Introduction to Chemical Science. 



By R. P. Williams, Instructor in Chemistry in the English High 

 achool, Boston. 12mo. Cloth. 216 pages. By mail, 90 cents; for 

 introduction, 80 cents. 



npHIS work is strictly, but easDy, inductive. The pupil is stimu- 

 lated by query and suggestion to observe important phenomena, 

 and to draw correct conclusions. The experiments are illustrative, 

 the apparatus is simple and easily made. The nomenclature, 

 symbols, and ^^Titing of equations are made prominent features. 

 In descriptive and theoretical chemistry, the arrangement of sub- 

 jects is believed to be especially superior in that it presents, not 

 a mere aggregation of facts, but the science of chemistry. Brev- 

 ity and concentration, induction, clearness, accuracy, and a legiti- 

 mate regard for interest, are leading characteristics. The treat- 

 ment is full enough for any high school or academy. 



Though the method is an advanced one, it has been so simplified 

 that pupils experience no difficulty, but rather an added interest, 

 in following it. 



The author himself has successfully employed this method in 

 classes so large that the simplest and most practical plan has 

 been a necessity. 



Thomas C. Van Nuys, Professor 

 of Chemistry, Indiana University, 

 Bloomington, Ind. . I consider it an 

 excellent work for students entering 

 upon the study of chemistry. 



C. F. Adams, Teacher of Science, 

 High School, Detroit, Mich. : I have 

 carried two classes through Wil- 

 liams's Chemistry. The book has 

 surpassed my highest expectations. 

 It gives greater satisfaction with 

 each succeeding class. 



J. W. Simmons, County Superin- 

 tendent of Schools, Owosso, Midi. : 

 The proof of the merits of a text- 

 book, is found in the crucible of the 

 class-room work. There are many 

 chemistries, and good ones ; but, for 

 our use, this leads them all. It is 

 stated in language plain, interesting 

 and not misleading. A logical order 

 is followed, and the mind of the 



student is at work because of the 

 many suggestions offered. We use 

 Williams's work, and the results are 

 all we could wish. There is plenty 

 of chemistry in the work for any of 

 our high schools. 



W. J. Martin, Professor of Chem- 

 istry, Davidson College, N. C. : One 

 of the most admirable little text- 

 books I have ever seen. 



T. H. Norton, Professor of Chem- 

 istry, Cincinnati University, 0. : Its 

 clearness, accuracy, and compact 

 form render it exceptionally well 

 adapted for use in high and prepara- 

 tory schools. I shall warmly recom- 

 mend it for use, whenever the effort 

 is made to provide satisfactory train- 

 ing in accordance with the require- 

 ments for admission to the scientific 

 courses of the University.
