artificial origin. With this intention I examined on the Therria coal 

 field, various heaps, and spreads of pebbles derived from the conglo- 

 merates which are so characteristic of the Lower Damoodah series of 

 rocks. These pebbles consist of gneiss, quartzite and sometimes even 

 granite ; a large proportion of them are jointed, or perhaps to speak 

 more correctly cracked, the planes of easy fracture being inclined at a 

 small angle to the major axis. Supposing several of such planes to 

 co-exist in a pebble, a smart blow at either apex would produjpe a 

 disunion of the parts, and a stone would be the result which might 

 be mistaken for a bona fide implement ; but such a stone would lack 

 the chipped appearance which all those of undoubted artificial origin 

 possess. No. 3 of my collection may have been the result of natural 

 causes; but it is difficult to conceive any natural causes by which 

 such a symmetrical form as No. 1 could have been produced, and the 

 same applies but in a less degree, to No. 2. 



To describe the several implements in detail. 



No. 1. So made from a pebble of greenish quartzite, upon one side 

 the original surface is still seen. While resembling some of the Madras 

 specimens, it differs from all of them that I have seen in the ratio which 

 its thickness bears to its length amounting as it does to J. Its strength 

 suggests that it may have been used in the manufacture of others. It 

 was found upon the surface near the village of Kunkune, 11 miles 

 S. W. of Govindpoor on the Grand Trunk Road. 



No. 2. Is made of a micaceous quartzite, it resembles closely some 

 of the Madras specimens ; in it also there is a face consisting of the 

 original surface. It was found by Mr. Hughes in the Boeharo coal field. 



No. 3. Is of doubtful artificial origin : its shape suggests that it 

 may have been used as a spear or dart -head. It was found not far 

 from the locality given for No. 1. 



It is not improbable that more extended investigations in the 

 neighbourhood of the localities given, may bring abundance of these 

 implements to light. It will be interesting to find in Bengal, evidences 

 such as have been found in other parts of India of an early primitive 

 race of men.
