was necessary for two auditors to be selected that evening, and 



on behalf of the Committee they had appointed Mr. Bryce. 



He now asked the members to appoint another on behalf of 



the Club. 



Mr. W. Chapman was proposed by Mr. Allen, and seconded 



by Mr. Burton, and unanimously elected. 



Mr. C. Rousselet read a paper " On the Preparation of 



Rotifers as Permanent Microscopic Objects," supplementary 

 to a communication on the same subject made about two years 



ago, and detailing the improved methods discovered and 

 adopted in the meantime. The paper was illustrated by the 

 exhibition of a large number of slides under microscopes in 

 the room, and Mr. Rousselet announced his intention to present 

 to the Cabinet of the Club a complete type collection of every 

 species. Already he had successfully mounted 130 species, and 

 he presented to the Club that evening 77 slides, representing 

 72 species, as a first instalment of his promised donation. 



The President thought they were extremely fortunate in the 

 possession of such an active member as Mr. Rousselet, who 

 had thrashed out the subject of fixing and mounting these 

 very difficult objects so thoroughly, and had given a descrip- 

 tion of the process in a way which would always associate it 

 with the Club. It was hard work, like that which had been 

 described, which would always do more than anything else to 

 keep up their reputation. Their best thanks were due to Mr. 

 Rousselet for his paper, and also for the valuable donation 

 made that evening, and for the promise of a completion of the 

 series in due course. 



Thanks to Mr. Rousselet were unanimously voted. 

 Mr. Goodwin communicated a note on an Alga found at Wan- 

 stead Park on October 5th, at the edge of the pond, which 

 seemed to him to be a new species of Oscillaria. The filaments 

 were very small, and the endochrome appeared green by trans- 

 mitted light, but under the microscope it was difficult to say 

 exactly what colour it was, the endochrome being very much 

 concentrated. So far as he could make out, it was a new 

 species, but he had not yet taken the opinion of any specialist 

 on this point, though he thought if it turned out to be new it 

 was worth recording. No new features had been developed in 

 it since the date on which it was found.
