shaped aneurism which measures 11 to 12 centimeters in the long diameter 

 and 7 to 8 centimeters in the short diameter. The walls are firm and 

 retain their shape. They measure 3 to 4 millimeters in thickness. The 

 intimal surface of the aneurism is roughened in numerous places with 

 flat, soft yellowish plaques which average 0.5 to 1 centimeter in diameter 

 and about 2 millimeters in thickness. 



The upper extremity of the aneurism lies immediately below Poupart's 

 ligament, while the lower extremity lies at the opening of Hunter's canal. 

 Both the iliac artery leading into the aneurism and the continuation of the 

 femoral artery from the aneurism are apparently normal. 



An operative wound had been made over Poupart's ligament, and the 

 iliac artery had been ligated just above the aneurism. 



On section of the body there is found a very small amount of subcuta- 

 neous fatty tissue. The muscle is a pale reddish brown and is somewhat 

 soft in consistence. 



Abdomen. — The serosa of the small intestine has a light grayish color, 

 that of the large intestine is rather pale, and the entire serosa is moist. 

 The abdominal cavity itself is moist, but does not contain any free fluid. 

 The diaphragm is located at the fifth rib on the right and the sixth on the 

 left side. The abdominal viscera lie in normal relationship to each other. 



Thorax. — The thymus is atrophied. 



Pleural sacs. — Both pleural sacs are obliterated with fibrous adhesions 

 over the apex and somewhat posteriorly, while anteriorly they are free 

 from adhesions. The parietal pleura has a grayish color, while the visceral 

 pleura shows a blackish color over most of its surface. 



Lungs. — The lungs themselves are very large. The entire upper lobes of 

 both lungs are consolidated and hard in consistence. On section the upper 

 lobes cut with very much resistance, showing a surface which is smooth, 

 very compact, and black, but in some places there are elevated whitish 

 areas of 1 to 2 millimeters in diameter, the entire cut surface having the 

 appearance as though cutting through a lump of coal. The lower lobes 

 of both lungs are voluminous and float high in water, although the upper 

 portion of the lower lobe of the right lung shows a condition similar to 

 the upper lobes of both lungs. Section through the lower lobes shows a 

 rather smooth surface of normal compactness which is greenish black and 

 moist. The bronchi have a reddish color and contain mucoid material. 



Heart. — The parietal pericardium is pale, smooth, and thin. The peri- 

 cardial sac is about normal in size and shape and is free from adhesions; 

 it contains a normal amount of fluid. The epicardium is rather pale and 

 covers some fat; in the other places it is smooth and thin. The heart 

 itself is somewhat enlarged, the tricuspid valve admitting almost four 

 fingers, the mitral valve barely three. The left auricle is considerably 

 distended with blood, and the right auricle is also distended with blood, 

 while the right ventricle and left ventricle both appear to be enlarged, and 

 the walls are slightly thicker than normal. The muscle is pale brown and 

 is very soft and rather flabby; the cut surface is smooth and dull. The 

 endocardium covering the aortic and mitral valves is somewhat thickened, 

 while throughout the remaining portion of the heart it is pale, smooth, and 

 thin. The blood is coagulated, forming coagulvmi of chicken-fat consistence. 



Aorta. — The aorta extending from the aortic valve up to and involving 

 the transverse arch is considerably dilated and at one place shows an out- 

 pouching over a circular area of 6 to 7 centimeters. This outpouching is as
