Muscles atrophic, greenish black over abdomen. Fat absent. Lung is blotched by darker red markings where parenchyma contains distinct excess of frothy pink watery fluid. No fluid or adhesions in pericardium. Heart is contracted, and muscle is pale yellow and firm. The only abnormality consists of slight yellowing of musculature. The abdomen shows great omentum firmly adherent to fundus of bladder. No fluid or other adhesions in abdomen. The liver is normal in size, smooth in surface and has sharp edges, is friable and bright orange yellow. The section surface is glistening, smooth and dry. Organ is poor in blood content, greasy and breaks easily. Bladder is large, contents fluid green bile; duct patulous. Spleen normal. Kidney is small and smooth, diminished in bulk, normal location, smooth surface, and pale yellowish gray, consistency, soft, flabby. Ureters normal. Mouth and teeth normal. Stomach contains scanty brown fluid. Duodenum— Mucosa bile-stained, contained a solitary nematode worm. In its lower portion it becomes filled with a blackish red fluid, and its mucosa becomes studded by heavily outlined punctate hemorrhages whose positions are best seen through serosa. Jejunum similar in condition to duodenum and contains four small nematode worms. At one point, i.e., where the worm is located at beginning of ileum the blood staining of mucosa is strictly in neighborhood of the worm. Capillaries nowhere congested. Ileum contains slight amount of brownish black material, mucosa normal. Large intestine and rectum normal. Pancreas normal. Lymphatics normal. This is a case of death by anemia as result of bites of hookworms. There were certainly more than four worms present antemortem since no males were found, and this may be explained by a possible diarrhœa which has flushed them out. This idea is borne out by empty condition of gastrointestinal tract. Animal Parasites—Uncinaria canina. The four small nematode worms above mentioned conform in all respects to the given anatomical points of uncinaria. All four specimens are perfectly formed females. The location of the hooks was easily determined and established as being in the most dorsal portion of buccal cavity, and as projecting forward and ventrally in two groups of three each in same manner as described heretofore in similar infestations in foxes. The large nematode worm found in duodenum is, from its possession of three lips and its general form, an ascaris. The mustache, however, which is so commonly seen in ascaris worms from this region is absent. Postmortem blood of heart shows red cells granulated and almost worthless for histological study. Nucleated reds, however, are absent but other points valuable in settling the question of anemia cannot be determined.
