The "March of Medicine" is a compilation of six lectures for the laity offered by the New York Academy of Medicine in 1941. The papers were written by Abraham Meyerson, Perrin H. Long, Paul Reznikoff, Thomas M. Rivers, Richard H. Hutchings and Chevalier Jackson. In a concise, clear and interesting style these men have given the historical background, the present advances and the possibilities for the future in the fields of mental inheritance, chemotherapy, hematology, study of the viruses, care of the mentally ill and, finally, bronchoscopy. Although written for the laity, this book should be interesting to those members of the medical profession who enjoy reading about the historical development of modern scientific medicine. The volume is most readable and should be a valuable source of information for the layman.
