the mark on the inside long and irregular. (See plate iv. 
fig. 7.) The other nippers will exhibit considerable indica¬ 
tions of wearing, the tushes be much grown, and the grooves 
on the sides ’will have nearly or quite disappeared, present¬ 
ing an almost regular convex surface. They are still, 
however, as concave within, and with their edges nearly as 
sharp as they were six months previously. The sixth molar 
tooth will have attained its complete height, and the third 
molar will be wanting. This last sign can never be mis¬ 
taken, and if a dealer has removed it, such is the force 
required to displace it, that evident marks of violence 
will remain. The three last grinders and tushes are never 
shed. 
When the animal has attained its sixth year, the mark 
on the central incisors, or nippers, will be completely worn 
off, leaving, however, a little difference of colour in the centre 
of the teeth. The cement which fills the hole produced by 
the dipping in of the enamel will be somewhat browner 
than that of other portions of the tooth, and will exhibit 
evident proofs of the edge being surrounded by enamel. 
This condition has perplexed the inexperienced, as many 
expect to find the surface of the tooth plain, and of a 
uniform colour, whereas they are both irregular and dis¬ 
coloured, as we have above described, (see plate iv. fig. 8.) 
In the second incisors the mark is shorter, broader, and 
more faint, with the enamel of the edges of the corner teeth 
more regular, while the surface gives sufficient evidence of 
wear. The tushes will have attained their full size, being 
fully an inch long, convex outwardly, and a little concave 
inwardly, accuminated towards the point, and slightly in¬ 
curved at the apex. The third grinder will be fully up * and 
all of them presenting a level surface ; so that the mouth is 
now perfect.
