1. On the Geology of a Portion of the Himalaya Mountains 

 near Subathoo. By Major Vicary. 



[Communicated by Sir R. I. Murchison, F.G.S.] 



The section which accompanies this paper is an approximation 

 drawn up partly from memory, and in part from my notes. The 

 line is taken in a general way in a direction from S.W. to N.E., and 

 does not pretend to be very exact. Ha\ing thus premised, I shall 

 attempt to describe the rock formations, starting from the most 

 recent, viz. the Siwalic Range of hills. 



No. 1 of the Section marks the old beach of the Tertiary sea 

 which formerly covered North-Western India, and is composed of a 

 thick bed of rounded water-worn boulders, which gradually thin off 

 towards the plains. No. 2 is the Siwalic Range of sandstone hills 

 (Miocene ?) so ably described and illustrated by Falconer and Cautley 

 in their ' Fauna Antiqua Sivalensis.' I may here add, that the same 

 sandstone is prolonged in a north-westerly direction vid Kote-Kangra 

 to and beyond Jumboo, and in that direction occupies a much greater 

 superficial area, extending even to the old Fort of Rotas on the road 

 from Jelum to Attock. 



The Pinjore Valley (No. 3), like that of Deyrah Dhoon, is filled 

 to a great depth with rounded water-worn boulders, beneath which 

 the Siwalic beds are masked. At Buddee, sandstone (No. 4), not 

 unlike that of the Siwalics, appears at the surface, but I have never 

 found fossils in it, and all connection with the Siwalic beds is con- 

 cealed beneath the boulders of the Pinjore Valley. Hence rise the 

 lower and outer hills of the Himalayas. At No. 5 of the Section we 

 meet confused strata of variegated shales, the prevailing colour being 

 red and yellow : I was unable to detect fossils of any kind in them. 



The Kussowlee Range, No. 6. — I have traces of TMrrifella in some 

 calcareous sandstone beds near the crest of the range, and the rocks 

 in many places appear to have been subjected to the action of heat, 

 though I was unable to detect any igneous rock. 



No. 7. — Descending from this range into the valley of the Chota 

 Gumber river, and about four miles short of it, a section formed by a 

 watercourse, running at right angles to the range, is exposed, exhibiting
