AGE OF ANIMALS. 



To fold the age of a horse. 



The colt is born with 12 grinders. When 4 front teeth 

 have made their appearance the colt is 12 days old, and 

 when the next 4 appear it is four weeks old. When the 

 corner teeth appear it is eight months old, and when the 

 latter have attained the height of the front teeth it is a year 

 old. The two year old colt has the kernel (the dark sub- 

 stance in the middle of the tooth's crown) ground or worn 

 out of all the front teeth. In the third year the middle 

 front teeth are being shifted, and when three years old these 

 are substituted for the horse teeth. In the fourth year the 

 next 4 are shifted, and in the fifth year the corner teeth are 

 shifted. In the sixth year the kernel is worn out of the middle 

 front teeth, and the bridle teeth have now attained their full 

 growth. At seven years a hook has been formed on the 

 corner teeth of the upper jaw : the kernel of the teeth next 

 at the middle is worn out, and the bridle teeth begin to wear 

 off. At eight years of age the kernel is worn out of all the 

 lower front teeth, and begins to decrease in the 'middle up- 

 per fronts. In the ninth year the kernel has wholly disap- 

 peared from the upper middle front teeth, the hook on the 

 corner teeth has increased in size, and the bridle teeth loose
