Many of these circulars were posted with great care to recent addresses, but the response was quite disappointing. No useful prints were obtained, and most recipients took no notice whatever of the request. I have since thought the question may have been confused with palmistry. It was not easy to get impressions from the paws of monkeys, apes, and lemuroids in Japan. Some few that were obtained at once betrayed a very strong similarity to those of man, and it seemed that a wider study would yield some hints, perchance, as to the path of man’s ascent. On the 15th February of the same year (1880), I wrote to the great pioneer in this field, Charles Darwin, sending specimens of prints and some outline of my first tentative results, and requesting him to aid me in obtaining access to imprints from lemurs, lemuroids, monkeys and anthropoid apes, as I had found them to show lineation patterns which I hoped might be serviceable to elucidate in some degree the lineage of man. I had failed to find any trace of references to these phenomena in any anatomical or biological work within reach. The few Oriental works I had seen were full of absurd phantasies and were allied to palmistry, but contained Buddhist and Taouist figures nowhere to be found in nature. The great naturalist’s reply, in his own handwriting, sent to me two years before his death, was as follows:-- “_Via_ Brindisi. _April 7th_, 1880. Down, Beckenham, Kent, Railway Station, Orpington, S.E.R. “Dear Sir, “The subject to which you refer in your letter of February 15th seems to me a curious one, which may turn out interesting; but I am sorry to say that I am most unfortunately situated for offering you any assistance. I live in the country, and from weak health seldom see anyone. I will, however, forward your letter to Mr. F. Galton, who is the most likely man that I can think of to take up the subject to make further enquiries. “Wishing you success, “I remain, dear Sir, “Yours faithfully, “(_Signed_) CHARLES DARWIN.” This letter, with the envelope addressed by Mr. Darwin himself, and showing its postmarks, is in the library of the Royal Faculty of Physicians and Surgeons. Mr. F. Galton, afterwards Sir Francis Galton, a cousin of Charles Darwin, wrote in _Finger-Prints_, which was published by him in 1892, that his “attention was first drawn to the ridges in 1888 when preparing a lecture on Personal Identification for the Royal Institution, which had for its principal object an account of the anthropometric method of Bertillon, then newly introduced into the prison administration of France.” [p. 2.] In _Nature_, October 28th, 1880, appeared my article which was indexed shortly afterwards as the first contribution on the subject, in the _Index Medicus_ of the United States, thus: “Faulds, H.--On the skin-furrows of the hand, _Nature_, London, xxii, 605.”
