John-Tallis-1851-Tibet-Mongolia-and-Manchuria-33621, Henry Winkles

Map of the northern and western part of the chinese empire - "thibet, mongolia, and mandchouria". The borders are shown as per the 1686 treaty of nerchinsk. (they were to be changed drastically in 1858-60, by treaty of aigun and subsequent agreements). The main russian center in transbaikalia is still nerchinsk, rather than chita. The outline of sakhalin island is already shown fairly correctly, but the body of water separating it from the mainland is still labeled "gulf of tartary" (rather than '"strait). Date: 1851.
