628 Notes on the Specimens of the Kankar Formation, [Dzc. 
14. Rock kankar, a calcareous sandstone, containing angular frag- 
ments of silex, felspar, and yellow clay. A few strata, about one foot thick each, 
with strata of the usual description between, form together masses of 12 feet thick 
rising to 17 feet above the surface of the water. 
Fig. 13.—Section of the clay bank above Hamirpur and below 
Secrort Ghat. The kankar (15) here appears in vertical seams in the 
scarped front of the bank, which is itself of a firm clay. 
No.16. Sandy clay, with perforations—and an imbedded wnio shell, 
open. 
Py: 17. Ramified kankar from the bank at the level of the water, Ha- 
mirpur. 
Fig. 14.—Section of part of the bank at Arroel, below Hamirpur. 
No.18. Kankar conglomerate (large rolled fragments, reunited with 
Kankar cement). 
19. Plate kankar, of botryoidal form—micaceous sand adhering : 
from Takouri near Chiladéra Ghat, it appears combined in large rocks and reefs. 
Note.—To this part of the Jamna the clay and kankar formation 
prevails. Below, fresh descriptions of rock supersede the kankar, 
except in the specimens distinguished as such. 
20. Red vitrified clay, or khangar, of variegated color, from 
Marka. The mass is about 200 feet in dimensions, rising 20 feet above the level 
of the water. 
21. Ditto, partially heated, found in detached lumps near the base 
of ditto. 
Figs. 15,16, 17.—At Agrye, Ist May, above Mhow. Veins of 
kankar (No. 22, clayey kankar), here run in veins through red clay, 
containing nodules of kankar : from the unequal wear of such materials 
by atmospheric influence, the veins are sometimes seen to protrude 
like dykes above the clay, as represented in Fig. 15, to the height of 
half a foot or more : the superficial appearance is reticulated, as shewn 
in Fig. 17. 
No, 23. Plate kankar from Kankota;—of this kind extensive beds 
and reefs occur, it is much the same as that at Pachkourz. 
The other specimens forwarded with the kankar series, are as fol- 
lows : 
No. 24. A caleedonic conglomerate of fused lithomarge, forming 
the substance of a rocky island above the Taboda hill , taken from the mass 25 to 
40 feet above the water-level. 
Specimens from Mhow, 40 miles above Allahabad. 
No. 25. Sandstone from the rock about the centre of the river, at 
six feet above the level of the water. 
26. Lithomarge, in masses, 10 feet above the water. 
27. Sandstone flag, from the Bundelkhand bank of the river. 
28. Red clay and gravel (ferruginous kankar), running in veins 30 
to 40 feet in length, 3 or 4 inches thick, taken from the same spot as No. 27.
