tis. Spleen and Lymph Nedes.—Both are much congested and 
are extensively tubercular. Stomach—Empty except for a small 
amount of yellowish fluid, no food is present. Jntestine and Gen- 
ito-Urinary Tract—Negative. Brain and Spinal Cord.—Gross 
examination of the spinal cord after it has been hardened, showed 
meningitis, most intense at lower levels. 
MICROSCOPIC EXAMINATION. 
Cervical Cord.—In the upper cervical levels the pia-arachnoid 
shows a moderate degree of chronic thickening of the membranes, 
and in places the connective tissue cells of its structure show ev1- 
dences of recent proliferation, particularly about the vessels, which 
are quite universally injected. In the lower cervical regions the 
membrane shows in addition a very marked serous exudate, which 
in places contains a good many leucocytes, chiefly mononuclear 
cells, but in places there are a good many polynuclear ones. The 
cellular exudate is most apparent about the blood vessels, which 
are mostly congested. 
The substance of the cord shows a very general dilatation 
of the lymph channels, particularly of the perivascular spaces, 
and in some places the lacune in which the cells are lodged are 
also dilated, this without apparent shrinkage of the ganglion 
cells. 
The vessels of the cord are injected and a few of them show 
a slight exudate of small round cells into the adventitia. 
Sections compared after the Marchiit method show occasional 
degenerated fibers, chiefly in the posterior tracts and most numer- 
ous in the column of Goll. Occasional degenerated fibers are also 
found in the descending tracts, but nothing like a systematic de- 
generation is evident in them. 
Sections stained with the Neisl blue, show a very general dis- 
integration of the chromatic plaques of the ganglion cells, some 
of them are still evident but show lack of staining affinity, others 
show a finely granular disintegration of the plaques. These evi- 
dences of degeneration are very general and in some places amount 
to actual cytoclasis; it is more than probable that many of the 
alterations are of post-mortem origin. 
Dorsal Segments.—Series of sections taken in the upper, mid 
and lower dorsal segments show alterations very like those de- 
scribed in the cervical region, except that the lesions increase in 
intensity as the lower levels are reached and, though altogether 
similar to those described in the cervical regions, are of much
