THE Expedition to Northern Siberia, fitted out by the “Verein für die Deutsche Nordpolarfahrt in Bremen”—the same Society which sent out the Second German North Polar Expedition, and published the excellent account of its results—left Bremen last week. The attention of the Council of the Society having been called to the immense unexplored area between the Jenisei and the Obi, it was resolved, as there were not sufficient funds for a naval expedition this year, to send out a small zoological and ethnographical expedition overland to the Obi, which appeared to be less known than the Jenisei. In this they received the warm support of the highest scientific authorities at St. Petersburg who were asked for advice on the subject. Dr. Otto Finsch, Director of the Zoological Museum at Bremen, was appointed leader of the expedition, and Dr. Brehm, the well-known author of “Das Thierleben” and many other natural history works was selected to accompany him. They were joined by Count Walburg-Zeil-Trauchburg of Stuttgardt, who made an expedition to Spitzbergen in 1870 at his own expense, and who is well acquainted with physics and is a good botanist. Professor Oscar Schmidt of Strasburg, who had likewise intended to go, was unavoidably prevented at the last moment. The route selected is by St. Petersburg and Moscow to Nishni, and thence in sledges viâ Kasan, Perm, Ekaterinenburg and Omsk to Semipaiatinsk. Thence a detour will be made, if possible, into the Altai. From Ekaterinenburg they will go to Barnaul and down the Obi to the embouchure of this river. They will return to Germany in the autumn—certainly not without a rich harvest of results.
