Dear Sir

I am very much obliged to you for your kindness in having sent me your photograph which I am happy to possess. I would have thanked you much sooner and answered your benevolent letter if I had not had in view to send you in the same time a little memoir on some observations (mentioned to you in my letters) But just now I hear this memoir will be published only in the next months.

Also I am obliged to you for reminding me of Delpino's work on fertilization. As now I am a regular reader of the Bot. Zeitung, I have read Hildebrand's review of it. Although of this matter, as far as our Westfalian plants are concerned, only few remains to extricate, I will continue to pursue it, in order to understand by which causes the various and frequently very complicated contrivances of flowers have been effected. For this purpose I will never be disgusted even of repeating chiefly the observations made by others.

<  >ly I have undertaken a new subject <of in>vestigation which I intend to <p>ursue during several years. I have begun to transplant turfs of mosses on other places in order to state which differences in structure are effected by altered conditions of life. As sometimes I have found the last shoots of moss turfs representing a variety widely different from the older shoots of the same turfs I believe mosses more than higher organized plants apt to show the effects of altered conditions of life.

If you wish some observations to be made by me during the next summer, I will be happy to can accomplish any of your wishes.

With the greatest respect I remain | dear Sir, yours very faithfully | H. Müller.

Both papers discussed, or alluded to, CD's claims regarding the necessity of occasional crossing between hermaphrodite plants of the same species (see Origin, p. 96, and Orchids, p. 359). CD's annotated copy of Delpino 1867a, with three pages of additional notes, is in the Darwin Pamphlet Collection--CUL. His copy of Delpino 1867b is also in the Darwin Pamphlet Collection--CUL.
