IS/I.] EXPRESSION. 141 



[The following letters, addressed to Dr. Ogle, deal with 

 the progress of the work on Expression.] 



Down, March 12 [1871]. 



MY DEAR DR. OGLE, I have received both your letters, 

 and they tell me all that I wanted to know in the clearest 

 possible way, as, indeed, all your letters have ever done. 

 I thank you cordially. I will give the case of the murderer * 

 in my hobby-horse essay on Expression. I fear that the 

 Eustachian tube question must have cost you a deal of 

 labour ; it is quite a complete little essay. It is pretty 

 clear that the mouth is not opened under surprise merely to 

 improve the hearing. Yet why do deaf men generally keep 

 their mouths open ? The other day a man here was mimick- 

 ing a deaf friend, leaning his head forward and sideways to 

 the speaker, with his mouth well open ; it was a lifelike 

 representation of a deaf man. Shakespeare somewhere says : 

 1 Hold your breath, listen " or " hark," I forget which. Sur- 

 prise hurries the breath, and it seems to me one can breathe, 

 at least hurriedly, much quieter through the open mouth 

 than through the nose. I saw the other day you doubted 

 this. As objection is your province at present, I think 

 breathing through the nose ought to come within it likewise, 

 so do pray consider this point, and let me hear your judg- 

 ment. Consider the nose to be a flower to be fertilised, and 

 then you will make out all about it.f I have had to allude 

 to your paper on ' Sense of Smell;' { is the paging right, 

 namely, I, 2, 3 ? If not, I protest by all the gods against the 

 plan followed by some, of having presentation copies falsely 

 paged ; and so does Rolleston, as he wrote to me the other 



day. In haste. 



Yours very sincerely, 



C. DARWIN.
