2 Mr. R. Bruce Foote on the occurrence of 



including them within the group of Quarternary or possibly 

 even Recent deposits(l). 



These implement-bearing-formations so far as they have 

 hitherto been examined in the Madras and North Arcot 

 Districts are found resting either on the older metamorphic 

 rocks of the country, the Gneissic series, or more generally 

 on a series of formations probably of greater geological an- 

 tiquity than the Cretaceous system. These formations 

 provisionally termed the Stri Permatoor series, because of 

 their having been first studied near the town of that name 

 contain vegetable remains which appear to be identical in 

 species with some discovered in the Rajmahal hills in Ben- 

 gal and also in Cutch. These latter fossil plants are thought 

 to have affinities to, even if they be not absolutely identical 

 with certain forms occurring in the Jurassic formations of 

 Europe. 



All the Implements that I have seen hitherto, amounting 

 to several hundreds, are made of quartzite — which is a 

 metamorphosed sandstone, generally semi- vitreous in tex- 

 ture, very hard and tough, and, on the whole the best sub- 

 stitute for flint in this part of India. 



The first Implement discovered was found by me on the 

 30th May last year, among the debris thrown out of a small 

 gravel pit a few hundred yards north of the Cantonment 

 at Palaveram (10 miles S. W. of Madras) and about the 

 same distance west from the high-road. My acquaintance 

 with the flint Implements which have excited so much in- 

 terest in Europe was at that time limited to figures of them 

 given in " The Geologist," and I was then but little fami- 

 liar with peculiarities of fracture of quartzite pebbles. I 

 felt a little doubtful therefore in unhesitatingly regarding 

 my find as a genuine Stone Implement, so contented myself 



(1.) Note.— The term Recent deposits is intended to embrace all in 



Tfliich the included organisms are of living species.
