CANINES. 



The canine teeth are frequently referred to as being rep- 

 resented in youth by temporary predecessors. This claim 

 cannot be accepted as entirely correct. The needle-like ca- 

 nines, occasionally observed in three-year-old colts, must be 

 regarded as a freak of perverted dental evolution rather 

 than as a part of the normal economy. 



THE OX. 



Central Incisors* — Erupt at birth, become prominent at 

 one month and shed at one and a half years of age. 



Lateral Incisors — Erupt at birth, gain the level of the 

 arcade at one month and shed at two and a half years. 



*Lower jaw only.
