Dear Miller

After an interval of two or three years I am finally preparing for press some of my geological notes—¹ I find in them some blanks, where I intended to introduce the name or some remarks on a few of the more interesting specimens, which you were so kind as to undertake to examine.— I have looked over a heap returned from you with their names &c &c, but it appears to me, that there must be some still, in your possession & these are the ones which now cause hiatus’s in my fair M.S. Will you add to your former kindness by finding out for me soon, whether you still have not some specimens & further by endeavouring to give me some information, on them.

In my note book I find opposite 378 (yellow,)² “a prism of 79$\frac{1}{2}$, not yet ascertained”—so this I presume you have it & it is one from the unique manner, in which the cells are half filled up horizontally, I am curious to know something about. No. 240 & 246 (white), I find were deposited with you, & I can now discover no trace of them,— they are what Sedgwick would, I am sure call “beastly rocks”— & they entirely defy me to give them any kind of name.— yet they form an entire island, though to be sure a small one³

I shall be very much obliged if you can let me have answer soon. — My long ill-health has put all my schemes out but I hope now slowly to make up arrears. I have left London & bought this place & I find the change very agreeable.—

All men, who feel interested in the welfare of the Geological Society, ought if they possibly can to attend the Special general meeting on December 3^d—. Pray mention it to all friends of the Soc: If the meeting be not well attended, it is very possible, it may be last meeting ever worth attending, at least some think so. I hope better things⁴

Ever Yours, C. Darwin
