The Urinc^ The Cojnmon Poisons^ and the Milk. By J. W. Hol- 

 land, M. D. 3d ed. 84 pp. 33 figures. P. Blackiston, Son & 

 Co., Philadelphia. (Price, $1.) 



We are glad to note that the syllabus is rapidly gaining ground in 

 nearly all well-established schools and colleges. It has long been held 

 by the best authorities on Biology, Chemistry, and Physics that the way 

 to gain the greatest knowledge of any of these sul)jects is not by learn- 

 ing bookish theories but by practical analysis in the laboratory. 



The text of the present syllabus is brief, and at the same time it con- 

 tains all that is really necessary for the mastery of urinary analysis. 

 There are three main divisions of study mapped out, namely : The Ex- 

 amination of Morbid Urine, the Examination for Common Poisons, and 

 the Examination and Study of Milk. Each of these comprehends a 

 score or more of topics. The plan of study is progressive, but at the 

 same time the subjects are treated in a manner which enables the stu- 

 dent to begin with either of the main divisions. The illustrations, 

 many of which are of microscopic views, are a good feature of the 

 book. Leaves are left blank for calculations, memoranda, and addi- 

 tional notes which the student may wish to preserve. The text is 

 printed in two sizes of type ; the more important matter is in larger 

 type, for the convenience of those whose course of study is limited 

 by lack of time, while for those students who wish to gain a more 

 thorough knowledge, many explanations and quantitative processes are 

 given in the smaller type. Every physician should find this a very 

 useful compendium. — R. W. S.
