MOUTH AT 7 YEARS. 





Fig, 252. — 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. 250, p. 797). Generally, the lower corner incisors retain 

 their " marks " at this age.
