to the Gardeners Chronicle, where it appeared. 1 have lately Letter 680 

 drawn up some notes for a French translation of my Orchis 

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

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

 to do so, and this caused me great regret. I have [in the 

 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 Filr Darwin : he finds that he has not know- 

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

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

 ticularly struck with one of your highly suggestive remarks 

 in the note to p. 119. Assuredly all who read your book will 

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

 English. 



To F. M tiller. Letter 68 1 



Down, Dec. 1st [1869]. 



I am much obliged for your letter of October iSth, with 

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

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

 of Passifiora? 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 Eschscholtzia^ as you might like to see them. 

 Somebody has sent me from Germany two papers by you, 

 one with a most curious account of Alismaf 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
