original design was to survey in three years Trans Baikal, and 
the district between the upper Lena and the Wittim. But the 
investigations having extended on one side to the Amoor and 
aving been impeded on the other, the party was to continue in 
the field during 1858. Notices of the progress ‘of the expedi-

of Maximowi itsch, who has been travelling for the Imperial 
Botanical Garden of St. Petersburgh. His letters have been 
published in the bulletin of that establishment, and many of the 
plants which he collected described by Rupre echt. Maximowitsch 
travelled part of the time with Schrenk, and part of the time 
independently. 
rom this brief indication of the explorations which have 
lately been made under the patronage or direction of the Russian
