amongst many remarkable things shown by Members of the 

 Quekett Club, they were informed that "Mr. E.Bartlett caused 

 his microscope to disclose that which lay concealed in the 

 inside of heather," "Mr. T. Simpson enlarged the vision of 

 the human skin," and " Mr. F. A. Parsons illuminated the com- 

 position of bog-moss." The climax was, however, reached by 

 the statement that "in addition to illustrations under the 

 microscope, Mr. C. Jones brought an achromatic spectroscope'' 

 this being what Mrs. Malaprop would call " a nice derangement 

 of epitaphs." 



Mr. Watson exhibited and described a new form of the 

 " Edinburgh Student's Microscope," in which this well-known 

 instrument was mounted upon a tripod base. 



Mr. Karop thought that in the form now shown this was 

 certainly a very nice microscope, but he could hardlj^ see why 

 it should be cat away so much at the back ; possibly this did 

 not actually affect its strength, but it had the appearance of 

 weakening it. 



The Chairman said this microscope had been some time in 

 his possession, having been sent to him specially that he might 

 examine the fine adjustment, which had been somewhat 

 severely criticized at a meeting of the Royal Microscopical 

 Society some time ago. His opinion was asked about it at the 

 time, but he had not then any opportunity of- examining it, but 

 the adverse remarks were then made on the assumption that 

 the fine adjustment was made on the Zentmayer plan, which it 

 seemed had always gone wrong after a short time in ordinary 

 use. It appeared, however, on examination that this differed 

 very materially from Zentmayer's, inasmuch as the groves were 

 thoroughly sprung, so that if it began to show signs of wear it 

 could always be tightened up again by turning the screws. 

 There seemed to be no difference^ in construction between this 

 and the similar pattern of Messrs. Swift, except that the lever 

 in one was placed vertically, and in the other it was at right 

 angles. He considered this to be a very nice instrument with 

 its present stand ; the horse-shoe foot was always very heavy, 

 and for all that it was easily thrown over, so that both for 

 lightness and steadiness he greatly preferred the tripod. 



The Chairman exhibited a simple apparatus for projecting 

 the image of any large object under low power upon paper
