Mr. White said he thought they would be, where acids were used. 

 Mr. Mclntire said that he had used the vulcanite cells, and found tliey had a 

 tendency to chip off the slides after a time. 



Mr. White thought this would very likely be the case, because if the slide 

 were made too hot the vulcanite would melt ; but if not hot enough, the cement 

 would not become sufficiently melted to make them adhere. 



The Chairman proposed a vote of thanks to Mr. Smith for his communication, 

 which was carried unanimously. 



The Secretary, in announcing the meetings for the ensuing month, congratu- 

 lated the members upon the fact that the Club would enter upon the new year 

 18/2 with 560 members upon its list. 



The Chairman said he should be very glad to see a greater number of objects 

 ealiibited at the close of the meetings; they added very much to the life of the
