is chloride of sodium—teaspoonful to a pint of water; it 
supplies a collyrium nearest in value to the natural secretions 
of the eye. 
If possible, I always advise an animal to be taken from 
work, and placed in a well ventilated stall, darkened in 
front and fed moderate rations of oats and hay, or if in season 
green meat. Corn is to be avoided. If exercise seems to be 
necessary have it done after sunset, or on cloudy days. Ex¬ 
cessive work, and both trotting and running should be limited. 
The collyria used with the greatest advantage and success 
are: Atropia solution, four grains to an ounce of distilled 
water ; cocaine five per cent, solution of the hydro chlorate ; 
astringent collyrium.

The most convenient method of applying collyria to the 
eye is by the Barnes Eye Dropper, or by a bit of absorbent 
cotton on the end of a match or toothpick. 
Especially in simple or complicated ophthalmia, bandages, 
ice bags, nitrate of silver, sulphate of copper, local phlebot¬ 
omy from the lachrymal vein are to be avoided, as they are 
too irritating and too severe in inexperienced hands. Also 
the application of urine, and infusion of tea leaves; these only 
complicate matters. 
The use of the ophthalmoscope is useful in making a 
diagnosis, also in ascertaining the condition of the lens alter 
the operation has been performed, and the eye cleaned up. 
The normal reflex seems to be restored, although spots or 
specks are sometimes discerned on the anterior face of the 
lens, which, if another attack does not take place, apparently 
remains in status quo , and, as far as I have observed, rarely 
interfere with sight, except when large; then they may 
make the animal shy, especially at reflected light from dif¬ 
ferent objects.
