TEXTBOOK ADVERTIs.e.m.e.nTS THAT APPEARED IN THE ORIGINAL EDITION
INTRODUCTION TO CHEMICAL SCIENCE
By R.P. WILLIAMS, Instructor in Chemistry in the English High School, Boston. l2mo. Cloth. 216 pages. By mail, 90 cents; for introduction, 80 cents.
This work is strictly, but easily, inductive. The pupil is stimulated by query and suggestion to observe important phenomena, and to draw correct conclusions. The experiments are ill.u.s.trative, the apparatus is simple and easily made. The nomenclature, symbols, and writing of equations are made prominent features. In descriptive and theoretical chemistry, the arrangement of subjects is believed to be especially superior in that it presents, not a mere aggregation of facts, but the science of chemistry. Brevity aud concentration, induction, clearness, accuracy, and a legitimate regard for interest, are leading characteristics. The treatment 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 cla.s.ses so large that the simplest and most practical plan has been a necessity.
Thomas C. Van Nuys, Professor of Chemistry, Indiana University, Bloomington, Ind.:
