containing vessel, he never succeeded in rearing the young to their 

 full size, though some that he showed at the Royal Microscopical 

 Society were, to the best of his recollection, at least |" in length. 

 He had tried to find some more mud of the same sort, but had 

 never succeeded. He hoped Mr. Shephard might be able to send 

 him some. Professor Hartog then gave an interesting account 

 of the mode of feeding in the case of Apus and Daphnia (see 

 ante, p. 157). 



Mr. Shephard said he should be very pleased to send some mud 

 to Professor Hartog, but he could not guarantee that it would 

 produce Entomostraca. He had usually kept the mud in an open 

 vessel out of doors, but found it best to bring it indoors during 

 the very dry weather. 



On the motion of the Chairman very hearty votes of thanks 

 were then passed to Mr. Shephard and to Professor Hartog for 

 their communications. 



Mr. W. Wesche read a paper on a new male rotifer found at 

 Golder's Hill, which he referred to Metoindia solidus. 



Mr. Pousselet said it was satisfactory to know that they were 

 becoming acquainted with the males of so many species ; but the 

 male of Philodiyia had not yet been found. 



Mr. Karop said he had received a very excellent paper on 

 ^'The Microstructure of Metals and Alloys," by Mr. Sydney W. 

 Smith, A.R.S.M., which would be taken as read and be printed 

 in the Journal. 



Mr. Karop said that the meeting of that evening was the last 

 ordinary meeting of the session, but the members could meet as 

 in former years on the usual nights, which would be considered 

 as " gossip nights." He thought all the members would agree 

 wdth him that the session now closing had been a very pleasant 

 and instructive one ; he certainly thought that the meeting of 

 that evening had been a very good one, reminding him of the 

 Quekett of the past. He wished the members a very pleasant 

 vacation, and hoped when they met again in October they would 

 hear what some of them had been doing, 



The meeting then terminated with the usual conversazione.
