Dear Sir
I thank you for your extremely kind letter.—2 I have long been much interested on Expression in man & animals, & I have sent enclosed queries to various parts of the world.3 I have received only a few answers, chiefly from Australia, & none in regard to true Negroes.—4 You may, therefore, believe, how truly obliged I shd feel for answers even on one or two points alone.— But you will find observation (at least all others have found it so) difficult in the extreme. Sympathy makes even hardened surgeons forget the subject at the moment.— You will find it necessary often to refresh your mind by reading the queries & to recall the subject to your recollection. If you will attempt to do so you will confer a very great kindness on me. I have had no answers about (5),—an expression well known to the old Grecian statuaries.—5
By a very odd chance, yesterday I was wishing I knew any observer on the Guinea coast! It is said there is there a breed of sheep in which the rams alone are horned; & another breed in which the rams alone have great beard or ruff of hair on the throat. Now I much want to know whether the horns appear later or earlier in life in these ram-lambs, than in breeds in which both sexes are horned. If any horned breed exists in same country a comparison of the rams of the same age of such breed, with the rams of the breed in which the females are hornless, would be fairest. But actual age at which horns appear wd be very useful to me. Also at what age the throat becomes hairy in the second breed, if indeed such a breed exists.—
Of course you will attend to the Gorilla & Chimpanzee; in regard to former I have seen directly opposite statements on the fact, whether the upper or lower surface of body is the most hairy.— I presume that it is true that the voice of the male is the most powerful.
I sincerely wish you health & success in your researches & I remain Dear Sir with my thanks for your kind offer | Yours very faithfully | Ch. Darwin
P.S. | I may add one other subject, on which I have long been collecting information, viz what style of beauty is admired by the wild natives of each land. Whether negroes, for instance, admire a jetty black skin & woolly hair, & their own characteristic features.—
Also how far in a quiet sort of way women of barbarous tribes have any influence in leading particular men to woo them or purchase them from their parents.—6
If you have time when in Africa to write to me on such subjects, I shd. be greatly pleased.—
C. D.
