it is hardly possible to speak too highly : the whole of these 

 have been prepared from Mr. Michael's own drawings from 

 the objects themselves ; and to any one acquainted with his 

 exceptional skill both as an observer and a draughtsman, it 

 will only be necessary to say that the illustrations in this, his 

 latest published work, fully sustain his previous reputation. 

 The way in which these very beautiful drawings have been 

 reproduced and printed leaves little to be desired. The letter- 

 press is also remarkably clear, and so free from typographical 

 errors that Meguin for Megnin on page 4 is almost the only 

 slip at present noticed. K. T. L. 



The Microscope. An Introduction to Microscopic Methods and 

 to Histology. By Prof. S. H. Gage. Eighth Edition ; 9| x 

 6 in., vi -f 299 pages, 230 figs., and a table of natural sines. 

 Ithaca, N.Y., 1901 : Comstock Publishing Co. Price SI. 50. 



This, the latest edition of Prof. Gage's well-known work, is kept 

 thoroughly abreast of modern ideas, and is an excellent text-book, 

 particularly for those going in for a laboratory course, but, at the

 general microscopist. The optical principles are concisely and 

 intelligently stated ; the u?e of most, if not all, really necessary 

 appliances for observation and preparation are well, though briefly, 

 described and figured, while photo-micrography, projection, fixing, 

 embedding, section-cutting, staining and mounting, receive 

 adequate treatment within the limits and purpose of the work. 

 A very useful bibliography and list of periodicals relating to the 

 microscope and microscopical work is appended. G. C. K.
