THIS course is designed to meet the wants of all secondary 

 schools, and to provide a satisfactory text, a sufficient 

 amount of individual laboratory v^ork, and suitable 

 lecture-table demonstrations. It is an entirely new book, con- 

 taining the results of the most recent scientific investigations, 

 and constructed in accordance with modern methods of 

 teaching this subject. The work has been arranged as 

 attractively as possible, especially at the beginning, in order to 

 secure and develop the interest and enthusiasm of the pupil. 

 Clearness and accuracy of statement mark the definitions, 

 directions, and explanations. The experiments are simple 

 and instructive, easily performed, and adapted to the use of 

 inexpensive and easily obtainable apparatus. 

 ^ Unusual space is devoted to chemistry as applied to im- 

 portant industrial processes, such as the manufacture of gas, 

 iron, steel, soap, soda, etc., the refining of petroleum, etc. 

 In fact, every important modern topic pertaining to the science 

 is taken up ; the practical application of chemistry to the affairs 

 of everyday life, such as the contamination of water, bread 

 making, the fertilization of soils by the action of nitrifying 

 bacteria, etc., is given due attention. 



^ The treatment of hydro-carbons in series (including the 

 "organic" compounds of the old chemistry) is unusually 

 full, systematic, and simple. The periodic law is here for 

 the first time in an elementary text-book given full statement, 

 clear explanation, and the obedience to which it is entitled.
