V.—Notes on the Specimens of the Kankar Formation,and on Fossil Bones 
collected on the Jamna. By Captain E. Smith, Bengal Engineers. 
[Read 26th December.] 
Captain E. Smiru has been engaged for some years in removing the 
obstructions to navigation in the river Jamna, between Allahabad and 
Agra. These obstructions, as is well known, consist of sandstone rocks 
and kankar banks, protruding from the bed of the river at several points, 
leaving, at low water, dangerous bars but partially concealed, and caus- 
ing rapids and whirlpools, which have proved in years past highly 
destructive to boats. In the course of this important duty, of which 
we hope hereafter to be able to give a full account, the peculiarities of 
the kankar formation, which has been the subject of so much specula- 
tion to Indian geologists, have been strongly impressed on his obser- 
vation, and he has very laudably preserved sketches and remarks of their 
most remarkable appearances in his note-book, which he has now sub- 
mitted with the series of specimens to the Society. <‘‘ They are not 
numerous’’—he writes, ‘‘ having been taken only where differences in 
the kankar and rock were evident, but they forma regular series from 
Agra to Allahabad, shewing the nature of the rocks occurring throughout 
that distance. Having little knowledge of the subject myself, I have 
not attempted descriptions of the specimens, which will be more cor- 
rectly recognized by others, but have substituted what may be of use, 
viz. sketches and notes of the exact situations whence the specimens 
have been obtained. These even amount to little more than indica-
