500 ALPHABETICAL SUMMARY. 
QUITTOR. 
Causes.—Confined pus from suppurating corn; or prick of the sole; 
matter results, and this issues at the coronet. Or from injury to the 
coronet, generating pus, and this burrowing downward, as it cannot 
pierce the coronary substance. The secretion may also penetrate the 
cartilage, and thus establish sinuses in almost every possible direction. 
Symptoms.—The horse is very lame. The animal is easier after the 
quittor has burst. Probe for the sinuses. If, after the superficial sinuses 
are treated, among the creamy pus there should appear a dark speck of 
albuminous fluid, make sure of another sinus, probably working toward 
the central structures of the foot. 
RHEUMATISM. 
Cause.—Generally follows other disorders, as influenza, chest affec- 
tions, and most acute diseases. Very rarely does it appear without a 
forerunner. 
Symptoms.—Swelling of particular parts, generally the limbs; heat 
and acute lameness. The disorder is apt to fly about the body. The 
synovia is always increased when the joints are attacked. The pulse 
and breathing are both disturbed by agony. 
Treatment.—Lead into a loose box; fill the place with steam. (See 
page 313.) Get ready the slings; put the belly-piece under the horse, 
but do not pull it up so as to lift the legs from the ground. Keep the 
steam up for one hour. Then have several men with cloths ready to 
wipe the animal dry; mind they are perfectly silent. Next rub into the 
diseased parts the following : Compound soap liniment, sixteen ounces; 
tincture of cantharides, liquor ammonia, and laudanum, of each two 
ounces. Afterward incase the limbs in flannel. (See page 314.) Then 
give a bolus composed of powdered colchicum, two drachms; iodide of 
potassium, one drachm; simple mass, a sufficiency. Should the attack 
succeed upon other diseases, the diet must be supporting, everything 
being softened by heat and water. Next morning repeat the steaming, 
and give calomel, a scruple; opium, two drachms. At night steam 
again, and repeat the first bolus. Should the horse be fat, withdraw 
all corn, if the strength can do without it. 
RING-BONE. 
Cause.—Dragging heavy loads up steep hills. 
Symptoms.—A roughness of hair on the pastern and a bulging forth
