THE STREPTOTHRICOSES 583 
opaque, architecture probably normal. The gall-bladder is distended 
with viscid green bile; the common duct is patulous. The spleen has 
a rough, thin capsule, consistency tough and resilient, the section sur- 
face is mottled red with purple points; on section two small, pale objects 
seem to be squeezed out. The kidney capsule is smooth, strips easily 
leaving a smooth, deep red surface, the consistency is soft, 
the cortex is deep red, then a purple line between it and the red 
medulla, striae invisible. The stomach contains frothy gi-ayish mush. 
The mucosa is finely mammillated, deep pink until the last third when 
it becomes deep red, deeply injected and somewhat thickened. The 
pylorus is closed. Externally the gut is congested, in places translu- 
cent but for most part seems thickened by reddish swelling of both 
external layers and mucosa. The mucosa is granular or pebbly with 
here and there a small bloody suffusion. The histological section of 
lung shows alveoli open, septa relatively thin but somewhat congested, 
bronchi mostly open and connective tissue not increased. Some few 
bronchi, especially the larger, show a slight catarrhal bronchitis but 
mostly an infiltrative peribronchitis. The nearby veins and arteries 
show the most striking change, there being in nearly all of them a 
distinct thrombosis without circumferential pneumonia. In one place a 
distinct peribronchial pneumonitis was found. The kidney shows very 
marked congestion of all parts, causing compression, cloudiness and 
granularity of the epithelium. Glomeruli and connective tissue about 
normal. The intestinal serosa is "negative save for congestion. Sub- 
mucosa is densely infiltrated with mononuclears, some in definite groups. 
Section does not show areas mentioned in notes but these could be accu- 
mulations of cells with congestion. No streptothrix forms. Section 
fi'om the infectious focus of face consists of active granulation tissue, 
densely injected and filled with mononuclears of two types, one the 
lymphoid cell, the other of the young connective tissue type. Areas of 
grouping like abscesses are seen and some necroses, Streptothrix in 
small numbers in the cellular collections. 
Nail tailed Wallaby {Macropus unguifer). Kangaroo disease of 
nasal region. Necrotizing bronchopneumonia (Aspergillus fumigatus 
and Micrococcus albus). Acute diffuse splenitis. Congestion of liver 
and kidney. The general condition of coat and nutrition is good. The 
face is wide just below the eyes. About the " hare lip " and the nose 
the soft tissues are soft, gray, necrotic. All the internal nasal tissues 
seem swollen, gray-red. There is subcutaneous edema, bloody in places, 
around the right face, eye and jugular angle. Tissues of nasopharynx 
swollen, deeply injected and covered by a thick mucus. Pharyngeal and 
buccal cavities negative. Tonsillar areas pink and flat. Larynx and 
trachea slightly swollen but pale on mucosa. Salivary glands and cervi- 
cal glands normal in size and pale pink. Pleurae pale and empty. Lungs 
swollen out uniformly, quite cottony except at lower right base where 
there is a nodule about 3x5 em. firm and doughy. On section it is 
found to be a peribronchial consolidation of pale reddish gray color
