club together formations that have long since been distinguished ; as for 

 the great Gondwana rock-system, of which on such a map, we can only show 

 an upper and lower division ; or for the Vindhyan formation, the many 

 sub-divisions of which have all to appear under one colour. But, as I have 

 stated, this majD is only an index ; and for many important areas, special 

 maps have already been published. 



Me. V. Ball exhibited two stone implements from Parisnath Hill 

 (District Hazaribagh) and said : — 



The two stone implements which I exhibit were received by me from 

 Mr. I. J. Whitty, of Giridi. They are reported to have been found during 

 the clearance of the primeval forest on the northern slopes of Parisnath 

 Hill, where a tea garden has recently been oj)ened out. 



Differing from those which I exhibited from Singhbhiim* and which 

 were interesting as being of the specialised Burmese type, the present speci- 

 mens (and particularly the larger one) conform to more ordinary types of 

 polished celts, examples of which have been met with in most of the coun- 

 tries of Europe and elsewhere. 



As is not unfrequently the case with polished celts, the material of 

 which these are formed is a volcanic (trapjjean) rock. The large specimen 

 was probably a battle-axe, while the small one, with its carefully ground 

 edge, was no doubt used as a scraper for dressing skins of wild animals, 



I hope to hear soon whether any further examples have been obtained 

 from the same locality. In the meantime it is desirable to place on record 

 this new locality. 



The following papers were read — 



1. ITote on certain peculiarities ohserved in Hailstones ichich fell at

On the above date there was an extraordinarily heavy fall of hailstones 

 of rather considerable size, some being as large as a goose's e^^. Of 

 course these latter were not single stones, but compound ones, as none of 

 the former are known to attain a larger bulk than that of a pigeon's egg. 



As regards the majority of these large stones, their form and structure 

 were rather peculiar. They appeared to be of a discoid form, and their 

 surface was extremely irregular and jagged. From a more or less transpa- 

 rent nucleus about the centre, issued concentric rings of different degrees 

 of opacity, which were very clearly discernible. These peculiarities I have, 

 however, observed before, and I need not describe them more closely, as 

 they are doubtless known to others.
