NATURAL SCIENCE. 



accordance with the requirements for 

 admission to the scientific courses of 

 the University. 



C. F. Adams, Teacher of Science, 

 High School, Detroit, Mich. : I have 

 carried two classes through Wil- 

 liam's Chemistry, and the book has 

 surpassed my highest expectations. 

 It gives greater satisfaction with 

 each succeeding class. 



C. K. Wells, formerly Supt. of 

 Schools, Marietta, 0. : The book 

 bears acquaintance the best of any 

 book of like character that I have 

 ever examined. 



W. T. Mather, Teacher of Science, 

 Williston Seminary, Fasthampton, 

 Mass. : I have used the book in the 

 laboratory very successfully. I can 

 heartily commend it for the method 

 used and the clear and concise treat- 

 ment of the subject. 



J. W. Simmons, Supt. Schools, 

 Owosso, Mich. : 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. There is enough and 

 not too much in the work. 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. Our high 

 schools have no province in chemistry 

 beyond the basic facts. Too many 

 text-books go beyond this introduc- 

 tory field, but not far enough to clear 

 away the mists that arise. The stu- 

 dent's mind is lumbered with things 

 of which he sees no application. It 

 is not education but the barest kind 

 of stuffing. 



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. The 

 above opinion is based upon an ex- 

 perience of twelve years as teacher 

 of chemical science. 



Laboratory Manual of General Chemistry. 



By R. P. WILLIAMS, Instructor in Chemistry, English High School, Bos- 

 ton, and author of Introduction to Chemical Science. 12mo. Boards, 

 xvi + 200 pages. By mail, 30 cents ; for introduction, 25 cents. 



rpHE book contains one hundred experiments in general chemistry 

 and qualitative analysis, blanks opposite each for pupils to 

 take notes, laboratory rules, complete tables of symbols, with 

 chemical and common names, reagents, solutions, chemicals, and 

 apparatus, and the plan of a model laboratory. Minute directions, 

 and suggestions designed to help the pupils observe and draw 

 inferences, characterize each experiment. 



W. M. Stine, Prof, of Chemistry, 

 Ohio University, Athens, 0. : It is a 

 work that has my heartiest endorse- 

 ment. I consider it thoroughly peda- 



gogical in its principles, and Its use 

 must certainly give the student the 

 greatest benefit from his chemical 

 drill.
