376 DISEASE IN WILD MAMMALS AND BIRDS 
ceps of the thigh participating in the protection of the 
belly. Almost any of the intra-abdominal conditions, 
gastroenteritis, mesenteric thrombosis, peritonitis, or 
diseases of the psoas muscle and lumbar vertebra, might 
occasion this attempt at support. Disease of gluteal 
muscles, as hemoglobinuric fever, may produce a palsy of 
the whole pelvic girdle with weakness of the hind legs. 
There may be associated with the weakness of the hind 
legs a humped-up condition of the lumbar spine and 
retraction of the abdomen, sometimes called /'tucked in;" 
in two definite cases of this last sort we have found renal 
pelvic stones and once intestinal sand. Some instances 
are undoubtedly due to meningomyelitis or to poliomye- 
litis and at the place for this subject a few cases will be 
discussed. Meningitis has not been found in the ungu- 
lates showing this weakness. There have been however 
cases of ataxia in the hind legs of deer and antelopes, 
which did not have a ready explanation fitting in with the 
foregoing. Two of these we thought might be due to 
certain grasses in the enclosures and have changed the 
exhibition spaces. No conclusion can be drawn from this 
as yet. No enterocolic disease could be found nor any 
lesion of the sciatic nerve and lumbar enlargement of the 
cord. We have however discovered sciatic neuritis in a 
case like hemoglobinuric fever in a Burchell 's zebra. The 
history of the animal is similar to that of this disease in 
domestic animals in so far as symptomatology is con- 
cerned ; in so far as confinement in a stall is concerned no 
data is at hand but death occurred on December 26th in 
the zebra house whereas he had been accustomed to go 
out into the yard all summer and autumn. 
Meningitis. 
The coverings of the brain and cord have not been the 
seat of the well known acute inflammations seen in 
domestic horses and cattle. Eleven instances of disease 
in the meninges are recorded but, with very few excep-
