part is between the Bon-peritoneal posterior surface of the liver and the abdominal 

 wall Tim. of course, like the two preceding areas, has no peritoneum. _ The rest 

 lies in contact with tin- lower surface of the liver, and is coated by the peritoneum of 

 tin- posterior abdominal wall. The antcnor surface of the .left capsule is nearly or 

 quite pentoneal, resting against the stomach, the spleen, and the tail of the pancreas. 

 Structure. The suprarenal body is invested by a thin, but fairly strong, 

 fibrous capsule. Section across the thicker parts of the organ displays an outer zone, 

 or cortc i . '5-1 20 mm. in thickness ,, which surrounds the central medulla. Where 

 thin- .wards the borders, the medulla is reduced to a narrow zone and maybe 



entirely wanting when- Lest developed, as in the middle of the organ, it may attain 

 a thickness ot over 5 mm. The cortex is usually of a dirty yellow color, presenting
