xiv SCIENCE PROGRESS. 



A Text-book of the Science and Art of Breadmaking. By William Jago, F.I.C., F.C.S. 

 London: Simpkin, Marshall, Hamilton, Kent & Co., Ltd., 1895. 



In Tfie Science and Art of Breadmaking Mr. Jago has given to the world a volume 

 containing an immense amount of information on almost all subjects connected with bread- 

 making. 



Recognising that many of his readers would probably have but scanty scientific libraries 

 to refer to, the author has prefaced the more serious parts of the work with some pages of 

 elementary physical definitions and notes on the properties of the more important chemical 

 elements and compounds. The construction and use of the microscope are shortly described, 

 and then follow chapters in which the carbohydrates and proteids are adequately treated. 

 The important subjects of Enzymes and Fermentation come in for a good share of attention and 

 are treated in such a way as to be intelligible to any one who is likely to refer to the book. 

 The plates in this section are numerous and useful. 



In the chapters on breadmaking, bakehouse design, and flour testing, immense stores of 

 information are laid bare, whilst the section on the cause of and cures for sour bread will be 

 f service to many. 



Altogether we expect the book will take its place as one of the most important 

 works of reference in the hands of those connected with the baking trade.

 und vermehrte auflage. Jena : Gustav Fischer, 1895. 



This convenient little volume forms an excellent manual of histological technology. A 

 very large number of fixing, hardening, and staining methods are described, and a useful 

 chapter on microtomes and microtome knives is also included. The first part of the volume 

 ends with a brief account of the process of reconstructing in wax the form and structural 

 details observed in a series of sections. The second part deals with the practical application 

 of the methods previously described, to the various tissues of different animals. The book is 

 decidedly worthy of commendation, and the author's own notes and criticisms on the many 

 processes described will be valuable to histologists. 



The October number of the Photogram (London : Dawbarn & Ward) contains a useful 

 note on Photographing Coins and Medals ; good reproductions of Photographs of Maori types 

 by A. lies, of Thames, N.Z. ; a continuation of Mr. Charles Gamble's papers on Gums, 

 Resins, Balsams, Oils, and Waxes ; and a specially welcome paragraph on the Photography 

 of the Retina, besides other articles and notes.
