660 Geological Specimens from Kemaon. [Aug. 



108. Common quartz crystallized. 



109. Greenstone contained in the newer limestone of Shore valley. 



110. Hornblende- Belket. 



111. Porphyry from the bed of the river at Burmdeo pass. 



112. Transition between the newer argillaceous slates and granular 

 crystalline rocks called steatitic sandstone. 



113. Snow-white siliceous oolite from the Deary mountains. 



114. Granular quartz from the valley of Bara but not collected in 

 situ. 



115. The same approaching the siliceous deposits already described in 

 the catalogue, taken from the Deary mountains. 



116. Matrix forming the contents of a vein in the primitive slate at 

 Lohooghat. The vein is situated behind the rear guard. 



117. Stalagmite from Takill. 



1 18. Felspar from a vein in gneiss at Firker. 



119. Quartz from a cotemporaneous bed of clay-slate at Lohooghat 

 with a portion of the adjoining wall of the bed adhering to it. 



120. Fragments of siliceous pebble, water- worn and subsequently frac- 

 tured, found in the vein in clay-slate 116. Pebbles of this nature and 

 boulders of small size intersected in various parts as if cut, rather than 

 fractured, are common in this vein : the pieces of each pebble are found to 

 lie adjacent to each other. 



121. Transition between clay-slate and limestone., Shore valley. 



Miscellaneous. 



122. Steatitic sandstone approaching to the state of quartz, Ponar val- 

 ley. 



123. Felspar with a little quartz and mica from the veins in the gneiss 

 of Choura Pany. 



124. Veins and nests in protogine, Shore valley. 



125. From the gravel in the bed of the river Ludhoo at Belket. 



126. 127. From the same. 



128. Porphyry from the bed of the river at Burmdeo Pass. Judging from 

 the color of the precipices and the quantity of this rock found in the stream 

 as well as of III, a porphyry of the same color, 1 suspect that the great 

 central masses composing the first range of mountains next the plains, 

 consist of these rocks, and that the grit stones, both calcareous and 

 argillaceous, are only comparatively superficial. The calcareous grit stone 

 is a sedimentary deposite derived from the disturbance of calcareous rocks^ 

 probably from the mountains of limestone which are 30 miles within the 

 sub-Himalayan ranges. The argillaceous grit stone, 106, which occupies 

 a superincumbent position, from the quantity of mica and siliceous matter 

 it contains, may be in like manner derived from the sedimentary deposites 

 which took place on the upheavement of the primitive range intercept- 

 ing the space between this deposite and the calcareous mountains that 

 afforded the substratum. While these rocks themselves by subsequent
