Modern Microscopy. By M. I. Cross and M. J. Cole. 3rd edit. 

 Demy 8vo. pp. xvi + 292 ; 76 illustrations. London, 1903 : 

 Bailliere. Price is. net. 



The new edition of this work well sustains the reputation its 

 predecessors acquired as an excellent introduction to general 

 microscopy; moreover, it has been increased by some 110 pages. 

 The first part, by Mr. Cross, dealing with the instrument and 

 its accessories, remains much the same as before, except that 

 some few obsolete types are omitted and some newer ones 

 introduced. The second part, by Mr. Cole, has been thoroughly 

 revised and brought up to date, and remains one of the very best 

 guides to the preparation, staining, and mounting of microscopic 

 objects extant in a limited compass. An entirely new and useful 

 section has been introduced in this edition on " Microtomes : their 

 Choice and Use," by Mr. G. West, of the Botanical Laboratory, 

 Edinburgh. This should be of great assistance to the beginner, 

 who is most frequently bewildered by the multiplicity of these 

 indispensable instruments. He will find here practical directions 

 as to the suitability of the various types to different classes of 

 work, the methods of embedding and cutting, from the simplest 

 to the most elaborate ; in fact, all the information a comparatively 

 brief exposition can be expected to afford. As was said of the 

 previous edition, it is a work that can be cordially recommended.

 whilst nearly all have been brought up to date by the intro- 

 duction of new matter.
