84 Address. [Feb. 



particulars about Kasligaria, besides astronomical and magnetic observa- 

 tions and topographical surveys over an itinerary of nearly 1,100 miles. 

 M. Bogdanovitch lias explored geologically the valleys of the Raskem, 

 or Yarkand, River and of its affluent the Tiznaf, and also the the 

 country in the neighbourhood of the Mustagh Ata, or Tagharma moun- 

 tains, west of Yarkand. 



Petermann^s Mittheihmgen contains a full account of Prjevalski's 

 fourth journey in Central Asia, by Dr. Carl Diener, of Vienna, with a 

 map showing the course of Prjevalski's four journeys. 



Captain Grrombtchevski, whose exploration over the Pamir to Kan- 

 jut was noticed in last year's address, left Margilan on the 13th July last 

 on another expedition to the south of the Hindu Kush. He passed 

 through Karategin and Darwaz to Kila Khumb on the upper Oxus, 

 intending to proceed to Shignanand Lake Shewa, if possible, and then to 

 Kafiristan. After following the course of the Panjah to the junction of 

 the Wanj River, he explored the valley of the latter, and then proceeded 

 by the Syr-Artchi Pass to Khin-i-ab, in Wakhan. The passage of the 

 Syr-Artchi was very difficult over more than 7 miles of ice, and at the 

 commencement of September deep snow covered the country. Being 

 refused admission into Afghanistan, he decided upon marching towards 

 the sources of the Ak-Su and the Taghdumbash Pamir, where he ar- 

 rano-ed for crossing the Ili-su-Pass to the valley of the river Raskem. 

 In October he was at Kaindyn Aouzy, on the Ili-Su, and proposed to 

 visit the sources of the Raskem river, in the Karakoram Mountains, 

 and thence explore the basin of the upper Khotan river. He claims 

 to have discovered two new passes, the Kilinj and the Kadarpur, the 

 first is, however, well known, having been visited by Col. Woodthorpe. 



Another important Russian exploring party is that under M. Grum- 

 Grjimailo, who started from Vernyi, in April last, in company with 

 his brother, to explore the Eastern Tian Shan, where he will endeavour 

 to connect Prjevalski's surveys with those of Potanin and also com- 

 plete the botanical and zoological work of Prjevalski and other tra- 

 vellers in this part of Central Asia. From the Tian Shan, he was 

 to travel by way of Turf an to Lake Lob Nor and thence explore the 

 Altyn Tag range. The latest accounts from these explorers inform us 

 that they have found that the existing maps of the Eastern Tian Shan are 

 quite incorrect. They have gathered very rich collections of vertebrates 

 and insects. It may be of interest to Indian meteorologists that the 

 spring was very late in Dzungaria, and that in the month of May, the 

 lower limit of snows on the Ala Tau range, in the latitude of 43° JN"., 

 was 7,874 feet. The winter of 1888-89 in Trans-Caspia is said to have 

 been unusually severe. M. Bogdanovitch reports heavy rain and floods, 

 in May and June last, in the mountains to the west of Yarkand.
