My dear Lubbock

Very many thanks for your Book: I have read 4 or 5 Chapt^s. with extreme interest, too much interest for the good of my internal viscera. It makes me groan that you had not published 4 or 5 months ago: I sh^d have so profited & saved so much work.— But on some very important points for me, I shall be able & must modify what I have written.—² I see that we have struck on some quotations & points in common; but it has surprised me, as on the ornamentation of savages, how largely we have collected our facts from different sources.—³

I see we differ a good deal about “moral sense” or rather approach the subject from different points of view; but hardly two men ever do agree on this perplexing subject.— I expect that your book will be a great success.—⁴

I have not yet even looked at the Thysanura, which I shall always love after your description of their playing like lambs & the sweet coyness of the females.—⁵

Your note of the 16^th about the Census did not reach me till 10 oclock on the 18^th when it was too late to answer. Moreover, I understood from D^r Farr, that the detailed manner of putting the query w^d be left to his Office⁶
