troyed by fracture. On the Pass of Chowr Bunaik, the talcose rock is 

 fairly established, being occasionally schistose, occasionally amorphous 

 or massive. It is of a white colour and beautiful nacreous lustre. 

 Descending thence, various mixtures of this mineral, (prismatic talc 

 mica,) with quartz, are found sometimes inclining to a green colour, 

 and apparently allied to chloritic schist, sometimes to a blue, and passing 

 into argillaceous schist. Alternating beds of the green schist and 

 quartz rock were observed, very regular and well-defined. 



155. In the neighbourhood of the village of Kurrimee, the rock is a 

 mixture of white granular dolomite and talc. The latter is sometimes 

 found in beautiful nacreous scales, disposed in nests or nodules, at other 

 times intimately mixed with the particles of the dolomite. In the latter 

 case, the rock is extremely friable, and resembles very strongly the 

 dolomite of the Alps. This rock is succeeded by a schist of an ar- 

 gillaceous character, very soft and tender, and of a dark blackish grey 

 colour. The schist is occasionally green in the ascent to Tobne Binag, 

 where the view of the mountains discloses several beds of talcose 

 schist of a whitish colour ; descending to the village Bugur in the 

 bottom of the glen, limestone is the rock. It is often very impure, 

 being highly charged with argillaceous or siliceous matter. It is 

 regularly stratified, dipping N. 48° E. at an angle of 60 \ The strata 

 are sometimes curved. 



156. This limestone continues in the ascent to the high Pass of 

 Cheeoonga Binag, the whole of which ridge is composed of it. With 

 occasional patches of schist of an argillaceous character, it still 

 accompanies us by the village of Ingthana to Bynsaree, in the route 

 down the glen in which those villages are situated. The strata are 

 sometimes fissured and cracked in every direction, and in some cases so 

 fragmentary, that large masses have fallen out, thus giving rise to exten- 

 sive caves. From Bynsaree, the route passes up a lateral glen to 

 Soomchala, crossing an elevated ridge. On this ridge and the immediate 

 ascent to it, argillaceous schist is found of a reddish brown colour, 

 earthy composition, and splitting readily into rhombohedral fragments. 

 This rock is sufficiently exposed also in the descent to Soomchala, 

 where it is remarkable for its many changes of colour, within a small 

 space ; as also for the rhombohedral cleavages passing into the straight 

 schistose.
