To Ernst Haeckel   3 October [1869]1

Down. | Beckenham | Kent. S.E.

Oct. 3d

My dear Häckel

I received this morning your letter of the 29th. & am heartily glad that you have had so successful an expedition.2 You give a very pleasant account of all your doings. It is, also, very satisfactory to hear from you of so many naturalists who believe in our views. I am particularly glad to hear about Sars,3 for whom I have always felt an unbounded respect.

I received some time ago your Siphonophoren, & have admired the exquisite Plates; but I have not yet had time to read any as yet, though it now stands as the top book of a pile next to be read. I am very much obliged to you for telling me of the pages, in the work & in your memoir on Sponges, for, as you know, I am a very poor German scholar, & alas shall never improve.4

Do not work yourself to death or sickness.

Let your wife5 sing that into your ears night & day.— I have forwarded your letter & papers to Mr. Norman.—6

My dear Häckel | Yours most truly | C. Darwin
