9. Those teachers in particular who have little time to prepare experiments for pupils, or whose experience in the laboratory has been limited, will find the simplicity of treatment and of experimentation well worth their careful consideration.

Those who try the book find its merits have not been overstated.

A. B. Aubert, Prof. of Chemistry, Maine State College, Orono, Me.: All the salient points are well explained, the theories are treated of with great simplicity; it seems as if every student might thoroughly understand the science of chemistry when taught from such a work.

H. T. Fuller, Pres. of Polytechnic Institute, Worcester, Mass.: It is clear, concise, and suggests the most important and most significant experiments for illustration of general principles.

Alfred S. Roe, Prin. of High School, Worcester, Mass.: I am very much pleased with it. I think it the most practical book for actual work that I have seen.

Frank M. Gilley, Science Teacher, High School, Chelsea, Mass.: I have examined the proof-sheets in connection with my class work, and after comparison with a large number of text-books, feel convinced that it is superior to any yet published.

G. S. Fellows, Teacher of Chemistry, High School, Washington, D.C.: The author’s method seems to us the ideal one. Not only are the theoretical parts rendered clear by experiments performed by the student himself, but there is a happy blending of theoretical and applied chemistry as commendable as it is unusual.

J. I. D. Hines, Prof. of Chemistry, Cumberland University, Lebanon, Tenn.: I am very much pleased with it, and think it will give the student an admirable introduction to the science of chemistry.

Horace Phillips, Prin. of High School, Elkhart, Ind.: My class has now used it three months. It proves the most satisfactory text-book in this branch that I have ever used. The cost of apparatus and material is very small.

O. S. Wescott, Prin. North Division H. Sch., Chicago: My chemistry professor says it is the most satisfactory thing he has seen, and hopes we may be able to have it in future.
