My dear L.

Gardener Ch. returned safe.—¹ Thanks for note. I am beyond measure glad that you get more & more roused on subject of species; for, as I have always said, I am well convinced that your opinion & writing will do far more to convince the world than mine.— You will make grand discussion on Man.² You are very bold in this & I honour you.—

You saw I suppose Saturday Review: argument confined to Geology, but has given me some perfectly just & severe raps on knuckles.—³ I have been like you quite surprised at want of originality in opposed arguments & in favour too. G. Jeffrey attacks me justly in letter about strictly littoral shells not being often embedded at least in Tertiary deposits.⁴ I was in muddle for I was thinking of Secondary, yet Chthamalus applied to Tertiary.— Jeffrey write me, I think nonsense, about non-migration of sea-shells.—

Possibly you might like to see enclosed note from Whewell, merely as showing that he is not horrified with us.—⁵ You can return it, whenever you have occasion to write, so as not to waste your time.

C.D. I think it likely I shall have to send long letter from H. C. Watson, not yet read by me.⁶
