EIGHTH ANNUAL REPORT. 123 
fibers in the anterio-lateral and the anterior ground bundle; a few 
scattering degenerated fibers are also present in the posterior 
tracts, but these columns are in general free from degenerations. 
The blood vessels in the gray matter are quite extensively con- 
gested and areas of myelitic degeneration are frequent. 
Lumbar and Sacral Cord.—The degenerations present are al- 
most exclusively limited to the descending columns. 
Posterior Root Ganglia.—No alterations are evident above the 
level of myelitis. Ganglia corresponding to the area of softening 
show a few small patches of cellular exudation and a shrinkage 
of some of the ganglion cells. 
Blood Vessels——The blood vessels throughout the spinal cord, 
with the exception of the area of sonienine g, show no apparent 
changes. 
The case is clearly one of transverse myelitis of the mid-dorsal 
cord with the descending degenerations below the lesion and the 
usual ascending degeneration above. Aside from this the cord 
seems to have been normal and the cause of the myelitis is not 
apparent. 
CASE III. 
Vervet Monkey (Cercopithecus lalandu).—The animal pre- 
sented the general clinical manifestations of cage paralysis. Six 
weeks elapsed between the time of the first observation of the dis- 
ease and the death of the animal. During this period the monkey 
emaciated moderately and progressive erouuy of the rear extrem- 
ities have become marked. 
The autopsy, which was performed by Dr. Blair, showed mod- 
erate general emaciation with marked atrophy of the hind ex- 
tremities from the pelvis down. There was a large deep indolent 
appearing ulceration of the tissues over each tuberosity of the 
ischium. The heart was in diastole and normal. The Jungs were 
normal. The liver was congested. The kidneys were moderately 
congested. The bladder was well filled with urine and was other- 
wise normal. The stomach, pancreas and intestines were normal 
throughout. Brain and Spinal Cord.—Gross examination shows 
no lesions in either brain or cord. 
MICROSCOPIC EXAMINATION. 
Cervical Cord.—Microscopically, the spinal cord in the cervical 
region shows a considerable number of degenerated fibers in the 
direct and crossed pyramidal tracts and in the antero-lateral tracts.
