PARROT MOUTH. 



Parrot-mouth is a condition in which the incisors (front teeth) 

 of the upper jaw project further forward than those of the lower 

 jaw, and, when the mouth i,s shut, the upper incisors pass down 

 in f i ont of those in the lower jaw. A horse with this deformity 

 decs not do very well at pasture, for the simple reason that he 

 can not gather sufficient grass to keep him in good condition. 

 But; feeding from the manger, he does very well, except when 

 fed on ear corn, in which case he experiences considerable diffi- 

 culty in getting the grain off the cob. About all that can be 

 dene is to keep both the upper and lower incisor teeth shortened 

 by means of the rasp (Fig. 6), to prevent contact with, and 

 ii-.inry to, the soft tissues. 



UNDERSHOT. 



This is just the opposite from parrot-mouth. It is a deformity 

 in uhich the under jaw is longer than the upper jaw; conse- 

 quently, the front teeth do not meet. The only thing to be done 

 is to cut or rasp off the front teeth when they get too long. 



LAMPAS. 



Lampas, or more commonly called lampers, is the name given 

 to a swelling of the membrane covering the roof of the mouth 

 just behind the front teeth. Animals between the ages of three 

 and five years are most subject to it. On examination of the 

 mouth, the gums and rings of the hard palate, just behind the 

 upper front teeth, are found to be unnaturally reddened and 

 swollen, the animal objecting very much to having the parts 

 pressed upon, showing that the parts are very so're. Many horses
