Ordinary Meeting, February 26th, 1907. 

 Professor H. B. Dixon, M.A., F.R.S., in the Chair. 



The thanks of the members were voted to the donors of the 

 books upon the table. 



Professor H. B. Dixon, made reference to the recent death 

 of an Honorary Member, Professor Henri Moissan, whose fame, 

 he said, rested on his being the first to isolate fluorine and to 

 prepare artificial diamonds. 



Dr. R. S. Hutton added that Moissan had more than once 

 expressed his appreciation of the honour conferred upon him 

 by the Society in electing him an honorary member at a time 

 when his work had not obtained general recognition. 



Mr. Thomas Kay, of Stockport, read the following com- 

 munication : — 



I have to shew you a piece of new red sandstone of this 

 district picked up above the clay in the camp site of Mancunium 

 which is somewhat remarkable, for it was picked up out of the 

 black soil and rubbish dug out of the place where the Roman 

 Vase was found — and it arrested my attention by its distinct 

 character from all the other stones which were of a gravelly 

 nature in the heap. 



Only after washing and scrubbing it was its true nature 

 discovered. 



At first I thought it was part of a whetstone, a sharpener for 

 swords and polisher of metal, as I find that the fine particles 

 form an excellent scouring medium.
