidence was shaky.

RLT’s two articles in Spectator [4 Mar and 25 Mar 1876] greatly honour CD.

Tait has made a good point about "Survival of the Fittest".

Dr Rudinger’s extensive inquiries show that all eminent German surgeons are unanimous about non-growth of extra digit after amputation.

J. Kollmann has written regretting CD has given up atavism and extra digits [in 2d ed. of Variation]; gives new evidence of a rudimentary sixth digit in batrachians.

Cat born tailless as a consequence of a spina bifida.

Regrowth of amputated digits is a capacity possessed by the new-born but rapidly lost.
