The altitude of the most northerly point to which the Doctor traced the wonderful river was a little in excess of 2,000 feet; so that, though Baker makes out his lake to be 2,700 feet above the sea, yet the Bahr Ghazal, through which Petherick's branch of the White Nile issues into the Nile, is but 2,000 feet; in which case there is a possibility that the Lualaba may be none other than Petherick's branch.

Now, for the sake of argument, suppose we give this nameless lake a length of 6 degrees of latitude, as it may be the one discovered by Piaggia, the Italian traveller, from which Petherick's branch of the White Nile issues out through reedy marshes, into the Bahr Ghazal, thence into the White Nile, south of Gondokoro.
