My dear Sir
I have found a few sponges in my collection: some dry & some in Spirits.
I do not suppose they will be of any use to you—but on the same principle that I like to look at all old rubbishy barnacles, you may like to look at & have any rubbishy Sponges.—2 I will leave them directed to you at Geolog. Soc. on Thursday next.—3
I believe I have a few more specimens but cannot now lay my hands on them.
Yours sincerely | C. Darwin
I return your Plumularia on which the beautiful & most interesting Scalpellum ornatum was attached.—4
