off in condition. If the tooth be in the upper jaw and the 
roots affected, there will sometimes be a running fiom that 
nostril over the tooth. 
Treatment. — Open the mouth with a speculum, pass the 
hand back and examine the teeth to ascertain which tooth is 
affected. While making the examination it is always best to 
use a twitch as it assists in keeping him quiet. When the 
affected tooth is located remove it with a large molar forceps. 
After pulling keep the tooth, opposite the one pulled, filed 
down so that it will not irritate the gum of the opposite jaw. 
Feed on soft food for a few days until the gum is healed. 
Should the horse be in poor condition give some of the 
following tonic powders to build him up : 
Ground Gentian Root J4 pound. 
Ground Sulphate of Iron 54 pound. 
Mix thoroughly and give a teaspoonful twice a day, in the 
food or on the tongue with a spoon. 
7. Split Teeth. 
The molars or grinders of the upper jaw are more likely 
to split than those of the lower jaw. It does, however, some- 
times occur to those of the lower jaw. The split part of an 
upper tooth generally turns to the outside and cuts the cheek 
while that of a lower tooth generally turns to the inside and 
cuts the tongue. 
Causes. — A split tooth is generally the result of biting 
upon some hard substance — a nail or stone — which is taken 
into the mouth with the food. 
Symptoms. — There is of course great difficulty in eating. 
He is much afraid when an attempt is made to examine the 
mouth, je^ks his head back quickly and shows signs of sore- 
ness about the jaws. Run the hand along the outside of the 
upper jaw. A little pressure opposite the point at which the 
split tooth is situated causes him to jerk his head back 
quickly, an indication of the soreness at this point. When 
eating he fumbles his food about in the mouth but in a few 
minutes throws it only partly chewed. In a short time he 
tries again with the same result. Place a twitch on the nose 
and proceed to examine the mouth by drawing the tongue 
forward and holding the cheek back with the other. Look 
carefully back along the grinders. If the split be found in
