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. Right lobe measures 7.5 x 4.5 x 2 cm.; left lobe, 6.5 x 5 x 2 
em. 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 
em., 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; 
trabecule 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. 
Kidneys—Measure 6.5 x 1.7 x1 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, 4. ¢.,
