REPORTS OF SOCIETIES. 201 



evening, and it was now his duty to vacate the chair in favour of 

 his successor, who, he felt sure, would be more an ornament to it 

 than he had been. 



Mr. Hammond, the President for the ensuing year, then took 

 the chair. 



Mr. CuRTiES said it occurred to him that on the eve of Dr. 

 Brown's departure from the chair, they should offer him their very 

 cordial thanks for the work he had done during his term of office, 

 and at the same time express their good wishes for the future. He 

 trusted that, although resigning the presidency, he would continue 

 to exert his influence to advance the interests of the Society. 



Mr. Maynard^ in seconding the motion, said they were all 

 fully aware of the great service Dr. Brown had rendered to the 

 Society. 



The motion was put and carried by acclamation. 



Dr. Brown thanked the members very much for the kind 

 way in which they had spoken of the small services he had been 

 able to render during the year. The duties of the office had not 

 been heavy, but had led him to take greater interest in the 

 working and welfare of the Society. He was sure his interest 

 would not diminish. He hoped the Postal Microscopical Society 

 would continue to prosper. 



The new President, Arthur Hammond, Esq., F.L.S., then 

 proposed the toast of the evening, " Success to the Postal Micro- 

 scopical Society," which was drunk with enthusiasm. 



The President then delivered his address, the subject of 

 which was " The Anatomy and Life-History of the Water-Flea, 

 Daphiia Pulex^'' and was illustrated by a great number of large 

 diagrams, specially prepared for the occasion, but owing to the 

 advanced hour, he was compelled to pass over some interesting 

 features. The address will be found m extenso in the current 

 number of the Journal. 



The Rev. E. T. Stubbs expressed great pleasure in listening to 

 the President's interesting address. He remarked that there was 

 great difficulty in getting the Daphnia into a suitable position for 

 examination, as described by the President. It was usually seen 

 lying upon its side ; but it was necessary to get an endwise view 

 of it, looking towards the rectum, front of the head, and back of 

 the head. The examination of the Daphnia in those positions 

 would add immensely to the knowledge of the animal. He found 

 it very easy to get the Daphnia into other positions by placing 

 them between two slips of wood, pieces of matches pared down, 

 so as to fit inside a thin zoophyte trough, Two such parallel
