Two very valuable works on this most important subject, which we 

 unhesitatingly state are treated in a most thorough manner. Thus we find the 

 Manual iirst describes the Histological apparatus required in Bacteriological 

 research, the Microscope and its accessories, and the Microtome. The various 

 reagents and materials employed in hardening, decalcifying, embedding, 

 fixing, and cutting of tissues ; for examining and stainijig microscopical 

 preparations, and for mounting and preserving preparations ; apparatus for 

 drawing and photographing; for sterilisation; for preparing and storing gelatine, 

 etc., and for employment of nutrient jelly in test tube anil plate cultivations ; 

 fur the preparation of potato cultivations ; of solidified sterile blood serum ; 

 for storing, and for cultivations in liquid media ; and for incubation, etc. ; 

 followed by chapters on the microscopical examination of Bacteria in liquids, 

 in cultivations on solid media, and in tissues ; on the preparation and staining 

 of tissue sections ; the preparation of material ; media and methods of cultiva- 

 tion ; and experiments upon the living animal, etc. Part II. treats of the 

 General Biology of the Bacteria, and Part III. is systematic and descriptive. 

 In this work there are 29 beautifully coloured plates, in addition to 137 engrav- 

 ings in the text, many of which are coloured. 



The Photography of Bacteria treats mainly of the 

 photography of the subject ; chapter I. opening with a short historical sketch of 

 the a]Dplication of Photography, Micrography, the difficulties presented by 

 stained specimens, and the reasons for resorting to Photography ; chapter II. 

 describes the apparatus and material ; chapter III., the practical manipulation ; 

 and chapter IV., reproduction from negatives, etc. In addition to the very fine 

 autotype plates, there are 6 excellent wood engravings describing the various 

 photographic ajjparatus.
