DESCRIPTION OF PLATE XI.

Drawing represents a section from the dorsal region of the same cord (B-), but showing a more advanced change in myelitis.

a. Thickened vessel, hyaline layer.

BB. Thickened connective tissue; the nuclei multiplied, grouped in twos and threes.

Y y. Nerve-tubules invaded (atrophied ?).

There were also fibroid appearances in this section, but to what degree the changes were old we could not determine, because much of the tissue was evidently swelled and obscured by recent exudation.
