death is usually rapid, as in the solitary case coming under my 
notice; here there was a well-marked congestion of the men¬ 
inges with a large quantity of serum in the pia-mater, producing 
a great deal of pressure, which was probably the immediate cause 
of death; the arachnoidal spaces were filled with transudate, but 
no microscopical evidence of lesion in the substance of the brain 
proper. The congestion and transudation is as easily explained 
in this case as in the lesions of other parts of the body, being 
entirely due to stagnation of the blood current, a prominent 
feature of the disease. < 
Other rare complications of this disease are lesions which 
occur in the eye, all of which are evidently due to impaired 
circulation. The first manifestation in this organ is seen m the 
sub-conjunctival connective tissue, which becomes infiltrated 
with serum of a yellow color, intermixed with a greenish tinge, 
indicating a disturbance of the liver; sometimes a sudden trans¬ 
udation of serum, or coagulable lymph, takes place into the 
anterior chamber of the eye, producing an absolute blindness, 
which will continue for 15 or 18 days, but reabsorption is not 
complete until 30 or 35 days. Should the lesion be more 
forcibly concentrated on this organ, then, as above described, 
there will occur a veritable haemorrhage into it, due to the rup¬ 
ture of a capillary in the ciliary plexus. These conditions 
occur principally in the convalescing period, after all external 
manifestation of the disease has passed away, and perhaps after 
the patient has been discharged as cured. My experience with 
these complications is limited to one example of plastic iritis in 
an animal owned by one of our most prominent physicians, Dr. 
E. L. Dunn, and one example of haemorrhagic iritis in an animal 
owned by a wealthy sugar refiner. In each case one of our 
noted specialists, Prof. Earlan, was in consultation, and appeared 
to be extremely interested. These cases made a good recovery 
in from 28 to 30 days. M. Decroix has described a case of 
instantaneous and complete amaurosis, a lesion quite as easily 
explained as either of the others, as being due to an infiltration,., 
or haemorrhage, into the retina.
