so as to enable either the flat or the edge of the flame to be 

 used, and it should have an iron chimney holding- an ordin- 

 ary 3 in. glass slide, to be readily and cheaply changed if 

 cracked. Such a lamp would cost about $6. A reflector is 

 worse than useless, as it confuses the light rays. — Sci-Gos. 



MICROSCOPICAL SOCIETIES. 



Quekett Club.— The 372nd meeting on Friday, Nov. 17th. 

 Dr. J. Tatham, M. A., President, in the chair. A series of 

 photographic reproductions of the plates in Ehrenberg's 

 "Radiolaria from Barbados," published many years ago as 

 a supplement to the "Mikrogeologie," and now scarce, was 

 presented by Mr. Mottram. Messrs. Bakerexhibited Leitz's 

 new travelling or portable microscope, with folding base 

 and removable stage, coarse adjustment by rack, fine ad- 

 justment on the Roberval plan, Abbe condenser and Iris. 

 Mr. A. Earland read an elaborate paper on the "Radio- 

 laria or Polycystina," dealing with their classification, mor- 

 phology, physiology, and distribution. 



Royal Society. — At the meeting on Nov. 15, Dr. Hebb 

 called attention to the Volume of the Transactions of the 

 Jenner Institute of Preventive Medicine, which he thought 

 would be of great interest to those engaged in bacteriolo- 

 gical work. Mr. C. L. Curties exhibited a new form of por- 

 table microscope by Leitz. It had a folding foot and a re- 

 movable stage, to enable the instrument to be packed in a 

 small compass. The body was not made to incline, but was 

 furnished with a coarse and fine adjustment, and the stage 

 was fitted with a modified form of Abbe condenser with 

 Iris diaphragm. The President thought the instrument 

 would be useful to those requiring a very portable one; its 

 great compactness was effected in an ingenious manner, 

 while the working parts were well made and finished. The 

 President read a short note descriptive of a set of three 

 simple hand-microscopes, on the Coddington principle,sent 

 for exhibition by Mr. Edward Swan. They were appa- 

 rently made for a medical man, and could not be very old.
