Anton P. Chekhov left after him a broad epistolary heritage counting over ten thousand letters. This heritage has not been yet fully published, and by all we know may forever remain so, mainly due to the letters' not having survived these years. Among the published letters of Chehkov, however, there still remain some abstracts, which never have been printed, mainly due to their ”obsceneness”. This article attempts to prove that those unprinted abstracts, however ”obscene” they are, contain some pieces of information most precious for our understanding of Chekhov's conduct and his attitude towards certain aspects of life reflected in his realistic novels.
