From N. Sobko   3 September 1872

Zagorodnoy, 58, St. Petersburg.

22 August/3 September 1872.1

Sir,

Having recently learned that You have brought to a conclusion Your new work: Expressions of Animals, and being convinced that the russian public will impatiently expect the appearance of this book in russian language as it always used to expect the appearance of all Your productions, I take upon myself the liberty of disturbing You with my request: have the kindness of communicating to me whether I am to hope to receive from You by degrees the proof-sheets, so that I might translate into the russian language Your new work after those proof-sheets and publish my translation at the same time with the English original.2

I have, Sir, the honour to be respectfully | Your most obedient servant | N. Sobko.

Expression was published in November 1872. The Russian translation of Expression was made by Vladimir Onufrievich Kovalevsky ([Kovalevsky] trans. 1872). No further correspondence with Sobko has been found.
CD forwarded this letter to Vladimir Onufrievich Kovalevsky (see letter from V. O. Kovalevsky, 10 September 1872), who thought that the author was a woman.
