654 Geological Specimens from Kemaon. [At 7 <*. 



No. 1, Granite (Inq. Kem. 41*) as I have stated this rock to be stra- 

 tified it becomes a matter of consequence to determine whether it be 

 granite or not. I confess I begin myself to suspect it to be gneiss 

 which has assumed the granitic form in particular spots. The whole range 

 composed of this rock (changing in places into unquestionable gneiss) dips 

 towards the Himdlaya, presenting for the most part steep declivities in 

 an opposite direction formed by the outgoing of the strata. In the lower 

 strata the mica gives place to hornblende, forming an intermediate rock 

 between gneiss and hornblende-slate as 5, 8, and 20 1. 



2. Specimen, of the granitic centres contained in the gneiss of Kalee 

 Kemaon^. 



3. Gneiss of Kalee Kemaon. 



4. Harder nodules which adhere to the surface of granitic masses. 



5. Gneiss, with quartz and felspar imbedded in mica and horn- 

 blende, from Kalee Kemaon ; it underlies the granitic rocks at Choura 

 Pany, forming the southern foot of that mountain. This specimen belongs 

 to variety a, Inq. Kem. 59. 



6. Nodules of red felspar and hornblende adhering to the granitic cen- 

 tres of gneiss at Kalee Kemaon. 



7. Mica-slate from beds of gneiss at Choura Pany. 



8. The same containing hornblende. 



9. Ferruginous slate from beds in gneiss and extending parallel with 

 the strata. Inq. Kem. 52. 



10. 11. Two interesting specimens shewing the transition between No. 5, 

 and clay-slate variat. Inq. Kem. 59. 



12. Felspar quartz with very little mica forming veins in the gneiss of 

 Choura Pany. 



13. Gneiss of Choura Pany (on the southern declivity of the mountain) 

 passing into mica-slate nearly the same as 7. 



14. Chlorit-slate with quartz from the southern part of Choura Pany. 

 Inq. Kem. 60. 



15. Ditto without quartz, 



16. Porphyritic green stone. Inq. Kem. 61. 



17. Described (Inq. Kem. 62.) as oldest gypsum from beds in mica- 

 slate 7 and 8, but I doubt its being gypsum. Von Buch found beds of 

 quartz in mica-slate just as this rock occurs : this specimen ought to be 

 more carefully examined.
