My dear Sir

I shall send my M.S to Printers in about a month’s time, so I must settle about title.— My family shake their heads in the same dismal manner as you & M^r. Murray did, when I told them my proposed title of “The Circumnutating Movements of Plants.”²

Now will you kindly consider the following point. My book with title of “The Movements & Habits of Climbing Plants” is generally known, as merely “Climbing Plants” & is so lettered outside. Would it not be permissible under these circumstances to entitle the new book simply as

“The Movements of Plants”.—

This would be a quite correct title.—

Or I might put

“The Nature of the Movements of Plants”

but I do not like this so well.

One of my sons suggested

“A contribution to the Physiology of Plants:

Movements of Plants.”³

Do kindly give me your aid & believe me | Yours very sincerely | Ch. Darwin
