1837.] Geological Specimens from Kemaon. 659 



84. The form in which talc enters into the composition of Protogine. 



85. Rhomboidal crystals of talc. 



86. Dolomite spar from nests between the talc and limestone in Shore 

 valley. ; 



87. Variegated slate. Inq. Kem. 128. 



88. Newer argillaceous slate not variegated and found under dis- 

 tinct circumstances from the last. Inq. Kem. 130. 



89. Greyish black brecciated serpentine from the bed of the Mahikali 

 river. Inq. Kem. 131. 



90. Noble serpentine. Inq. Kem. 134. 



91. Ditto with veins of a quartzose appearance. 



92. Coarser variety. 



93. Green argillaceous slate from the vicinity of the serpentine. These 

 rocks are found near the village of Gorajht on the way to Jula ghaut from 

 Petora. 



94. Older alpine limestone copper slate. Inq. Kem. 1838. The cop- 

 per ore is contained between the slaty layers and fractures of the 

 rock. 



94|. Alpine limestone. There is another variety of this rock distin- 

 guished by its flat tabular masses forming thin beds, spread over other 

 rocks rather than accumulated in masses of great depth, such as the 

 rock represented by this specimen. I endeavoured to distinguish this 

 variety farther by the peculiar form of some of its distinct concretions 

 which resemble in shape small fishes. Inq. Kem. 140. 



95. Magnesian limestone from Shore valley : structure slaty but crys- 

 talline and compact. Inq. Kem. 142. 



96. The same, shewing the change to which it is subject by decom- 

 position. 



87. Shews that some layers are less disposed to decompose than others, 

 and that the destructive causes operate as well tranversely with regard 

 to the layers as laterally. 



98. The rock completely altered, (Inq. Kem. 43) named earthy variety. 



99. Vesicular limestone. 



100. Porphyritic septarium. Inq. Kem. 148, 



101. Vesicular limestone from the summit of several mountains. 



102. Other specimens of the same from similar situations but some- 

 what decomposed. 



103. Impressions of rhomboidal crystal in a basis undetermined, col- 

 lected from amongst the talcose rocks and protogine in Shore valley. 



104. Bituminous marlslate, valley of Belket. Inq. Kem. 154. 



105. Calcareous grit stone from the northern declivity of the moun- 

 tain that divides Belket from the plains. 



106. Argillaceous sandstone. Inq. Kem. 156. 



107. Amianthus from the junction of the talcose slate and limestone 

 rocks in Shore valley.
