bended greatly to lengthen the process, and this also he considered should 

 lie avoided as far as possible. In his method the material could be 

 inserted in the apparatus, ground without the addition of any extraneous

The President considered that his would-be objections had been 

 effectually answered, and proposed that the thanks of the Society be 

 accorded to Mr. Barnard for his communication. 



The vote of thanks to Mr. Barnard was unanimously carried. 



In regard to Mr. Batcher's paper on " Structural Detail of Coscino- 

 discus asteromphalus," the President said that the subject opened up so 

 large a held for discussion from the microscopic and optical point of 

 view that Mr. Butcher nad kindly consented to postpone the paper until 

 the October Meeting, when other opinions would be obtainable on this 

 very important subject. He proposed that Mr. James Murray's paper 

 on " Rotatoria of some Pacific Islands " should be taken as read, as the 

 rest of the Meeting would be taken up in examining the exhibition of 

 pond-life before them. He wished to express the thanks of the Society 

 to Members who had assisted in bringing together so many beautiful and 

 interesting specimens.
