INDEX TO THE PLATES. 



Plate I. — The first Implement discovered at Palaveram 10 miles S. W.

 quartzite from the Atrumpakkam nullah, of the same type as that figured

 compact quartzite. 



Plates V and Va. — A large Implement from Moderimbedu, near

 shown in plate VI a. 



Plates VII and Vila. — A large and rather rude, lon# oval, broad pointed ;
