184 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



of Reykjavik, where he had considerable difficulty in obtain- 

 ing good boatmen, as the Icelanders were not accustomed to 

 the labor of dredging, and were quite easily fatigued. The 

 list of mollusca obtained, principally at a depth of from 

 twenty to thirty fathoms, embraces eighty-three species ; but 

 what astonished Mr. Verkruzen was the absence of species 

 of Brachiopoda and Pecten (except islandicus), Lucina bore- 

 alis, Cardium eclule, Dentalium entalis, and others, so fre- 

 quently met with in Norway and other northern coasts. 



REPORTS OF GERMAN EXPEDITIONS. 



The report of the second German north polar expedition, 

 in 1869 and 1870, under Captain Koldeway, is in an advanced 

 stage of preparation, and will shortly be published by Brock- 

 haus, under the direction of the German North Polar Asso- 

 ciation of Bremen. This will consist, in the first place, of a 

 narrative of the voyages of the Germania and Ilansa, in- 

 cluding the thrilling account of the perils to which the latter 

 vessel and her crew were subjected, as also a memoir upon 

 Greenland and its earlier history. This portion of the work 

 will embrace numerous maps and charts, with illustrations 

 of the scenery of East Greenland and of the adventures of 

 the vessel. The second volume will be occupied entirely by 

 a systematic account of the scientific results obtained in as- 

 tronomy, botany, zoology, geology, meteorology, and hydrog- 

 raphy, the geological determinations, geodetic and magnet- 

 ic observations, all accompanied by suitable illustrations. 

 Among the collaborators of this part of the work are some 

 of the most eminent naturalists in Germany, and it will un- 

 doubtedly be of great scientific value. The whole will be 

 comprised in two stout octavo volumes, with numerous il- 

 lustrations, and it is proposed to furnish the book at the re- 

 markably low price often or twelve thalers. 



Herr Radde, the well-known traveler in Siberia, has been 

 engaged since 1864 in exploring the Caucasus and the south- 

 ern part of the Transcaucasus, and he has more recently trav- 

 ersed the eastern bank of the Caspian Sea in Leukoran, and 

 the high plateaus of Armenia and its valleys. He has made 

 some very interesting ethnological discoveries in Mongolia 

 and in the Caucasus, and has visited the so-called grave of 

 Noah, to the southeast of Nachitschewan, which is environed
