It is a great pleasure to publish this book in celebration of the 88th birthday on March 3, 1971, of Dr. Yasu Kuno, a member of the Japan Academy and Emeritus Professor of Nagoya University. This celebrated scholar, who is not only respected by those under his direction but who is also a great credit to the medical science of Japan, is a pioneer in the field of physiological research on human perspiration. The result of his life's work "The Physiology of Human Perspiration" (Churchill, London, 1934), to which he devoted all his energies, must be called a monumental work. This book has won worldwide recognition as one of the most authoritative references in this field. Following this work, in 1956, Dr. Kuno published a supplementary volume which contains many of the results of his later research, "Human Perspiration" (Charles C Thomas, Springfield, Illinois). The beginning of his research in perspiration goes back to 1922, when Dr. Kuno was a professor of physiology at Manchuria Medical College. This was also the start in Japan of systematic studies of physiology centering on the study of the regulation of body temperature. Since then, while a professor of physiology at Manchuria Medical College, Kyoto University, Nagoya University and the Mie Prefectural Medical Col lege, and even after cessation of his duties there, Dr.
