1837.] Geological Specimens from Kemaon. 657 



54. Specimen of the same rock weathered and presenting the form in 

 which it is spread over the surface of the country, as well as reposing- 

 in detached blocks and masses on the summits of clay-slate mountains*. 



55. Rocks described, Inq. Kem. 106, 107, as transition limestone. It 

 forms a ridge in the centre of Shore valley as well as most of the adjoining- 

 mountain summits. It appears to be stratified but much disturbed and 

 broken. Brecciated specimens of the same. 



57. Slaty variety. 



58. Variegated brown and blue varieties of the same. The mineral 

 characters of these limestones are sufficiently distinct from those described 

 as primitive, and as this indication is confirmed by geognostic relations, I 

 still adhere to the distinctions I have drawn between them, independent 

 however of any theoretical views. 



59. Overlying variety of the same. It is not very distinct in its mine- 

 ral characters from the stratified rocks, and it may be supposed to have 

 had its continuity merely separated from adjoining masses by the same 

 set of causes as now occasion the corrosive effects on its surface. Inq, Kem. 

 107 and 108. 



60. Compact dolomite. Inq. Kem. 109. 



61. The same with chlorite and quartz preponderating. 



62. With chlorite preponderating-, the last two specimens being 

 natural as well as local links between dolomite and chlorite slate at Belket. 



63. Transition between compact dolomite and granular quartz with 

 chlorite. Inq. Kem. 114. 



64. Blue variety of the same consisting of distinct grains of quartz 

 imbedded in chlorite more or less closely in different parts of the same 

 specimen. 



65. The same, but the grains of quartz are larger, more distinct and 

 loosely aggregated as well as rounded, and altogether presenting the 

 character of sandstone. These specimens were taken from the valley of 

 Belket. 



66. Peach-blossom variety of the same, from the Ramgunga valley at 

 the bridge on the road between Petora and Almora, described, Inq. Kem. 

 115 as granular dolomite. 



67. Another variety of the same, from the same situation. The oval 

 grains of quartz appear to be in this specimen arranged so as to present 

 their longest diameters to each other, giving the mass a fibrous structure 

 and proving its chemical origin : attentive observation may detect the 

 same structure in other specimens. 



68. Another specimen from the same situation as the last. 



69. Of the same nature as 66, 67 and 68, but in a state of decay and 

 quite friable. In this form the rock is found in Goron valley 3,000 feet 

 above the situation in which the other specimens were found. 



* It is not always found reposing on clay-slate, but as is seen in many instances 

 ascendiog from beneath that rock.
