140 SUMMARY OF CURRENT RESEARCHES RELATING TO 



he inserted this advertisement really believed that he was imparting to 

 his fellow countrymen a sound and valuable piece of microscopical 

 information. 



" Curiosities of Microscopical Literature." — In the last volume of 

 the Journal, p. 830, we had occasion to comment upon a paper by Mr. 

 H. Morland, in which a fundamental point of microscopical optics was 

 the subject of an extraordinary misapprehension. 



In the last number of the publication in which the original paper 

 appeared, we find the following entry : * — 



" Mr. Morland read a reply to a criticism in the Eoyal Microscopical 

 " Society's Journal for the current month on his paper on ' Mounting 

 " Media so far as they relate to Diatoms.' " 



Neither the reply nor even an abstract of it is, however, printed, and 

 no communication has reached us as to the nature of it. This is the 

 funniest way of dealing with a " reply " that we can recall ; it is framed 

 somewhat on the principle of Leech's celebrated cartoon of Lord John 

 Russell chalking " No Popery " on Cardinal Wiseman's door, and then 

 running away !

 Dancer, J. B., Death of. 



[" The death is announced of Mr. John Benjamin Dancer, a Manchester optician, 

 to whom many important inventions are due. Mr. Dancer was born in 

 London in the year 1812. He settled in Manchester in 1835, and soon made 

 Ins mark in scientific circles. He was elected a member of the Literary and 

 Philosophical Society, and a Fellow of the Royal Astronomical Society. He 

 was the first to suggest the application of photography in connection with the 

 magic lantern, and he followed it up by other improvements. He also con- 

 structed the optical chromatic fountain, an idea which has since been further 

 developed at South Kensington, and Old Trafford, Manchester. Mr. Dancer's 

 services in connection with electricity and photography were of a valuable 

 and important nature. Further, Dr. Joule states that the first thermometer 

 made in England with any pretensions to accuracy was constructed by the 

 deceased. He was also successful in producing Microscopes which, while 

 fully equal to the requirements of original research, were within reach of 

 working-men naturalists. During the later years of his life Mr. Dancer's 

 pecuniary circumstances were of a straitened character, and he also suffered 

 from the terrible affliction of total blindness."]
