VIII, B, 3 Crowell and Hammack: Intestinal Parasites 171 



There is a slight fibrous adhesion between the colon and the inferior 

 surface of the liver. Diaphragm stands at the fifth interspace on the 

 left side and the fourth interspace on the right. 



Thorax, — The pericardial sac is large, and contains a few cubic centi- 

 meters of clear fluid. The thymus is long and narrow, measuring 12 by 

 4 centimeters. It is pink, both externally and on section. Thymus weighs 

 30 grams. 



Lungs. — Left lung is bound to the chest wall by a few fibrous adhesions. 

 The bronchi are pink, and contain a little frothy fluid but no mucus. On 

 section the lung is slightly moist, but on pressure very little serous fluid 

 can be expressed. However, the blood vessels are well filled with dark 

 fluid blood. Its surface is smooth, except near the anterior border where 

 there is a fibrous tag. Color of the surface is purplish red. The lung is 

 everywhere soft and crepitant, and pits slightly on pressure. On section 

 the right lung is similar to the left, although the surface is slightly more 

 moist. 



Heart. — On the anterior surface of the right ventricle are 2 slightly 

 thickened, grayish patches. The right ventricle is very prominent, but 

 the left also seems large. The tricuspid ring admits easily four fingers. 

 The auricle is slightly larger than normal. The right ventricle is markedly 

 dilated ; the wall, however, is thin, measuring 3 to 5 millimeters in thickness 

 and the muscle is soft. The tricuspid ring measures 13 centimeters in 

 circumference. The left auricle is normal in size. The left ventricle is 

 fairly well contracted, the chamber being small, and the muscle rather 

 soft and light reddish grayish brown in color. The papillary muscles are 

 rather thick. The wall measures 15 millimeters in thickness. The mitral 

 ring measures 10.5 centimeters. Pulmonary ring measures 7.2 centimeters. 

 Heart weighs 353 grams. 



Spleen is of normal size. On section it is found to be rather firm. 

 The surface is dark red, and the organ contains considerable blood. The 

 Malpighian bodies are barely visible. Spleen weighs 187 grams. 



Kidneys are large. The capsules strip easily, leaving a smooth, pur- 

 plish red surface. On section the cortex is bluish red in color; the glomer- 

 uli are barely visible; striations are regular. The pyramids are purple. 

 The organs are moderately firm. Both kidneys weigh 272 grams. 



Adrenals are thin, and the medullary substance is scanty. 



Pancreas is rather firm. On section it is pink. 



Liver is enlarged. The surface is smooth, and the organ is fairly firm. 

 On section it is uniformly dark red in color and friable, the lobules being 

 easily seen. Liver weighs 1,815 grams. 



Stomach contains a large amount of partially digested food consisting 

 principally of rice. 



Intestines. — There is slight hyperaemia of the upper part of the small 

 intestine, otherwise no lesions are noted. Intestines contain hookworms, 

 ascarides, and trichurides. 



Genitalia are rather small but otherwise normal. 



Urinary bladder is normal. 



Brain. — Meninges are rather moist, especially about the base where 

 they seem slightly thickened. On the surface of the brain in, or in most 

 cases beneath, the pia-arachnoid and embedded in the cortex are found 

 a number of small cysts. These have a slightly thicker capsule, and are 

 in most cases more nearly spherical than those of the muscles. Some
