lateral incisors the wear is confined to a small portion of the 
anterior edge which is nearest to the central teeth. These 
appearances are indicated in the drawing (Fig. 4). 
Between two and six months old the central and lateral incisors 
increase in size with the growth of the animal. At six months 
old the mouth has a very neat and compact appearance. The 
centrals and laterals are well developed, and tlieir anterior 
edges are worn level. The posterior edges are, however, still 
rather below the anterior, and the table, therefore, is not perfectly 
formed. The next drawing (Fig. 5) was taken from the mouth 
of a cart-colt at the age of si.\ months.
