REPORTS OF CASES. 
many, why cannot this drug be used as well in veterinary prac¬ 
tice. Undoubtedly many of the members of the profession have 
used it with greater or less success, and would it not be well if 
each should give to the rest of the profession the results of his 
observations ? Believing that the best interests of all would be 
thus subserved, I send the following observations. 
A Jersey cow belonging to a dairyman in town, in eating 
about a stack of oat straw got a piece of oat chaff into her eye. 
After numerous fruitless efforts to remove it the owner let it 
go, thinking that in time the eye would “ come all right.” 
But instead of that, the eye became badly inflamed, the 
cornea turning white and opaque, and strong bands of lymph 
being thrown across the piece of chaff, effectually retaining it 
in position. 
The cow, which was a valuable animal, resisted all efforts 
to open the eye by the powerful action of the nictitating mem¬ 
brane and eyelids. 
Four drops of a 4-per-cent solution, introduced one drop at a 
time, three minutes apart, so completely ansesthized the con¬ 
junctiva that with one hand I opened the eye and held the lids 
apart, while with the other I tore the lymph shreds and picked 
out the chaff without having to hold the head otherwise than 
with a halter. 
The pupil was dilated in less than fifteen minutes to near 
its full extent, and the conjunctiva could be raised with the 
forceps with absolutely no “ flinching.” Several times have I 
tried experiments upon my driving horse’s eyes, and find that 
I cannot produce as favorable a condition of the pupil for 
opthalmascopie examination by the use of a 4-per-cent solution 
of atropia sulplms as I can with cocaine. The drug is an expen¬ 
sive one when bought in quantities. The small amount needed 
for ophthalmic surgery renders its use within the means of any¬ 
one; and its perfect action, in so far as my experience goes, ren¬ 
ders its use desirable.
