The cardiac orifice is opposite the seventh left costal cartilage about 2.5 cm. 

 from the side of the sternum; it corresponds to the level of the tenth thoracic verte- 

 bra. The pyloric orifice is on the transpyloric line about 1 cm. to the right of the 

 middle line, or alternately 5 cm. below the seventh right sternocostal articulation; 

 it is at the level of the first lumbar vertebra. A curved line, convex downward and 

 to the left, joining these points indicates the lesser curvature. In the left lateral 

 line the fundus of the stomach reaches as 'high as the fifth interspace or the sixth

costal cartilage, a little below the apex of the heart. To indicate the greater cur- 

 vature a curved line is drawn from the cardiac orifice to the summit of the fundus, 

 thence downward and to the left, finally turning medialward to the pyloric orifice, 

 but passing, on its way, through the intersection of the left lateral with the trans- 

 pyloric line. The portion of the stomach which is in contact with the abdominal 

 wall can be represented roughly by a triangular area the base of which is formed by 

 a line drawn from the tip of the tenth left costal cartilage to the tip of the ninth
