No one can read this book without compensation, without becoming more thoughtful concerning the phenomena of creation; and he need lose none of his reverence for the supremacy of the Divine Law.—_Rural New Yorker._ We could say much in commendation of Prof. Phin’s little book. An intelligent reader can hardly fail to be interested in it, and many might be benefited.—_Country Gentleman._ The book can not fail to interest even those who do not fully accept the theory it advocates.—_Boston Journal of Chemistry._ It is a new scientific view of the matter.—_Phrenological Journal._ The book, although not large, will prove exceedingly interesting to all who have ever directed attention to this matter, and contains more solid and suggestive thought than many voluminous treatises on the subject.—_Insurance Monitor._ The work is ingenious and original, and presents many striking suggestions.—_American Baptist._ We believe Prof. Phin has started upon the correct basis, and his theory is mainly tenable. His views are presented in a manner which, though terse, is easily comprehended.—_Daily Guardian_ (Paterson, N.

Price 50 Cents per year.= It is characteristic of young Americans that they want to be DOING something. They are not content with merely _knowing_ how things are done, or even with _seeing_ them done; they want to do them themselves. In other words, they want to experiment. Hence the wonderful demand that has sprung up for small tool chests, turning lathes, scroll saws, wood carving tools, telegraphs, model steam engines, microscopes and all kinds of apparatus. In nine cases out of ten, however, the young workman finds it difficult to learn how to use his tools or apparatus after he has got them. It is true that we have a large number of very excellent text-books, but these are not just the thing. What is wanted is a living teacher. Where a living teacher cannot be found, the next best thing is a live journal, and this we propose to furnish. And in attempting this, it is not our intention to confine ourselves to mere practical directions. In these days of knowledge and scientific culture, the “Why” becomes as necessary as the “How.” The object of the YOUNG SCIENTIST is to give clear and easily followed directions for performing chemical, mechanical and other operations, as well as simple and accurate explanations of the principles involved in the various mechanical and chemical processes which we shall undertake to describe. The scope and character of the journal will be better understood from an inspection of a few numbers, or from the list of contents found on a subsequent page, than from any labored description. There are, however, three features to which we would call special attention:
