Fig. 66, and the notches in the corner teeth have be- 

 come pronounced. 



At nine years of age, the cups will have disap- 

 peared from the upper center incisors, and will be 

 shallow in the laterals but fairly deep in the corner 

 teeth. The cups do not disappear at such regular 

 intervals in the upper teeth as they do in the lower 

 ones. Therefore, it is not always possible to tell the 

 age of a horse within a year or two, after he has 

 passed his eighth year. However, the character, shape 

 and angle of meet- 

 ing of the incisor 

 teeth may all be 

 used to assist the 

 judgment in de- 

 termining age. As 

 has been formerly 

 stated, horses hav- 

 ing dense, hard 

 bones and hoofs 

 are likely to be 

 rated younger 

 than they are, 

 after eight years of age, when judged by the teeth 

 alone; while horses of softer bony structure are likely 

 to be judged older than they are. 



At ten years, the cups have disappeared from the 

 upper lateral teeth, the notches in the corner upper 

 incisors have become enlarged, and all the signs of 

 advancing age, as described above, are becoming 

 marked.
