My dear Häckel
I received this morning your letter of the 29
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.
Do not work yourself to death or sickness.
Let your wife sing that into your ears night & day.— I have forwarded your letter & papers to M
My dear Häckel | Yours most truly | C. Darwin
