THIS brief course is prepared on the same plan as the author's Ele- 

 ments of Inorganic Chemistry, published some four years ago. 

 The book is not a fragmentary compilation, but gives the student a 

 concise and comprehensive view of the main formulas of chemical 

 science. The experiments are easily performed and bear directly upon 

 the subjects under consideration. The apparatus and chemicals re- 

 quired are as inexpensive as thorough work will permit. It is well 

 adapted to the needs of schools where the time is limited and 

 where the teacher aims to do most of the work, but it will find a warm 

 welcome in schools possessing working laboratories. 



The Organic portion, although strictly elementary, includes some- 

 thing more than the detached and disconnected chemistry of a few 

 important compounds. Enough of the principles underlying organic 

 chemistry are introduced to enable the student to obtain a general 

 knowledge of how organic substances originated and how they are related. 

 At first a general view of the hydrocarbon series is given and then 

 one or two members belonging to the parraffin series are taken up at 

 sufficient length to illustrate the important classes of derivatives which, 

 in general, belong to each hydrocarbon series. After this only the 

 most important members of the remaining series are noticed. 



Since the analytical features of organic chemistry present too many 

 difficulties for beginners with limited time, nothing of the kind has 

 been attempted. But the experimental work is sufficiently easy to af- 

 ford profitable work even in laboratories with limited facilities. 



The following letters received soon after the publication of the book 

 are indicative of the favor "with which it has been received. 



C. E. Boynton, Senior Teacher, 

 Chicago Manual Training School : I 

 think the bock in some ways an improve- 

 ment on the old, but for our course it is 

 too brief, so we shall continue to use the 

 larger book. 



D. L. Bardwell, Teacher of Sci- 

 ences, State Normal School, Cortland, 

 N. Y. : I am particularly struck with the 

 simplicity of the apparatus generally 

 used, and above all, the suggestiveness of 

 the experiments. (Oct. 2, 1890.)
