appendix of three pages has been added to this part by Dr. Gr. 

 Johnstone Stoney, F.R.S., dealing with the influence of 

 diffraction on the resolving power of microscopical objec- 

 tives. 



The second portion of the work, by [Mr. Martin Cole, is 

 supplemented by a table of organs and tissues, giving the 

 hardening agent, staining fluid, and mounting medium appro- 

 priate to each ; Mr. Hopewell Smith's process of preparing 

 sections of teeth ; Mr. Rousselet's method of preserving 

 Rotifers; Golgi's nitrate of silver process for nerve cells, and 

 numerous other additions or improvements. Short of actual 

 demonstration, this section of the work will serve as the best 

 possible guide to the would-be preparer and mounter of 

 microscopic objects of whatever class, as might be expected 

 from such an able manipulator as Mr. Cole (How is it that 

 nearly all the text-books and manuals, the present included, 

 will write " Farrant's medium?" Mr. R. Farrants, F.R.C.S., 

 was Qaekett's successor in the Presidential chair of the R.M.S., 

 but he might have lived in the middle-ages from the way in 

 which his name is, and has always been, mutilated.) On its 

 merits "Modern Microscopy" is cordially to be recommended. 



Frederic Kitton : A Memoir. London : Gr. Redway, 9, Hart 

 Street, W.O. Price 2s. 

 A brightly written memoir of our late esteemed Hon. 

 Member by his son, Mr. F. Gr. Kitton, the well-known artist 

 and illustrator of the haunts of Dickens, containing such an 

 account as is possible of a quiet life spent partly and re- 

 luctantly in an uncongenial commercial pursuit and largely in 

 scientific recreation and research. A simple, uneventful career, 

 devoted mainly to the study of Diatoms, things invisible to 

 ordinary sight, can have no meaning or message to the crowd, 

 but those among us who knew him and appreciated his kindly, 

 retiring nature, and had a pass to his store of knowledge on the 

 subjects that he loved, will be glad to possess this filial tribute 

 to his memory. It contains a complete list of Mr. Kitton's 

 contributions to standard works and scientific periodicals, 

 besides an excellent portrait, copies of w T hich, on India paper, 

 may be obtained from Mr. F. Gr. Kitton, Pre Mill House, St. 

 Albans, price Is. 6d,
