The President announced that Mr. Hainworth had been appointed Auditor 

 on behalf of the Committee, and requested the members to select another 

 gentleman to act with him in that capacity, on behalf of the Club. 



Mr. Dobson was then proposed by Mr. Guimaraens, seconded by Mr. Brown, 

 and duly elected. 



A paper by the Rev. J. Bramhall, " On a New Oblique Illuminator," was 

 read by the Secretary, who afterwards further explained the principles upon 

 which the instrument was constructed, and the method of using it, by means 

 of diagrams drawn upon the black board. 



Mr. Curties, in reply to a question from the President, stated that he had 

 not employed this illuminator by lamp-light, but by sun-light he had ob- 

 tained results which were very satisfactory. 



The President enquired whether dark-ground illumination could be got by 

 it with high powers ? 



Mr. Ingpen said he had obtained a black ground with a i in. by lamp- 

 light. 



The President thought the effect must resemble very much that of an 

 Amici lenticular prism ; he was, however, of opinion that one great difficulty 

 existed in all these methods of illumination from beneath, namely, that in 

 most cases the objects examined had markings below as well as above, and 

 a false impression often arose from seeing the one through the other ; so 

 that nothing would give them a perfect idea of the real surface but good 

 opaque illumination. He was quite sure that terrible confusion arose in 

 consequence of the two sets of markings being seen at the same time. 

 This new mode of illumination, however, was likely to be very useful in 

 many cases, and one of its merits certainly was its simplicity. 



A vote of thanks to Mr. Bramhall for his communication, was unanimously 

 passed. 



A paper by Mr. Fullagar on TubicolariaNajas,wsiS read by the Secretary. 

 It was illustrated by some very beautifully executed drawings, which were 

 handed round for the inspection of the members. 



The President thought this a most admirable and suggestive paper. He 

 was not aware of any other case in which an ovum had developed in the 

 manner described. The acuteness of observation displayed, and the delicacy 

 of the drawings, were, to his mind, beyond all praise. 



A vote of thanks to Mr. Fullagar, for his paper, was unanimously passed. 

 Mr. Badcock said he had found this object at Walthamstow, in a pond where 

 Conochilus was also found ; it could be obtained there by dredging up some 

 moss from the bottom of the pond. 



Mr. Ingpen said that Mr. Fullagar gave his attention to these animals 



in the intervals of business, and kept them under view for long periods of 



time ; observations conducted in this way could hardly fail to be of great use. 



Mr. Fitch said that, at the suggestion of the President, he had introduced
