From V. O. Kovalevsky   15 September 1870


15 Sept. 1870.

Dear Sir!

I have just received a letter from my brother1 in which he says that he set himself to verify Your old discovery about the supplementary males, but unhappily in whole Naples there is not a single copy of Your monography of the Cirripedia, so I make use of Your kind proposition to lend me for a short time Your own copy which I shall immediately forward to Naples, as soon as my brother has done with the book he schall send it back to You.2

At the time when he send me the letter, he was able to see only some of the Scalpellum preserved in Spirit in the museum, but has a good hope of getting a plenty supply of living ones3

Your very truly | W. Kowalevsky

31 Bloomsb. Str. | Bedf. Square.


Kovalevsky’s brother was Alexander Onufrievich Kovalevsky.
