THE MOUTH PALATE. 



ners or angles of the lips are sometimes wounded by the ti^^ii- 

 ness of the bearing-rein, or by sharp or badly formed bits. If 

 inflammation or ulcers in the mouth follow contusions inflicted 

 by the bit, a little cooling medicine may be administered ; and 

 to the ulcers themselves, tincture of myrrh, diluted with water, 

 or alum dissolved in water, may be applied with advantage. 



THE BONES OF THE MOUTH. 



The bones, in and giving form to the mouth, are the superior 

 maxillary or upper jaw (b, Fig. 1, and /, Fig. 2,) containing the 

 grinders : the anterior maxillaiy, or lower part of the upper jaw, 

 (b, Fig. 1, n, Fig. 2, r, Fig. 3,) containing the upper-nippers or 

 cutting-teeth ; the palatine bone (below 8, Fig. 3,) and the pos- 

 terior maxillary or under jaw (a, Fig. 1, and 2U, Fig. 3,) con- 

 taining all the under-teeth. 



The size of these, their connection with the other bones of the 

 head, aiid their muscular attachments, will be sufiiciently learned 

 from a careful inspection of the cuts, Figs. 1, 2, 3, and 12. 



THE PALATE. 



Adhering to a portion of the three bones just described, and 

 constituting the lining of the roof of the mouth, is the palate {t, 

 Fig. 3,) composed of an elastic and dense substance, divided into 

 several ridges called bars. The following cut gives a view of 

 them.
