My dear Frank

Many thanks for all your very useful criticisms, all of which adopted except one & has been partly adopted.— It is a good job for you, but an accursed one for me that the Printers have quite ceased sending me slips.² I shall get my Worm little book done first, if they do not look sharp.—³

Hooker was very much interested about the pulvinus of Desmodium & about the young plants not bearing lateral leaflets. & about their movement at a lower temp. on seedlings.⁴ By the way the big envelopes which you use are made of such atrociously bad paper, that everyone has arrived more or less burst— one came in fragments, patched up with sealing wax by Post office at Stafford I think.⁵ Anyone c^d pick out anything from within & you had better not use them.—

I send paper by Stahl; he has sent me a copy; if you write pray thank him for me & you may say, if you like, that I fully appreciate the interest of his observations.⁶

Good Bye— I am tired with writing.—

My kindest remembrances to all your party— you were quite right to send Bernard⁷ home in my opinion.— | Yours affect. | C. Darwin
