"Mr. Hood's style is pleasant, clear, and flowing, and he sets forth and holds his own opinion well." _EPISCOPAL RECORDER_, Philadelphia: "An admirable and able Life of Oliver Cromwell, of which we can unhesitatingly speak words of praise." _NEW YORK TELEGRAM_: "Full of the kind of information with which even the well-read like to refresh themselves." _INDIANAPOLIS SENTINEL_, Ind.: "The book is one of deep interest. The style is good, the analysis searching, and will add much to the author's fame as an able biographer." _THE WORKMAN_, Pittsburgh, Pa.: "This book tells the story of Cromwell's life in a captivating way. It reads like a romance. The paper and printing are very attractive." _NEW YORK HERALD_: "The book is one of deep interest. The style is good, the analysis searching." II. 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." III. The American Humorist. _COMMERCIAL GAZETTE_, Cincinnati, Ohio: "It is finely critical and appreciative; exceedingly crisp and unusually entertaining from first to last." _CHRISTIAN INTELLIGENCER_, New York: "A book of pleasant reading, with enough sparkle in it to cure any one of the blues." _CONGREGATIONALIST_, Boston:
