The Stomach, especially when distended with gas, aflfords its own resonance to percussion of the lower part of the left side of the thorax as high, it may be, as the fourth rib, in the lateral region. Article II.—The Cardiac Region. The extent of cardiac percussion dulness will differ according to the force used in percussion, whether slight or great. Gentle percussion de- tects dulness only where the heart is uncovered by lung ; this is the area of superficial dulness. Stronger percussion detects the dulness of the heart where it lies behind the lung ; this is the area of deep dulness : and it only is indicative of the size of the heart. i. The Superficial area is roughly triangular in shape, the right side of the triangle being the midsternal line from the level of the fourth chondrosternal articulation downwards, the hy- poteause being a line drawn from the same articulation to a point immediately above the apex-beat, the base being a line drawn from immediately below the apex-beat to the point of meeting between the upper limit of liver dulness
