 drawn up some notes for a French translation "f my Orchis 

 book: I took out your letters to make an abstract of your 

 numerous discussions, but I found 1 had not strength or time

 French edition] alluded to your work, which will also be 

 published in English, 1 as you will see in my paper, and which 

 I will send you. 



P.S. — By an odd chance, since I wrote the beginning of 

 this letter, I have received one from Dr. Hooker, who has 

 been reading Fur Darwin : he finds that he has not know- 

 ledge enough for the first part ; but says that Chapters X. 

 and XI. "strike me as remarkably good." He is also par-

 in the note to p. l 19. Assuredly all who read your book will 

 greatly profit by it, and I rejoice that it has appeared in 

 English. 



To F. MUller. Letter 681 



Down, Dec. 1st [1869]. 



I am much obliged for your letter of October 1 8th, with 

 the curious account of Abutilon y and for the seeds. A friend 

 of mine, Mr. Farrer, has lately been studying the fertilisation 

 of Passiflora* and concluded from the curiously crooked 

 passage into the nectary that it could not be fertilised by hum- 

 ming-birds ; but that Tacsonia was thus fertilised. Therefore 

 I sent him the passage from your letter, and I enclose a copy 

 of his answer. If you are inclined to gratify him by making 

 a few observations on this subject I shall be much obliged, 

 and will send them on to him. I enclose a copy of my rough 

 notes on your Eschscholtsia, as you might like to see them. 

 Somebody has sent me from Germany two papers by you, 

 one with a most curious account of Alisnta, 3 and the other on 

 crustaceans. Your observations on the branchiae and heart 

 have interested me extremely. 



Alex. Agassiz has just paid me a visit with his wife. He
