_The New York Medical Journal_: "We welcome works of this kind; they are evidence of the growth of culture within the medical profession, which betokens that the time has come when our teachers have the leisure to look backward to what has been accomplished." _Science_: "The sketches are extremely entertaining and useful. Perhaps the most striking thing is that everyone of the men described was of the Catholic faith, and the dominant idea is that great scientific work is not incompatible with devout adherence to the tenets of the Catholic religion." THE POPES AND SCIENCE--The story Of the Papal Relations to Science from the Middle Ages down to the Nineteenth Century. By James J. Walsh, M. D., Ph. D., LL.D. 440 pp. Price, $2.00 net. PROF. PAGEL, Professor of History at the University of Berlin: "This book represents the most serious contribution to the history of medicine that has ever come out of America." SIR CLIFFORD ALLBUTT, Regius Professor of Physic at the University of Cambridge (England): "The book as a whole is a fair as well as a scholarly argument." _The Evening Post_ (New York) says: "However strong the reader's prejudice...he cannot lay down Prof. Walsh's volume without at least conceding that the author has driven his pen hard and deep into the 'academic superstition' about Papal Opposition to science." In a previous issue it had said: "We venture to prophesy that all who swear by Dr. Andrew D. White's History of the Warfare of Science With Theology in Christendom will find their hands full, if they attempt to answer Dr. James J. Walsh's The Popes and Science." _The Literary Digest_ said: "The book is well worth reading for its extensive learning and the vigor of its style." _The Southern Messenger_ says: "Books like this make it clear that it is ignorance alone that makes people, even supposedly educated people, still cling to the old calumnies." _The Nation_ (New York) says: "The learned Fordham Physician has at command an enormous mass of facts, and he orders them with logic, force and literary ease. Prof. Walsh convicts his opponents of hasty generalizing if not anti-clerical zeal." _The Pittsburg Post_ says: "With the fair attitude of mind and influenced only by the student's desire to procure knowledge, this book becomes at once something to fascinate. On every page authoritative facts confute the stereotyped statement of the purely theological publications." PROF. WELCH, of Johns Hopkins, quoting Martial, said: "It is pleasant indeed to drink at the living fountain-heads of knowledge after previously having had only the stagnant pools of second-hand authority."
