The Scientific American: "One will find in this book very good sketches of the lives of the great pioneers in Electricity, with a clear presentation of how it was that these men came to make their fundamental experiments, and how we now reach conclusions in Science that would have been impossible until their work of revealing was done. The biographies are those of Peregrinus, Columbus, Norman and Gilbert, Franklin and some contemporaries, Galvini, Volta, Coulomb, Oersted, Ampére, Ohm, Faraday, Clerk Maxwell, and Kelvin."
The Boston Globe: "The book is of surpassing interest"
The New York Sun: "The researches of Brother Potamian among the pioneers in antiquity and the Middle Ages are perhaps more interesting than Dr. Walsh's admirable summaries of the accomplishment of the heroes of modern science. The book testifies to the excellence of Catholic scholarship."
The Evening Post: "It is a matter of importance that the work and lives of men like Gilbert, Franklin, Galvini, Volta, Ampére and others should be made known to the students of Electricity, and this office has been well fulfilled by the present authors. The book is no mere compilation, but brings out many interesting and obscure facts, especially about the earlier men."
The Philadelphia Record: "It is a glance at the whole field of Electricity by men who are noted for the thoroughness of their research, and it should be made accessible to every reader capable of taking a serious interest in the wonderful phenomena of nature."
Electrical World: "Aside from the intrinsic interest of its matter, the book is delightful to read owing to the graceful literary style common to both authors. One not having the slightest acquaintance with electrical science will find the book of absorbing interest as treating in a human way and with literary art the life work of some of the greatest men of modern times; and, moreover, in the course of his reading he will incidentally obtain a sound knowledge of the main principles upon which almost all present-day electrical development is based. It is a shining example of how science can be popularized without the slightest twisting of facts or distortion of perspective. Electrical readers will find the book also a scholarly treatise on the evolution of electrical science, and a most refreshing change from the 'engineering English' of the typical technical writer."

CATHOLIC SUMMER SCHOOL PRESS SERIES
The highest value attaches to historical research on the lines you so ably indicate, especially at the present time, when the enemies of Holy Church are making renewed efforts to show her antagonism to science and human progress generally. I shall have much pleasure in perusing your work entitled "The Thirteenth Greatest of Centuries."
Wishing you every blessing, I am, Yours sincerely in Xt.,

THE THIRTEENTH GREATEST OF CENTURIES
--By James J. Walsh. M. D., Ph. D., Litt. D.. Dean and Professor of Nervous Diseases and of the History of Medicine at Fordham University School of Medicine; Professor of Physiological Psychology at Cathedral College, New York. Catholic Summer School Press. 110 West 74th Street, N. T., Georgetown University Edition. Over 100 additional illustrations and twenty-six chapters that might have been, nearly 600 pages. Price, $3.50, post free.

Prof. William Osler, of Oxford, delivering the Linacre Lecture before the University of Cambridge, said: "That good son of the Church and of the profession, Dr. James J. Walsh, has recently published a charming book on The Thirteenth as the Greatest of Centuries. He makes a very good case for what is called the First Renaissance."
The Saturday Review (of London): "The volume contains a mass of interesting facts that will start a train of profitable thought in many readers' minds."
The Educational Review said: "The title of Dr. Walsh's book, The Thirteenth Greatest of Centuries, will startle many readers, but we respectfully commend to the open-minded his presentation of that great epoch. A century that witnessed such extraordinary achievements in architecture, in arts and crafts, in education, and in literature and law, as did the Thirteenth, is not to be lightly dismissed or unfavorably compared with periods nearer our own."
The Pittsburg Post said: "Dr. Walsh writes infused with all the learning of the past, enthusiastic in modern research, and sympathetic, in true scholarly style, with investigation in every line. One need only run over a few of the topical headings to feel how plausible the thesis is. The assemblage of the facts and the elucidation of their mutual relations by Dr. Walsh shows the master's skill. The work bristles on every page with facts that may be familiar to many, but which were never before so arranged in just perspective with their convincing force so clearly shown."
Cardinal Moran, of Sydney, Australia: "Just the sort of literature we want for English readers at the present day."
