PROCEEDINGS OF THE SOCIETY. 381 



The Chairman said that a very excellent exhibition of living aquatic 

 objects had been arranged for that evening, and he would ask those 

 Fellows who were not exhibitors themselves, to pass a special vote of 

 thanks to those who were. Their thanks were also due to Members of 

 the Quekett Club who had kindly brought their Microscopes, and were 

 exhibiting examples of pond life. 



The vote of thanks having been put from the Chair, was carried 

 unanimously. 



The Chairman said that they had no formal papers to be read at 

 the Meeting, and he, therefore, now had only to invite those present to 

 examine the objects exhibited, which he was sure would prove to be of 

 very much interest to all.
