He forwarded CD’s queries on the insane to James Crichton-Browne who has now answered.

Enclosure 1: G. A. Graham responds to CD’s questions (transmitted by GC) on greyhound breeding and proportion of sexes reared.

Enclosure 2: J. W. Robertson’s general rule has been to preserve male deerhound puppies in preference to females.

Enclosure 3: Proportion of sexes in dog litters [for Descent, 2d ed.] from W. Forbes.

GHD’s article will not do. It is too long and the denial seems weak and confused; also, it ought to be in the form of a letter to the editor. Encloses draft of the sort of letter of denial he thinks GHD should write.

Thanks JDH for his and Huxley’s countering of the false attack on George [Darwin] by Mivart. Encloses a note to Mivart on which he asks JDH’s opinion.

Sends reference to Codrington paper on gravels ["The superficial deposits of the south of Hampshire and the Isle of Wight", Q. J. Geol. Soc. Lond. 26 (1870): 3–28]. Comments on local gravels in railway cutting and the violent agency of their removal from hills.

Errata slip forInsectivorous plants

Data on good and bad pollen-grain yields of different species. Sends sketches of two male Rhamnus catharticus flowers [see Forms of flowers, p. 294].

The Royal Society have not accepted R. L. Tait’s paper on insectivorous plants; it will be returned to CD, who submitted it.

Discusses geographic distribution of tuberculosis and possible explanations for disease-free areas and populations.

Does not think a local population with some distinct physiological character can properly be designated as a race. Thinks local conditions, not natural selection, responsible for such characters. Ernst Haeckel agrees. Asks CD’s opinion.

Does not think that publishing his letters as advertisement [for potato experiments] would help JT’s cause, so CD cannot give permission.

Babington’s surprise at JDH’s advocacy of Darwinian views at Norwich [BAAS meeting].

Criticism of the behaviour of the trustees of the British Museum [in the Challenger affair].

Thinks it would be a serious mistake for TB to give up his profession. How the Royal Society will distribute funds is as yet very uncertain, and CD feels that TB may well receive no support as his proposal is too theoretical.

Asked C. E. Bessey whether Lithospermum longiflorum was dimorphic like its relatives. Encloses CEB’s reply.

Pleased that a Grace has been submitted to confer on CD an honorary LL.D.; hopes his health will permit him to attend the ceremony.

CD asks his father to consider the offer of the Beagle voyage once more. He encloses his list of RWD’s objections and Josiah Wedgwood’s responses [see 109]. Asks his father to give him a decided answer: if "no" he will never again mention the subject.
