fore. Nominations for five vacancies on the Committee were 

 made hj the members and Auditors appointed. 



Mr. D. Bryce read a paper on " Two New Rotifers : Callidina 

 pusilla and C. cornigera.''^ 



The thanks of the Club were voted to Mr. Bryce for his 

 interesting paper. 



Mr. Rousselet read a paper " On a Method of Preserving 

 Various Forms of Pond Life." 



Mr. Western said that Mr. Rousselet had given him oppor- 

 tunities of watching the processes he had described, which he 

 considered very valuable for the purpose, as the members could 

 judge from the specimens Mr. Rousselet was showing that 

 evening. They certainly wanted the charm of life, but it was 

 now possible to keep specimens of Rotifers and such like, which 

 were really valuable for purposes of reference. In some cases 

 the structure was more visible than in the living animal. He 

 had made a few attempts with tolerable success, and he thought 

 anyone with a little experience would not fail to get good results. 



The Chairman considered Mr. Rousselet's extremely useful 

 and interesting paper supplied a great want — a suitable method 

 of preserving Rotifers, etc., in a way resembling what they were 

 in life. While hearing his communication, it struck him how 

 very useful it would be for preserving a great many other 

 structures, such as the Polyzoa and other forms of lower life. 

 He was convinced that for creatures bearing tentacles the 

 process of narcotizing as slowly as they possibly could and 

 then fixing was practically the only process which would give 

 satisfactory results They all knew how absolutely necessary 

 it was to adopt some fixing-agent immediately after death ; 

 what that agent should be depended upon the creature with 

 which they were dealing. Mr. Rousselet's fluid gave very 

 satisfactory results in the case of Rotifers. He moved that the 

 thanks of the members be given Mr. Rousselet for his paper. 



The Secretary read a paper by Dr. Edwards, of New 

 Jersey, U.S.A., "On Some Diatomaceous Earth from Guate- 

 mala." 



Mr. Nelson gave some instances of the enormous distances 

 that volcanic material was projected. 



Mr. Newton said it was very interesting to find probable 

 marine forms of diatoms in fresh- water deposits, or fresh- water
