MICROSCOPICAL SOCIETIES. 



Quekett Microscopical Club. 



Friday, May 15. — The 342nd ordinary meeting- of this, 

 club was held at 20 Hanover-square, Mr. J. G. Waller^ 

 F.S.A., President, in the chair. The minutes of the pre- 

 ceding- meeting- were read and confirmed, ballot for new 

 members taken, the additions to the library announced," 

 and other formal business g-one through. 



Mr. Miles exhibted specimens of Aulacodisci from 

 Sendai, in Japan, one of which, A. g-ig-anteus, was in almost 

 perfect condition, which is rarely the case. Mr. Enock 

 read a note on two aquatic H3anenoptera — viz., Prestwichia 

 aquatica and Caraphractus cinctus. The former was the 

 first time of capture since 1862, by Sir J. Lubbock. Mr. 

 Enock also gave his reasons for suppressing- the name 

 Polynema natans, as it had been clearly proved by the late 

 Mr. F. Walker that it was identical with C. cinctus of 

 Halliday. Mr. Nunne}^ gave an account of certain disc- 

 like bodies he had found on the stigmal vein of the wing of 

 a Chalcid fly, and the matter was discussed by Mr. Ingpen 

 and Mr. Michael. Mr. Nelson exhibited a portable micro- 

 scope, designed, he believed, by Dr. Ross, and made by 

 Mr. Baker. He also read a paper on "Correcting- Errors 

 in Camera Drawing-s." Mr. Karop read a note on "Illumi- 

 nating- Objects with Low Powers by Artificial Lig-ht." 

 Votes of thanks were passed for these several communi- 

 cations. Announcement of the meetings and excursions 

 for the ensuing month was then made, and the proceed- 

 ing's terminated. The next ordinary meeting will be held 



on June 19.
