From T. H. Huxley   20 February 1871

My dear Darwin

Best thanks for your new book a copy of which I find awaiting me this morning—¹ But I wish you would not bring your books out when I am so busy with all sorts of things— You know I can’t shew my face anywhere in society without having read them—and I consider it too bad

No doubt too, it is full of suggestions just like that I have hit upon by chance at p. 212 of vol I. which connects the periodicity of vital phenomena with antecedent conditions—²

Fancy lunacy & menstruation coming out of the primary fact that one’s n^th. ancestor lived between tide-marks! I declare it’s the grandest suggestion I have heard of for an age

I have been working like a horse for the last fortnight, with the fag end of influenza hanging about me—and I am improving under the process, which shews what a good tonic work is—³

I shall try if I can’t pick out from ‘Sexual selection some practical hint for the improvement of gutter-babies & bring in a resolution thereupon at the Schoolboard⁴

Ever Yours faithfully | T H Huxley
