Page 83. The evidence in favor of a (geologically) recent very gradual eleva- 

 tion of the Coast, in the District of Cuttack, has been alluded to above. But this 

 evidence is by no means limited to this district, and the same reasoning is confirmed 

 by more extended researches along the entire shore of the Peninsula. In many 

 places, the occurrence of marine shells, of existing species, in great plenty, at consi- 

 derable distances from the present sea shore, renders this evidence more obvious 

 and more conclusive. During a recent visit to Madras, I had an opportunity of 

 seeing some of these and, by the kindness of Dr. Balfour and of Dr. Hunter, of 

 procuring a tolerable series of such shells which are of great interest. All of those 

 which occur in the surface deposits, although at some distance from the shore and 

 quite beyond the reach of the sea at present, appear to be of species now existing, 

 and known to occur in the living state in the vicinity. But under the surface sands 

 and clays, at irregular depths according to locality, there occurs a bed of dark-blueish 

 clay or silt, which contains numerous shells, often partially decomposed, and among 

 these there are more than one species not now known to occur on the Madras Coast, 

 although still existing in the present seas. The most remarkable of these is the 

 Placuna placenta, of which specimens are abundant, but which is not now found 

 on that part of the shore of the Bay of Bengal. 



Detailed examination of these deposits, and of the remarkable shelly sandstones, 

 extending for many miles along the Coast near the Southern extremity of the 

 Peninsula, will doubtless add much to our present knowledge on these points, and 

 will, in all probability, enable us to decide, not only the fact of the elevation of these 

 shores in modern times, but also the character of that elevation, its relative amount 

 in various localities, and the extent of area over which it has occurred.
