where it passed into the eye-ball was richly infiltrated with 
round cells and this was particularly noticeable in the pial- 
septa ; the ciliary nerves at this point were intact, except that 
here and there a round cell could be noticed. The papilla was 
very much swollen and infiltrated with round cells and the 
sheaths of the central vessels participated in this process. The 
retina, especially in the fibre layer and as far forward as the ora 
serrata, was the seat of round cell infiltrations, the infiltration 
showing even to some extent in the ora-serrata. The choroid 
was richly infiltrated, the cells sometimes occurring in little 
groups or heaps, and sometimes being uniformly distributed 
throughout the tissue. The pigment epithelium was loosened. 
The round cell infiltration of the choroid appeared to be less 
pronounced a short distance forward from the equator, but be¬ 
yond this up to the ciliary body and in the latter the cell infil¬ 
tration was abundant. The sclera in general was intact, 
though the walls of the small blood vessels penetrating the 
sclera were infiltrated. 
The vitreous body was somewhat shrivelled and at some 
points was detached from the retina; throughout the vitreous 
body were to be seen numerous cells, partly small, round cells, 
partly large cells, with vacuoles and containing several nuclei. 
The posterior chamber contained coagulated fibrin mixed with 
round cells. The lens was intact except that there was an 
abundant pigment deposit at the anterior capsule and in addi¬ 
tion to this an exudate that soldered the anterior capsule to 
the posterior surface of the lens. The ciliary body was densely 
infiltrated with round cells. The anterior chamber contained a 
fibrinous exudate rich in cells. The iris was infiltrated through¬ 
out with round cells and the cornea showed a slight infiltration at 
the scleral border, as did also the sub-conjunctival tissue at this 
point. The external sheath of the optic nerve of the primarily 
affected eye, all the way up to the chiasm, was only moderately 
affected ; the inner sheath, however, was considerably infiltrated 
with round cells, the infiltration being here and there quite 
dense and at other points more diffuse. The cell infiltration
