148 ANNUAL RECORD OF SCIENCE AND INDUSTRY 



heuglin's explorations in the arctic seas. 



In a letter addressed by Von Henglin to Middendorff, of 

 the St. Petersburg Academy, we find the fullest details of the 

 exploration instituted by that eminent traveler during the 

 past summer in the Nova Zembla Seas. In this he remarks 

 that the original plan included a visit to the mouths of the 

 Obi and Yenisei, perhaps even extending to the island of New 

 Siberia. This, however, was found to be impracticable on ac- 

 count of unseasonable weather, as it was not till the 6th of 

 August that they reached the Straits of Matotschkin. Up to 

 that time they had met with no ice ; but after passing the 

 straits to the east there was very much drift ice. from the Sea 

 of Kara, so as almost to bar their way. Finding that the 

 northern coast of the island was entirely embargoed by ice, 

 they turned to the south, and, in passing, visited the Straits 

 of Kostin and the Nechwatowa, then Waigatsch, and finally 

 arrived at the Straits of Jugorsky on the 1st of September. 

 Here the expedition did not make any better progress than 

 in the Straits of Matotschkin, and, fearing that they might 

 be shut in by the ice for the winter, they returned to their 

 starting-place. 



Among the more important results of the voyage were nu- 

 merous soundings and measurements of deep-sea tempera- 

 tures, as also various geographical determinations, while large 

 collections of specimens of natural history were brought to- 

 gether. Among these the most interesting was the discovery 

 of two different species of lemming in Nova Zembla, and it 

 was thought possible that in Southern Nova Zembla still a 

 third species might be met with. The same animal was also 

 found in Spitsbergen. Numerous birds were obtained in 

 Nova Zembla and Waigatsch, among them the Mandt's guil- 

 lemot. Of fishes, some species of cod, cottus, and salmon 

 were obtained, and about one hundred species of plants.

ALTERATION OF THE MAP OF SPITZBERGEN. 



As the result of the explorations during the past year in 

 the neighborhood of Spitzbergen on the part of various trav- 

 elers, Dr. Petermann presents, in a new map of that country, 

 a very great change in its form, the eastern line of Northeast
