CHEMISTRIES 



By F. W. CLARKE, Chief Chemist of the United States 

 Geological Survey, and L. M. DENNIS, Professor of 

 Inorganic and Analytical Chemistry, Cornell University 



THESE two books are designed to form a course in 

 chemistry which is sufficient for the needs of secondary 

 schools. The TEXT- BO OK is divided into two parts, 

 devoted respectively to inorganic and organic chemistry. 

 Diagrams and figures are scattered at intervals throughout the 

 text in illustration and explanation of some particular experi- 

 ment or principle. The appendix contains tables of metric 

 measures with English equivalents. 



^f Theory and practice, thought and application, are logically 

 kept together, and each generalization is made to follow the 

 evidence upon which it rests. The application of the science 

 to human affairs, its utility in modern life, is also given its 

 proper place. A reasonable number of experiments are in- 

 cluded for the use of teachers by whom an organized laboratory 

 is unobtainable. Nearly all of these experiments are of the 

 simplest character, and can be performed with home-made 

 apparatus. 



^j The LABORATORY MANUAL contains 127 experi- 

 ments, among which are a few of a quantitative character. Full 

 consideration has been given to the entrance requirements of 

 the various colleges. The left hand pages contain the experi- 

 ments, while the right hand pages are left blank, to include 

 the notes taken by the student in his work. In order to aid 

 and stimulate the development of the pupil' s powers of observa- 

 tion, questions have been introduced under each experiment. 

 The directions for making and handling the apparatus, and 

 for performing the experiments, are simple and clear, and are 

 illustrated by diagrams accurately drawn to scale.
