THE EYE 407 
coniea, much wrinkling of the iris and opacity of the 
depths. After the fourth attack in this eye it was com- 
pletely blind. Material was obtained from this eye during 
its last attack, but it was merely serous fluid containing 
a few blood cells and epithelium, but no bacteria. 
**In transferring the affection from this animal, the 
conjuctival sac was washed with 1-5000 bichloride of 
mercury solution and well rinsed with salt solution. The 
anterior chamber was then entered with an aspirating 
needle and the exudate removed. This consisted of 0.4 cc. 
slightly turbid straw colored fluid containing a few 
shreds of lymph. Bacteriological cultures, moist and dry 
preparations were made from a part of this, while the 
remainder was introduced into the anterior chamber of 
the second horse. This animal's eye showed the effects 
of the traumatism for eight days, and then was normal 
save for a small opaque spot in the cornea left from 
needle puncture. After twenty-three days a small patch 
of lymph collected in the pupil. Tliis increased slowly 
accompanied by lacrymation until the twenty- seventh 
day, when a sudden and violent conjunctivitis arose. The 
lymph in the anterior chamber likewise suddenly 
increased and rapidly became pus, forming a hypopyon. 
The conjunctivitis became purulent. The violent stage 
lasted five days and slowly subsided, leaving an ectropion 
wdth a densely injected bulbar conjunctiva, almost com- 
plete corneal opacity and an irregular contraction of iris, 
apparently due to several small synechiae. The depths 
could not be seen because of the corneal condition. This 
stage of affairs remained during the rest of the animal's 
life, two months. He was permitted to live to see if an 
exacerbation of this chronic process or involvement of 
the other eye would appear. Such not occurring in two 
months, he was killed and the eyes removed. Fluid 
removed from the left eye of the first horse when killed 
during the last attack was injected into the anterior 
chamber of a third horse. This animal's eye received
