1833.] and on the Fossil Bones collected on the Jamna. 627 
Sketch 5. Plan of the locality. 
a. Present bank of the river, 40 to 60 feet above the lowest level of the dry 
season, 
4. former bank, 100 to 140 feet above ditto. 
ce. Bank, in, or near which the slabs are found. 
2.—Notes on Specimens of Kankar and Rock taken from the Bed of the 
Jamna, between Agra and Allahabad. (Plate XXIV.) 
Fig. 6—represents a section of the river bank at Sinjaity, above 
Etdwa, with the kankar jutting under water. 
No. 1. Loose kankar gravel, cemented with clay and lime. 
2. Ditto, with kankar cement: micaceous sand. 
3. Botryoidal kankar. 
4. Resembles 2, but more solid. 
Fig. 7.—Kaldysar, at the junction of the Sinde, 20th April: 
No. 5. Hard sandy kankar. 
6. Stalactitic kankar, rich in lime. 
Fig. 8—isa plan of the surface of stratum A in the last sketch, 
which much resembles the filling up of the natural cracks, formed on 
the drying of a clayey soil, with a carbonaceous and sandy infiltration. 
Fig. 9—shews the general elevation of the specimens from Ka- 
laysar. The main bank immediately above rises to the height of about 
70 feet, and at a furlong further back, to a total height of 130 feet ; 
above the kankar the bank is of fine clay. 
No. 7. A concretion of rolled fragments of kankar. . 
Fig. 10—is a section taken at Kanjosa, at the junction of the 
Sinde. Were the nodular kankar lies in inclined strata in a hard clay, 
upon the horizontal surface of which rests a flat plate of kankar, (simi- 
lar to that extracted from the bed of the Jamna ?) 
Fig. 11.—Himatpir, 20th April. A mass of nodules in close 
contact, but disposed in strata nearly horizontal; some at 12 feet above 
the level of the water, some at less. The kankar which has acted as 
a cement to the mass is seen in veins, 
No. 8. Hard ramified kankar. 
9. Smaller, of various forms. 
At Burlét, below the junction of the Chambal, 20th April. 
No.10. White kankar in sandy clay ; of this there are extensive shoals, 
which offered obstructions to the navigation. 
No.11. Rock kankar, a granular concrete, with marks of shells ? Stra- 
tum, two feet thick, sixty feet above the lowest level of the river: total height of 
the precipitous bank about 100 feet. 
Fig. 12.—At Nant, between Calpi and Hamirpir, the measure- 
ment and nature of the strata are shewn in the sketch. 
No.12. Is a firm clay, 
13. A sandy marl, effervesces with acids.
