Dear Sir

Excuse me for not writing You immediately to thank for the large parcel of clean sheets You had the kindness to send me, I am busy translating them, the first are already in the press, so that I hope to be not very much behind the original;² the reason why I did not write immediately lay in the hope I had to have a letter from You, but either You did not send it (and in this case it is all right) or it is lost in transmission which will be a pity. M^r. Murray sent the casts directly to Russia and made a very moderate charge 14£; though I do not know what quantity of copper cast there is for the 2 volumes.—³ I wrote You in my last that my brother is gone to the Red Sea, I have letters from him weekly, Suez did not satisfy him much so he is gone a little farther to Tor, a place wher Ehrenberg has been in 1827.—⁴ I hope he will return about the 25 of February, when I’ll go to meet him at Naples and we shall try together to procure ourselves scalpellums for the verification of Your old discovery.⁵ I hope Your health got better from Your autumnal visits.⁶

Pray remember me and M^rs. Kovalevksy to M^rs. Darwin and the ladies.—⁷

Your very truly | W. Kowalevsky

P.S. Have You seen the new book of Häckel “Biologische Studien” it is very interesting, especially his discovery that the Radiolaria contain in their body 40[percent] amylum; such a fact may overtrow much of our prejudices about the dependence of animal life from vegetation an explain the economy of the deep sea inhabitants.—⁸
