GEOLOGICAL SURVEY OF INDIA. 



On the Cretaceous and other rocks of the SouTH Arcot, and 

 Trichinopolt Districts, Madras. By Henry F. Blanford, 

 Geological Survey of India. 



Part I. 

 Chapter I. — General Summary of previous researches. 



Historical Summary.— The fossiliferous rocks of the Carnatic were 



first brought to the public notice by the late 

 Mr. Kaye, 1840. 



Mr. Kaye, of the Madras Civil Service, who, in 



company with Mr. Brooke Cunliffe, collected a large series of fossils from 

 the limestone beds of Pondicherry and Verdachellum, and by the 

 co-operation of Mr. Onslow, in Trichinopoly, obtained a further series from 

 the shell limestone occurring in that district some miles to the South of 

 Verdachellum. Mr. Kaye's first published notice of his labors appeared 

 in 1840, in the 28th number of the Madras Journal of Literature and 

 Science,* wherein he gave a general resum^ of the results of his investi- 

 gations up to the date of publication. In this paper, Mr. Kaye describes 

 the limestone beds at Sudarampet and their topographical position 



* In this paper Mr. Kaye mentions some letters wliich had appeared shortly before in the 

 Madras Spectator Newspaper. These I have not seen, having been unable to procm-e 

 a file of the Newspaper of that date, nor have I been able to learn with any certainty who was 

 their author. From the way in which Mr. Kaye speaks of them, and from the fact that they 

 appeared, while he was engaged in prosecuting his researches on the spot, I think it most 

 probable that they were from his pen, or at all events that he furnished the materials.
