80 Address. [Feb. 



M. Dutreuil de Rhiiis, the author of an exhaustive monograph on 

 Central Asia, has, at the instance of the French Academy, undertaken 

 a scientific exploration in Chinese Turkistan accompanied by M. Gre- 

 nard, a student of the School of Living Oriental Languages. At the 

 last news he was at Khotan and would winter there. He had made 

 meteorological and astronomical observations on his way, and had ac- 

 curately determined the position of Khotan astronomically, as 37° 6' 35" 

 N. lat., 79° 53' 15" E. long, from Greenwich, and 4639191 feet above 

 sea-level. He had also been exploring the country about Keria and 

 Polu. 



Mens. J. Martin, whose journey was noticed in the Address for 1890, 

 appears to have met with many misfortunes. An attempt to proceed 

 from Sutscheu from east to west along the northern slopes of the Altyn 

 Dao-h to Lob Nor, which might have settled the question of the exis- 

 tence of the lake, failed owing to his being unable to obtain guides. He 

 was obliged to make a detour across the Gobi, and proceeding via 

 Hami, Karashar, and along the Tarim to Lob Nor, and then along the 

 Cher Chen river, he arrived at Cher Chen on the 20th June and returned 

 to Russia. 



Accounts of their adventurous journey through Asia have appeared 

 from the pens of Prince Henry of Orleans and Mons. Bonvalot. The 

 Bulletin de la Societe de Geographie contains a short account by the 

 Prince, illustrated by an excellent map. A complete history of the 

 journey by Mons. Bonvalot has been published under the title of " Paris 

 a Tibet," and also an English translation of it. 



In the Zeitschrift der Gesell. far Erdkunde zu Berlin, Dr. G. Wegener 

 has very fully discussed the orography of the Kuen Lun range, which 

 has a length of about 2,390 miles with a maximum breadth of about 500, 

 and may be roughly estimated to cover 425,000 square miles. He 

 also discusses the geology of the Kuen Lun and surrounding regions, 

 and the observations of Richthofen, Loczy and other travellers. The 

 paper is illustrated by a map containing much that is new, and accom- 

 panied by a tracing showing the routes of travellers in Central Asia. 



The Proceedings B. G. S. for July, contain a very interesting paper 

 entitled, " Our present knowledge of the Himalayas," by Colonel H. C. 

 B. Tanner, late of the Survey of India, an officer who probably knows the 

 different parts of the Himalaya mountains better than any other. 



Under the auspices of the Royal Geographical Society an expedi- 

 tion has been arranged for to explore the high peaks and glaciers of the 

 Knra-Koram. It will be under Mr. W. M. Conway and the Hon. C. G. 

 Bruce (5th Gurklms), who will be accompanied by Mr. Eekcnstein, a 

 practised Alpine climber, Mr. McCormick, an artist, and a Swiss guide.
