Recently I saw, from one of the Scrivener articles, that Tischendorf did mention, in one of his publications, probably 1862, the Uspensky account. (Later he had a doctrinal back-and-forth with Uspensky.) Tischendorf wrote about it as a minor element, that was not very relevant.

Yet the Uspensky account actually shows that Tischendorf blatantly lied about the 1844 visit. So it would be interesting to dig this up a little further and get the exact Tischendorf quotes about the Uspensky report.
