630 Notes on the Specimens of the Kankar Formation, [Dec. 
9. Portions of human bones, (?) the two black ones being the head 
of the thigh-bone and head of the arm-bone. 
10. Two pieces supposed to have been parts of alligators. 
11. Portions of bones belonging to the skeletons of horses, buffa- 
loes, &c. 
12. The upper part of the leg-bone nearest the shoulder of a young 
elephant, or the lower part of the thigh-bone of the same animal. 
1 and 2 were taken out of a mixture of sand and kankar, partially 
exposed to the atmosphere. 
3, 4, 8,9, 10 and 11, were all procured on sloping the banks of a 
channel, the sides of which are from | to 5 feet above the lowest level 
of the river (the bank being 50 feet high.) They were dug from depths 
of from 6 to 18 inches in the firm shoal, which is composed of sub- 
stances, kankar stone, gravel, rounded bricks (vitrified clay ?) more 
or less rolled and cemented by mud and clay. 
5. Were dug out of a cleft in hard yellow clay about 9 inches deep, 
filled with black mud, about 3 feet from the surface of the water. 
6. Were found in the bed of the river about 18 inches deep, and 4 
feet from the surface of the water, during the excavation of a bund. 
12—was found on the left shore of the Jamna, at Choura, above Cal- 
pt, partially imbedded in a clay and kanker bank: all the rest were dug 
up at Karimkhan. 
Of the fossil bones those found in the shoals of kankar were the 
Jeast perfect, the petrifaction being less complete, or the fossil in in- 
ferior preservation. In the stiff clay, which composes a considerable 
portion of the bed of the river here, the fossils were in better order. 
This difference may be accounted for on various suppositions. The 
fossils, after being washed from the spots where they became such, 
might have been better preserved in the stiff clay than in the loose 
shoals ; or the change into the fossil state may have taken place in 
the immediate neighbourhood of the clay, and those found in the loose 
shoals have been carried by the water from the original place of for- 
mation, having suffered injury in their progress from their first to the 
new situation in which they are found. 
It is difficult to assign to these remains the dates of their passing in- 
to the fossil state. The greater number have been found in an exten- 
sive shoal, of partially rolled kankar, cemented by mud, and which from 
known changes in the river might be of very recent accumulation. <A 
large proportion of the fossils seem to have had a former situation in 
the hard clay of the bed of the river, however carried thence to the
