Such are the scientific results of our journey; and these met with warm approbation, not only from the Geographical Society, but from the different men of science who volunteered their services to classify them.
The academician K. T. Maximovitch kindly undertook the description of the flora, which will form the third volume of the present edition of our travels.

Inostrantseff and K. T. Kessler, professors at the St. Petersburg University; A. T. Moravitz, the entomologist; N. A. Severtsoff, W. K. Tachanoffsky, the zoologists; and A. A. Strauch, academician.
