Diseases of the chest and the principles of physical diagnosis . only a dull, shortmetallic note closely similar to that heard over the healthy lung (seeFig. 60). Auscultatory Percussion.—This is occasionally of use in outliningorgans. The bell of the stethoscope is placed over, let us say, the is held in position by the patient or an assistant while the examinerpercusses lightly the surrounding regions in a circular direction. We begin at a distance from the heart and percuss toward it in aseries of circles. The tissues, the sound of which is to be compared, mustbe equally distant from the stethoscope, as under normal conditionsthe sound will increase in intensity in approaching the point soon as the organ is reached by the percussion blow the sound willgreatly increase in intensity and we know that its outer boundary hasbeen reached. Instead of percussing some examiners use a vibratingtuning fork, placing the butt of the same against the chest wall in orderto set up intrathoracic vibrations. 92 THE EXAMINATION OF THE LUNGS.
