92 DISEASE IN WILD MAMMALS AND BIRDS 
smooth homogeneous and contains a few spindle and stellate cells 
with no capillaries and with little or no fibrillation. It abuts 
upon the fundi of the crypts. Interstitial tissue of mucosa is loose 
and infiltrated with round and spindle cells in its deeper portions. 
Here it is also congested but congestion is most marked toward lumen 
where masses of free blood cells occur in interstitial tissue, within 
lumina of crypts and within lumen of intestine itself; no parasites or 
ova are found. Epithelium of crypts has granular cytoplasm; goblet 
cell formation frequently seen; cilia well preserved. Edema; Subacute 
catarrhal enteritis Hemorrhage. 
Six instances of nephritis, four parenchymatous and 
two diffuse, are recorded in the total of seventeen cases 
of secondary anemia in carnivores. Except in the skeletal 
disease the marrow is very mildly affected, some edema 
and reddening grossly and moderate hyperplasia 
minutely, being the only noteworthy changes. 
The next order is that of the Ungulata wherein we 
have found but two cases of frank anemia, an Isabelline 
Gazelle {Gazella Isabella) and an Aoudad {Ovis tragela- 
phus). The former had several lesions of different 
etiology and nature so that an impoverishment of the 
blood is not astonishing: parasitic (?) cyst in lung, 
chronic infective arthritis, calcareous tuberculosis, 
congestion and edema of lungs, osteomalacia, and 
osteofibroma of maxilla. The condition of the auodad 
was too indefinite to permit conclusions. 
The marsupials are represented by two common 
Opossums {Didelphys virginiana) and a Rufous Rat 
Kangaroo {Aepypryynmis rufescens), two of which suf- 
fered also from rickets. The condition of the bone 
marrow was unfortunately not recorded, but in other 
rachitic marsupials this tissue follows the changes seen in 
other orders. One opossum had a hypertrophic gastritis 
mth numerous Physaloptera turgida, a worm frequently 
associated with chronic thickening of the mucosa; there 
was also an early portal hepatic cirrhosis with enlarge- 
ment of the spleen.
