after his arrival at Silverton, he was stricken with typhoid fever, and died upon the 19th of January, in his twenty-ninth year. Always studious and diligent while at the Institute, he went into the world of business with a strong determination to continue his studies and to round out more fully the education he had already acquired. True to this purpose, he purchased the latest and best professional books, and in every way strove to perfect himself. modest and refined tastes, he sought only the best associations; and in the small mining towns to which his work called him he was always a welcomed guest at the best homes and, whenever possible, an ardent worker in the church. Of In his death the class of '93 has parted with a loyal member, one who during his college career was always at the class meetings, and, although never actively connected with the administration of class affairs, was, nevertheless, greatly interested in whatever was before the class for consideration; and his influence was ever exerted for the welfare of the organization. The following spontaneous tribute from one who was well acquainted with him shows very clearly the kind of man he was : "IN MEMORY OF JOHN GOULD ANTHONY "The untimely death of Anthony was a shock and grief to those who knew him well, and it is a pleasure and duty to bear testimony of his genial, manly nature. I knew him in Philadelphia during 1894 and 1895. We were both exiles from home, and my happy acquaintance with him was one of those for which we have so often to thank the dear old Institute. It was at that period in life when dreams of conquering the world of business are rudely dispelled, and the best energies and qualities of men are exerted to the utmost to learn things and gain a foothold. Many good and true men are bitter and sceptical during this period, but it must be recorded of this classmate of ours that never did his courage falter or his sunny nature lose one ray of its faith and helpfulness to others. He was active and useful in his church circle, a constant thinker on subjects concerned with the promotion of good citizenship, and a devoted lover of his Alma Mater. In this latter con nection it should be mentioned that he tried, at one time, to secure space in some of the Philadelphia newspapers for Technology news in order to advertise the Institute. He wrote a long description of his journey West in 1896, which was circulated among his friends. It was unusually complete and interesting, and as such displayed considerable literary merit. "While we stand here, with all courage and willingness to endure the trials and sorrows that are our inheritance, may we not say that he is happy in being spared them, and that our lives have been better by having known this true-hearted gentleman and friend?

During the past fifteen years the employment of water power has received a wonderful impetus from the development of electrical transmission of power and from the rapid introduction of electric lighting wherever power could be cheaply obtained. Almost every New England manufacturing village has a system of lighting, operated from the falls which during the day run its mills; on the larger streams, such as the Merrimack, are extensive plants entirely devoted to the production of electrical energy; while at Niagara are the culminating works, which excite the wonder and admiration of thousands who visit the Exposition. A treatment of the combined works going to make up a waterpower plant has hitherto been lacking, and in taking up the subject Mr. Frizell has performed a useful service to manufacturers and ⚫ engineers. Having received a training in early life in that practical school for hydraulic engineers, the Locks and Canals Company's office at Lowell, to which have been added many years of professional experience, he has become well equipped to discuss the numerous problems that are involved, and to bring to the reader's attention many considerations not often presented in print. Nearly one-half the book is devoted to dams, of which all prominent types and sundry individual examples are described, the high masonry dam being mathematically treated. Works appurtenant to the conducting of water to the turbines canals, racks, headgates, waste weirs, penstocks, etc.—are next considered, and the essential features of good construction pointed out. Turbines of the American type are somewhat fully described, with a partial outline of methods used for speed regulation. Considerable space is devoted to the various modes of power transmission; and the method originated by the author for the direct hydraulic compression of air, now being practically applied on the Quinebaug River, is clearly explained. The closing discussions on the value of reservoir storage and of pondage should be of especial interest to manufacturers; and, in view of the many suits arising over the diversion of streams for public uses, the chapter on the computation of resulting damages has importance for all who may be involved in such controversies. DWIGHT Porter. ELECTRIC LIGHTING BY FRANCIS B. CROCKER. Vol. II.: Distributing Systems and Lamps. pp. vi +, 505. Van Nostrand. Price $3.00. We are accustomed to expect an admirable treatment of any matter to which Professor Crocker lends his pen, and this second volume of his treatise on "Electric Lighting" is in no sense a disappointment. The present work strikes us as a distinct advance over the first volume, both in the matter and the manner of its presentation. The first six chapters are devoted to direct current distribution; and it is pleasant to observe that in the calculations of mains, in the chapter devoted to "Parallel Systems of Electrical Distribution," something more than the mere statement of results is given. There is in much of the matter published for so-called engineers of to-day too great solicitude lest their mental digestion be upset by a mathematical symbol. Then follow five chapters on alternating currents, both single and multi-phase, two chapters on overhead and underground conductors, a chapter each devoted to the arc, arc lamps, interior wiring, incandescent lamps, a brief word on lamps not employing carbon, and a chapter devoted to a description of electric meters. In two appendices are given the "National Electric Code" and the "Report of the Committee on Standardization," an extremely good feature. The book would be improved by something more on compensators, and by a complete index. It is, however, a most useful addition to electrical literature for the student, the engineer, and particularly for the teacher. In a word, it is admirable. H. E. C. INDUCTION COILS AND COIL-MAKING BY H. S. NORRIE. Spon & Chamberlain. illustrations, 5x61⁄2 inches. Cloth, $1.00. pp. xii, 270. 79 If this were only a more expensive book, to which greater space were allotted for review, it would be really worth while to dilate upon its picturesque, entertaining, often amusing style. The statements of scientific fact frequently, like Kipling, leave something to the imagination; and yet for the discriminating reader there is much of genuine value. No one after reading this book needs fail in making an induction coil that will spark. H. E. C. SELF-EXAMINATIONS FOR MEDICAL STUDENTS P. Blakiston's Son & Co. Price 10 cents. Self-examination is good for any one, even for medical students. There seems no valid reason why a person who can answer the 3,500 questions of this little book should fail in at least securing a low pass. Most of them are satisfactorily answered in works published by P. Blakiston's Son & Co. The price of the book brings it within the means even of college professors. H. E. C. SOUNDING THE OCEAN OF AIR BY A. LAWRENCE ROTCH, S.B., A.M. New York and London: Among the bits of Class News published in another column, under the class of '84, is a note in regard to the recent work done by Mr. A. Lawrence Rotch in sounding the atmosphere by means of kites flown from a tug boat. Mr. Rotch has also flown some kites from the end of an ocean steamer on its passage across the Atlantic. He has recently published a book entitled " Sounding the Ocean of Air," which is one of the "Romance of Science " series. This book is founded upon six lectures delivered before YOR |
