IMPEDIMENT IN THE LACHRYMAL DUCE. 61 
ward, to avoid injuring the eyeball, and a separate needle be employed 
for each divided surface. The thread being brought through, cut off the 
needles, and loop, but do not tie the thread. Proceed with another 
suture, and do not tie that; then with another, observing the same 
directions, and thus, till the eyelid has a sufficient number of sutures. 
Then proceed to draw all to an even tightness—none should be abso- 
lutely tight. The parts ought only to be approximated, not tied firmly 
together; well, all the sutures being of equal size, they are fastened, and 
the operation is concluded. 
But as the wound begins to heal it is apt to itch, and the horse will 
often rub the eye violently to ease the irritation. To prevent this, 
fasten the animal to the pillar-reins of its stall, and let it remain there 
till the wound has healed; the injury will in a short time close, but the 
sutures should be watched. When the holes begin to enlarge, the thread 
can be snipped. If the punctures be dry, let the divided sutures remain 
till nature shall remove them. If they are moist, and the wound ap- 
pears united, you may try each thread with a pair of forceps; should 
any appear loose, then withdraw it, for after division it can be of no 
use, and may provoke irritation; however, should it be retained, employ 
no force; have patience, and it will come forth without man’s inter- 
ference. 
Feed liberally, regulate the bowels 
by mashes and green meat; smear the 
wound with oil of tar to dispel the flies ; 
for should the accident happen during the 
warmer months, these pests biting and 
blowing upon so delicate a part as the eye 
may occasion more harm than our best 
efforts can rectify. When the lid is bitten |. ee EN ce pee

IMPEDIMENT IN THE LACHRYMAL DUCT. 
The lachrymal duct in the horse is a small canal leading from the eye 
to the nostril; it commences by two very minute openings near the 
terminations of the upper and lower lids, at the inner corner of the 
eye; it emerges upon the dark skin which lines the commencement of 
the horse’s nostril, being on the inner side of the internal membrane.
