Along the edge of the great desert, beds of gravel, sand, and clay, some 

 like the "loess" of the Rhine, occur. The author concludes that this 

 " loess " is a subaerial deposit. F. D.

 valley, llec. Geol. Surv. Ind. vol. vii. pt. 2, pp. 51-53 ; and Quart. 

 Journ. Geol. Soc. vol. xxx. pp. 568-570. 

 On the S. slope of the Kuenlun range, above the right bank of the 

 Karakash river, are the old jade- mines — shallow holes or low galleries. 

 A gneissic or a schistose rock is traversed by veins of a white, appa- 

 rently zeolitic, mineral ; this, again, is traversed by veins of jade ; the 

 jade also occurs in nests; the colours are white, pale green, and 

 green. F. D.

North from Kashgar the first hills met were a 400-feet ridge of beds 

 of sand and clay, which the author calls *' Artush beds ;" these con- 

 tinue in the next range of hills, covered unconformably by gravel beds. 

 Further in is the Kokan range ; it has at its base green and purple 

 shales overlain by dark limestone. Five miles north of Chungterck 

 were found, in a thick bed of limestone, Triassic fossils. Near Chakmdk 

 bedded dolerite occurs, in some places columnar ; and the former position 

 of the cone of eruption was noticed. To the north rises the Terektagh 

 to 16,000 or 17,000 feet, composed of Tertiary conglomerate, dolomitic 

 limestone, slaty rocks (changing into schist), and another dark lime- 

 stone ; dip N. by W., very high. Then follows a sketch of the later 

 history of the hill-ranges before described. F. D. 



. Note on Pamir Khurd. Rec. Geol. Surv. Ind. vol. vii. pt. 3, 



p. 86. 



From Yangihissar to Sirikul and across Pamir Khurd there are no 

 rocks younger than Trias. Pamir Khurd proper is gneiss and schist ; 

 it is not an elevated x)lain, but a mere valley two or three miles 

 wide. From the hills on the south glaciers come down almost into the 

 valley. F. D.

 map. 



From the Dhjioladhar range into the Kangra vallc}'', down to an 

 average level of 2000 feet, sinuous streams of boulders are traceable ; 

 many of these boulders are rugged and angular, over 50 feet in diameter. 

 Reaching the lower open ground the streams expand. The boulders 

 are chiefly of gneiss ; in the lower portions waterworn stones are found 

 mixed up. These deposits are described in several localities ; and the 

 former presence of glaciers in several of the valleys is inferred and 

 their course laid down. The theory of glacial conditions is discussed,
