AGE OF THE HORSE. 



75 



Page 74 shows the two inside views of the lower jaw together, 

 so that the pupil can see the contrast between the old and young 

 mouth. 



We will also put the two outside views together on this page, 

 so the pupil can see the width and shape of the teeth and gums. 

 By noticing closely, it will be seen that the gums in the young 

 mouth are nearly straight across, while the old mouth shows the 

 gums extending up between the teeth. 



The upper view on page 74 shows twenty-four years old ; the 

 lower view, only five. On page 75 the upper view shows five, and 

 the lower one twenty-four years.
