Notes on the Caucasus.

Scarce. Walter Tschudi Lyall, a civil servant who used the pseudonym 'The Wanderer', is known for his reports on the Turko-Russian Campaign of 1877. He combines good observations on the peoples, customs, and topography of the region, with comments on the Great Game.

This work is sometimes attributed to Elim Henry d'Avigdor (1841-1895), born in Nice, who also wrote under this pseudonym.
