My dear Darwin
I was very much gratified to hear by your letter of a month back that you were a little better, & I have since heard occasionally through Huxley & Lubbock that you are not worse.1 I sincerely hope the summer weather & repose may do you real good.
The Borneo Cave exploration is to go on at present without a subscription.2 The New British Consul3 who is going out to Sarawak this month will undertake to explore some of the caves nearest the town, & if any thing of interest is obtained a good large sum can no doubt be raised for a thorough exploration of the whole country.— Sir J. Brooke will give every assistance & will supply men for the preliminary work.4
I send you now my little contribution to the theory of the origin of man—5 I hope you will be able to agree with me— If you are able I shall be glad to have your criticisms. I was led to the subject by the necessity of explaining the vast mental & cranial differences between man & the apes combined with such small structural differences in other parts of the body,—& also by an endeavour to account for the diversity of human races combined with man’s almost perfect stability of form during all historical epochs—6 It has given me a settled opinion on these subjects, if nobody can shew a fallacy in the argument.
The Anthropologicals did not seem to appreciate it much, but we had a long discussion which appears almost verbatim in the “Anthropolog. Review”.7
As the Linnæan Transactions will not be out till the end of the year I sent a pretty full abstract of the more interesting parts of my Papilionidæ paper to the “Reader”8 which as you say is a splendid paper—9
Trusting Mrs. Darwin & all your family are well & that you are improving Believe me | Yours most sincerely | Alfred R. Wallace
C. Darwin Esq.
On the Borneo cave exploration.
ARW will send his contribution to theory of origin of man. The vast mental and cranial differences between man and apes, whereas structural differences in other parts of body are small. The problem of explaining diversity of human races along with the stability of man’s form during all historical epochs. Discussion with "Anthropologicals" [following reading of ARW’s paper, "The origin of human races", before the Anthropological Society, 1 Mar 1864].
