DISEASES OF BLOOD AND BONE MARROW 91 
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 neighbor- 
hood 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 diarrhoea 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 uneinaria. All four specimens are perfectly formed females. The loca- 
tion 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 here- 
tofore 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 ques- 
tion of anemia cannot be determined. 
Lung. — There are no abnormalities in supporting tissue. Alveolar 
walls are markedly congested. Bronchi normal and show no trace of 
larval hookworm infestation. Air sacs contain many red blood cells 
together with a few heart-failure-cells. Congestion of lung. 
Liver. — No excess of fibrous tissue. Finer details of stracture can- 
not be made out owing to advanced autolytic changes. The only possible 
pathological changes consist of localized areas where liver cells have 
fused to form notable masses of pink granular material suggesting 
local necroses. Autolysis. 
Intestines. — Four sections are present and all show essentially the 
same character of changes. Interstitial tissue between muscular tissue 
and submucosa loosely aiTanged as though separated by edema. 
On luminal side of muscular mucosa is a distinct zone of striking 
tawny yellow color with hematoxylon-eosin combination. This zone is
