PROCEEDINGS OF SOCIETIES. 113 
scopist, in bringing this subject before the Society. As I have 
before stated, I do not attach so much importance to the mate- 
rials employed as to the method of preparing them. The method 
I propose has been found very good in many cases; Mr. Hall’s 
proposed method of dipping would be excellent; and I think the 
two might be very well worked together. What I wish, however, 
particularly to say is, that in every case, after the cell has been 
mounted on the thin glass, it should be properly finished with 
marine glue or cement or gold size outside; and if that is done, 
I do not see how damp can affect it. Ido not put the cell on 
and leave it, but always properly cement it, and in that case I 
do not think it can be reached by moisture. 
The discussion was concluded, and a vote of thanks was pro- 
posed to Mr. Smith and Mr. Beck, which was duly carried. 
A paper from EH, Ray Lankester, Esq., “ Notes on the Gregari- 
nida,” was read. (‘Trans.,’ p. 23.)
