WINTER SESSION. 



Note. — The Authors of the various Papers, of which abstracts are here appended, 

 are alone responsible for the views expressed in them. 



HE Winter Session was opened by a conversazione in 

 the Museum, College Square North, on the evening of 

 Friday, the 20th of October, at which a large number 

 of the members and their friends were present. The ordinarily 

 sombre aspect of the Museum was enlivened by a profusion of 

 flags, evergreens, and bouquets of flowers, kindly given or lent 

 by the numerous well-wishers of the club and its work. Of 

 recent years the members of the club have always selected some 

 special subject for illustration at their conversazione. On this 

 occasion it was silica in its various forms, and a table was filled 

 with specimens, ranging from the gigantic flints (or para- 

 moudras) of our local quarries to beautifully cut and polished 

 agates, cairngorms, carnelians, and other precious stones, mak- 

 ing altogether a very attractive and instructive display. There 

 were, in addition, a few samples of its application in manufac- 

 tures, particularly some non-conducting silicate cloth and fibre 

 exhibited by Mr. D. Anderson, of the Lagan Felt Works.
