Fig. 247. — Mare's mouth, showing tables of incisors and the presence of 



rudimentary tushes. 



In this case, the respective tables of the lower incisors show 

 about the same amount of wear and their " marks " have dis- 

 appeared, probably on account of the tendency to parrot-mouth 

 (Fig. 245). Generally, the lower corner incisors retain their 



marks " at this age.
