Science in Short Chapters.

_JOURNAL OF EDUCATION_, Boston:

"'Science in Short Chapters' supplies a growing want among a large class of busy people, who have not time to consult scientific treatises. Written in clear and simple style. Very interesting and instructive."

_ACADEMY_, London, England:

"Mr. Williams has presented these scientific subjects to the popular mind with much clearness and force. It may be read with advantage by those without special scientific training."

_RELIGIOUS TELESCOPE_, Dayton, Ohio:

"It is historic, scientific, and racy. A book of intense practical thought, which one wishes to read carefully and then read again."

_NEW YORK SCHOOL JOURNAL_:

"A volume of handy science, not only interesting as an abstract subject, but valuable for its clear expositions of every-day science. Of Professor Williams as an authority upon such subjects, it is unnecessary to comment. He already has a fame as a scientific writer which needs no recommendation."

_PALL MALL GAZETTE_, London, England:

"Original and of scientific value."

_GRAPHIC_, London:

"Clear, simple, and profitable."

_CANADA BAPTIST_, Toronto:

"A rich book at a marvellously low price. The style is sprightly and simple. Every chapter contains something we all want to know."

_NEWARK DAILY ADVERTISER_, N.J.:

"As an educator this book is worth a year's schooling, and it will go where schools of a high grade cannot penetrate. For such a book twenty-five cents seems a ridiculous sum."

_J.W. BASHFORD_, Auburndale, Mass.:

"A marvellous book, as fascinating as Dickens, to be consulted as an authority along with Britannica, and even fuller of practical hints than the latter's articles. I do not know how you can print its 300 pages for 25 cents."

_AMERICAN_, Philadelphia:

"Mr. Williams' work is a practical compendium."
