For a detailed account of the Russian botanical collections 
and collectors, we may refer to a historical sketch of the 
progress of botany in Russia, ete., by Mr. Bongard, the super- -

burg, published in the “ Recueil des Actes” of this institution 
for 1834. An English translation of this memoir is published 
in the first volume of Hooker’s ‘“ Companion to the Botanical 
Magazine.”
