Summary:

CD thinks JJW’s account [in 7137] is significant for a theory of generation and should go to some scientific society; suggests additional data is needed. Quotes cases of subsequent progeny apparently affected by a previous impregnation. Perhaps not prudent to allude to "despised" Pangenesis, which CD fully believes will have its day.

Summary:

Cannot accept JJW’s invitation to a party. His health has been worse than usual for some months – can see no one nor can he go anywhere.

Is preparing a cheap edition of the Origin [6th] and will answer Mivart’s objections.

CD is pleased JJW likes C. Wright’s "Darwinism" [see 7940]. Huxley will publish a splendid review of it in Contemporary Review [Nov 1871].
