pendulous skin. Treat the wound with the lotion of chloride of zinc— 
one grain to the ounce of water—and it will heal after some weeks. 
CAPPED KNEE. 
Cause.—The same as the previous affection. 
Symptom.—A soft tumor in front of the knee. 
Treatment.—If let alone, it would burst and leave a permanent blem- 
ish. Draw the skin to one side, and with a lancet pierce the lower sur- 
face of the tumor. Treat the wound as an open joint. 
CATARACT. 
Cause.—Looking at white walls, or receiving external injuries. Spe- 
cific ophthalmia generates a permanent cataract. 
Symptoms.—When partial, shying; if total, white pupil and blind- 
ness. 
Treatment.—Color the inside of the stable green, as cataract, when 
not total, is sometimes absorbed. 
CHOKING. 
Causes.—Something impacted in the gullet, either high up or low 
down. 
Symptoms—High Choke.—Raised head; saliva; discharge from the 
nostrils; inflamed eyes; haggard countenance; audible breathing; the 
muscles of neck tetanic; the flanks heave; the fore feet paw and stamp; 
the hind legs crouch and dance; perspiration; agony excessive. Low 
Choke.— The animal ceases to feed; water returns by the nostrils; 
countenance expresses anguish; saliva and nasal discharge; labored by 
seldom, noisy breathing; roached back; tucked-up flanks, while the 
horse stands as though it were desirous of elevating the quarters. 
Treatment.—Make haste when high choke is present. Perform tra- 
cheotomy to relieve the breathing; insert the balling-iron, or, with a hook 
extemporized out of any wire, endeavor to remove the substance from 
the throat. If the choking body is too firmly lodged to be thus re- 
moved, sulphuric ether must be inhaled to relax the spasm. The ether 
not succeeding, an egg is probably impacted. Destroy its integrity with 
a darning-needle carefully inserted through the skin; then break the 
shell by outward pressure. Low choke is seldom fatal before the expi- 
ration of three days. Give a quarter of a pint of oil every hour; in 
the intermediate half hours give sulphuric ether, two ounces; laudanum,
