My dear Henrietta
I shall send off today or on Monday, registered, the M.S. on the use of the Voice for Expression.2 It is an extremely poor affair, but I must say something, & have nothing worth saying. I have no copy of the M.S. so please lock it up carefully, for I hate it to that extent that it wd. break my heart to write it again.— Keep it till we come to London, & very nice it will be then to see you.—3 No doubt style wants improving, but I am sick of altering it.— Pray ask Litchfield whether I have succeeded in giving what he means. I do not know whether he ever was thanked for his M.S. which I was very glad to read several times over,4 & shall keep for the Descent, in case I shd wish to correct the part about music.5 For the present work music comes in only quite subordinately. I agree with Litchfield, & had come to the conclusion before that Spencer does not really explain cause of change in pitch, intervals &c &c neither in emotional speech nor in music.6 But it seems to me very good to point out, as Spencer has done, that they are connected.— George has indoctrinated me a little & shown me passages in Helmholtz.7
If you find any sentences “the most horrid which you ever read in your life”—pray correct them; but do not bother yourself about corrections.8
Poor dear soul I have been very sorry that you have kept so poorly, & you seem to me wonderfully patient.9
Your affectionate Father | C. Darwin
