IT is a practical embodiment of the modern spirit of investiga- 

 tion. It places the student in the position of an investigator, and 

 calls into play mental faculties that are too often wholly neglected. It 

 leads him to observe, to experiment , to think, to originate. Coming as 

 it does from the working laboratory of a practical instructor, who has 

 had the constant advice of fellow-teachers in all parts of the country, 

 this text may be fairly taken as an exponent of the latest methods of 

 teaching chemistry. 



Its distinctive features are: experimental and inductive methods; 

 the union of descriptive and qualitative chemistry, thus allowing these 

 kindred branches to supplement and illustrate each other ; a practical 

 course of laboratory work, illustrating the general principles of the 

 science and their application ; a fair presentation of chemical theories, 

 and a conciseness which confines the work to the required limits. 



Each element and compound is treated in the following natural 

 manner : — 



1. Its occurre7ice, in which the student learns where he may find it. 



2. Its preparation, or how he may obtain it for examination. 



3. Its properties and uses, 



4. Its tests, or how he may detect its presence in known or in un- 

 known substances. 



Many equations are given to illustrate the chemical reactions in the 

 different operations, and there are also special directions for detecting 

 the acids as well as for separating the metals into groups, and isolating 

 the individuals from each group. 



The work closes with full and explicit directions for successfully and 

 economically equipping the laboratory, and preparing the needed re- 

 agents and solutions. 



Teachers who are compelled to compress their work into a few weeks' 

 course can adopt the " Briefer Course " outlined in the preface, and 

 have meanwhile the benefit of a book sufficiently complete to cover any 

 want likely to arise in the laboratory. But average pupils of sixteen 

 years can do all the work laid down in this text. A fair class can do the
