The molars (grinders) are somewhat square, looking at 

 the table surface: while the temporary or milk molars 

 are only twelve in number, there are twenty-four perma-

 of the upper jaw. The surfaces of these molars do not 

 form two horizontal surfaces, but two sloping ones, the 

 outer edge of the upper molars coming lower down than 

 the inner edge of the same teeth, whereas the lower row 

 of molars have the inner edge higher, this fact has to be 

 remembered in the operation of dressing (floating) the 

 teeth. The formula below gives the number and arrange- 

 ment of the teeth in the adult of the different animals:

 very apt to tear it, and cause soreness of the udder, with 

 a consequent disinclination of the sow to let the pigs 

 suckle her. 



Telling the Age. Foals at birth have four incisors, the 

 middle ones, -and twelve molars; at six months four lat-
