To John Lubbock 24 April 
I do not see a word to correct or a suggestion to make on your Paper.1 It appears to me a nice & interesting notice, & I suppose you mean to send it to theannals.—2
I am not surprised at your not having time lately to do much, I am only astonished at your ever finding time to work at Nat. History.
I shall be delighted to see you whenever you may have leisure to come.— Next week I shall probably be from home.—
Have you any surplus stock of F. W. Mollusca3 for I want some for my little vivarium with its one plant of Anacharis.4
Most truly yours | C. Darwin
I was very sorry I was not able to come for both your last very kind invitations.—
Praise for JL’s interesting paper ["On the freshwater entomostraca of South America", Trans. Entomol. Soc. Lond. n.s. 3 (1854–6): 232–46].
