The presence of six broad teeth in the front of the mouth 
is shown in the next illustration (Fig. 40). 
These teeth may be looked for in many sheep which are 
entered as not exceeding two years old, and no objection can 
be made on this ground, although the third pair of incisors are 
not, under ordinary circumstances, present before two years and 
three months. 
Some difficulty may arise in the mind of an inspector who 
finds these different appearances in sheep which are in adjoining 
pens, or even in the same pen. But in such circumstances no 
hesitation need be felt in accepting the evidence of the molars, 
and disregarding that of the incisors.
