130 GEOLOGY. 



tho Punjab and Turkistan, there are scattered, according to their loca- 

 lity, notes on the following geological subjects : — Connexion of the 

 form of the ground with its structure : Marks of old glaciers on ranges 

 where none now exist, as on the Panjal mountains : Pormer extension 

 of the present glaciers, including proof of the existence of one in Nubra 

 (Ladakh), which had a thickness of 4000 feet : Avalanches in recent 

 times, accounting for some stone-heaps observed: Glacier-lakes and 

 floods caused by them : Great lake and flood on the Indus caused by a 

 landslip : The origin of the Deosai plateau, at a height of 12,000 feet, 

 lliver and lake deposits in Baltistan 3000 feet above the present river : 

 The former extension of the salt-lakes of Ladakh, and their origin by 

 damming by alluvial fans : Salt and Soda deposits : Lacustrine beds 

 on the Lingzhithang plateau, 17,000 feet above the sea — the lake that 

 produced them having been formed by alluvial fans and old glaciers as 

 dams. P. D,

A condensed sketch of the Geology of India, from the works of 

 the Indian Geological Survey, and of various writers. Separating 

 India into two Geological Provinces, (1) the Peninsula, (2) the Alluvial 

 Plain, the Himalayas, the Salt Eange, and the hills W. of the Indus, 

 the writer describes each formation as exhibited in these two Provinces; 

 correlating aU, as far as possible, with the European rocks. P. D.

 during the Talchir period. Rec. Geol. JSurv. Ind. vol. viii. pp. 16-18. 



A detailed note of the occurrence, before observed, of ice-markings 

 in the Talchir boulder-clay, which is presumably Palaeozoic. At Irai, 

 10 miles W.S.W. of Chanda, in lat. 19° 53', 900 feet above the sea, the 

 boulder-bed contains masses of limestone, quartzite, and granite, the 

 larger ones about 2 feet across ; some are worn smooth, some are stri- 

 ated in fine parallel lines. This rests on a surface of limestone-rock, 

 which (as exposed for a length of 330 yards) is polished, scratched, and 

 grooved ; the stria? are in long parallel lines running N.E. and N.N.E. 

 The author concludes that the evidence for the glacial origin of these 

 deposits is as conclusive as that for the ice-age formations of Europe.

Gives an account of Dr. Stoliczka's specimens, collected in the expe- 

 dition to Yarkand.^ The most interesting are certain rounded objects 

 resembling Romer's Astylospongia, from the Korakoram chain, a large 

 brachiopod, probably Pentamerus Knujhtii, from the Koktan range, 

 many other Silurian fossils, a number of Carboniferous Limestone 

 species, some beautiful Triassic fossils, and a few Jurassic forms. 

 Kcfcrs to the author's studies of the flora of the Jurassic rocks of Cutch, 

 which is like that of tho Yorkshire Oolites. Regards the Eajmahal
