Letters from Prof. Hermann Fol, of Nice, and Prof. Sir Joseph 
Lister, Bt., F.R.S., expressing their thanks to the Society for the 
honour of their election as honorary Fellows, were read to the meeting. 
Prof. Bell, in calling special attention to the two volumes presented 
by Mr. Burgess, remarked that they formed together one of the largest 
of the reports resulting from the “ Challenger ” Expedition, and con- 
sidering the mass of material from which they had been compiled, and 
the manner in which the work had been done, they not only formed a 
monument to the memory of their late honorary Fellow, Mr. H. B. 
Brady, but would also be a most valuable addition to the Society’s 
library. 
Mr. Mayall said they had received a letter from a correspondent in 
America — Mr. J. H. Noblit — asking for information as to working with 
high powers on opaque objects. He hoped some Fellow who had 
experience in such matters would undertake to reply to this communi- 
1891.
