nasium or public school of Smolensk, finishing his studies at the Academy of the Staff Corps. From early life he displayed a strong love for natural science, and it was to gratify these tastes that he applied for and obtained permission to serve in Eastern Siberia. Thither he proceeded in 1867, and there he remained two years, occupying all the time he could spare from his official duties in hunting, shooting, and collecting objects of natural history. On his return to St. Petersburg in 1869 he published his 'Notes on the Ussuri,' containing a great deal of information on the eastern boundaries of Russia in Asia. Soon after its appearance in 1870 Lieut.-Col. Prejevalsky prepared for his second greater expedition, for which his previous travels and studies had served as a preparation. His companion and helpmate throughout this arduous undertaking was Lieut. Pyltseff. I have only to add that, from a letter recently received from him, I learn that he is preparing for a third expedition, and that he hopes this time to penetrate to Lob-nor, and possibly from that quarter into Tibet.
London: January 1, 1876.
