Excerpt from Physical Diagnosis of Diseases of the Chest This book is intended for students and, so far as I am aware, contains nothing original. I have written it because I have not been able to find any small work upon the subject which does not contain glaring errors. The correct books are too large; the small books are out of date and repeat such well-worn myths as that the aortic second sound is normally louder than the pulmonic second, that aortic regurgitant murmurs are usually best heard in the sec ond right interspace, that a hypertrophied left auricle can produce dulness and pulsation near the left sternal border, that systolic re traction at the cardiac apex means adherent pericardium, that epi gastric pulsation denotes hypertrophy of the right ventricle, etc. Further, none of the smaller text-books contains any adequate ao count of muscle sounds, of pulrnonary atelectasis, or of adherent pericardium. To record the well-known but often forgotten truth on such matters as these has seemed to me of importance in small books as well as in encyclopaedic treatises. The diagrams illustrating respiratory types are modifications of those used by Wylie and Sahli. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
