A day or two ago I saw on a farm near this a beautiful specimen of striping on a horse. The animal is a dark dun cob, with a very divided shoulder stripe coming off from the spinal one on either side. Each shoulder stripe then divides into three prongs, and each prong ends in a sharp point. All the legs are black as far as the knees (_carpi_ and _tarsi_), and above the black part for a considerable distance all four legs are deeply marked with numerous stripes. I can get no history of parentage. If you would like a drawing I can send one, but perhaps you have already as many cases as you want in the 'Variation.' Very sincerely and most respectfully yours, GEO. J. ROMANES. _To Professor E. Schäfer._ Dunskaith: Sept. 1875. My dear Schäfer,--I have to apologise for having left your last letter so long unanswered, but there has really been nothing going on here to make it worth while writing. I gave my careful consideration to all you said about publishing, and at one time nearly decided to wait another year. But eventually I sent in the paper.[9] It seems to me that the histology can very well wait for future treatment--that its absence is not sufficient justification for withholding the results I have already observed. These results, after all, are the most important; for they prove that some structural modification there _must_ be; whether or not this modification is _visible_ is of subordinate interest. Besides, I do not, of course, intend to abandon the microscopical part of the subject altogether. In my view, inquiry into function in this case must certainly always precede inquiry into structure; for although, when all the work shall have been collected into one monograph, the histology must occupy the first place in order of presentation, very little way could have been made by following this order of investigation. I also had to reflect, that if I postponed publication, it would be impossible to expect the R.S. to publish the results _in extenso_,--_i.e._, I should have to bring out the work through some other medium. And in addition to all this, there came a letter from Foster preaching high morality about it being the duty of all scientific workers to give their results to others as soon as possible. As I said before, I thank you very much for the consideration and advice you have given, but I know that you would not like me to feel that the expression of your opinion in a matter with which you are not so fully acquainted as myself should lay me under any obligation to be led by it, after mature consideration seemed to show that the best course for me to follow was the one which I took. Hoping soon to see you, I remain, very sincerely yours, GEO. J. ROMANES. P.S.--I forgot to say that I acted upon your suggestion about the Linnean, and have been proposed by Darwin, Hooker, and Huxley. _From C. Darwin to G. J. Romanes._
