I will begin this very evening dotting down a few remarks on Lyell; though, no doubt, most will be superfluous, and several would require deliberate consideration.

Anyhow, such notes may be a preliminary aid to you; I will send them in a few days' time, and will do anything else you may wish...
P.S .-- I have had a letter from Henslow this morning.

He comes here on [Thursday] 25th, and I shall be delighted to see him; but it stops my coming to the Club, as I had arranged to do, and now I suppose I shall not be in London till December 16th, if odds and ends do not compel me to come sooner.

Of course I have not said a word to Henslow of my change of plans.

I had looked forward with pleasure to a chat with you and others.
P.S.
