[In an addendum in a future number of the ARCHIVES,results concerning the method applied to other organs willbe given.]. Fig. 3. In marking out the anterior surface of the heart, the pec-toral extremities of the binaural wooden stethoscope wereplaced over the fourth and fifth intercostal spaces close tothe left of the sternum, and percussion was made from theperiphery to the praecordia by the auscultator, with closedeyes, by means of the percussion hammer, or indexand middle finger of the right hand, indifferently. Assoon as a change in the pitch and intensity of thepercussion note was observed, the pitch becominghigher and the intensity increased, the spot where thischange occurred was marked, and a sharpened knitting-needle, ten inches long, was thrust in at that point. This A USCUL TA TOR Y PERCUSSION. 277 was done in each intercostal space of the praecordia to theright and left of the sternum, and in the right mammary lineat points which were supposed to correspond to the upperand lower borders of the liver, and also in the mid-sternalline at the point supposed to indicate the lower border ofthe liv
