them against the posterior peritoneal wall. It is fastened to the 

 parietal peritoneum, laterally, and at the pubis. The lower margins of 

 the right and left lobes of the liver extend down between the sternum 

 and omentum to within 3 cm. of the tip of the xiphoid. 



Liver (Fig. 4). The first organ which presents itself on removing 

 the sternum. Eight lobe measures 7.5 x 4.5 x 2 cm. ; left lobe, 6.5 x 5 x 2 

 cm. Total weight 50 gm. or 2.8 per cent of body weight. Uni- 

 formly reddish brown with smooth and glistening surface, soft and 

 friable. Lobule about pin-head in size, center darker than periphery ; 

 usually distinct, at times difficult to see. The cut surface shows small 

 blood-vessels on cross and longitudinal section. The lobulation is less 

 readily seen. 



Spleen (Fig. 6). Lies just behind the liver. Measures 2 x 1.5 x 1 

 cm., weighs 1 gm., or .05 per cent of body weight. It is small, soft, 

 reddish brown. Beneath its smooth and glistening capsule, may be 

 seen bluish white Malpighian bodies, slightly larger than pin-points, at 

 times indistinct. On section, the capsule appears very delicate; 

 trabeculse are few, but usually definite, containing gaping blood-vessels. 

 Malpighian bodies at times are prominent. Pulp does not rise above 

 edge of capsule. 



Heart. Lies within a delicate, transparent pericardium, containing 

 a small amount of clear serum. Myocardium is uniformly reddish 

 brown. 



Lungs. Bright red and of a characteristic construction, consisting 

 of a mass of entwined air tubules with large lumina and spongy walls, 

 separated from each other by a small amount of vascular connective 

 tissue. On section, this construction becomes more pronounced. The 

 wall of each air tubule projects as a pale ridge, separated from its 

 neighbor by a red linear depression, in which blood-vessels are common. 



Gastro-intestinal Tract, Pancreas and Adrenals. These are of little 

 interest except that beneath the serosa of the lower half of the intestine 

 are frequently seen pearly nodules, less than a pin-head in size. 



Mesentery. A delicate, cobweb-like membrane with some fat, but 

 no demonstrable lymph-glands. 



Sidneys. Measure 6.5 x 1.7 x 1 cm., and weigh together 12 gm., or 

 7 per cent of body weight. They are uniformly reddish brown with a 

 slightly nodular surface. 



Bone-marrow. Taken from long bones of upper and middle third 

 of leg. It is very soft, semifluid, bright red, mottled with yellow, i. e. }
