developed this diffbrencc will be less observable, 
molar, also contained in its capside and in a state 
wardness, as it will be cut in about 
three months from this date. 
Allusion may here very properly be 
made to Mr. Youatt's account before 
quoted. Pie says that the incisors 
of the sheep " grow with his growth 
until the animal is about fourteen 
or sixteen months old. Then, with 
the same previous process of diminu- 
tion which was described in cattle, 
or carried to a still greater degree, 
the two central teeth are shed and 
attain their full growth when the 
sheep is two years old." 
By way of contrast to this, it 
may be observed that many sheep at 
eic/htcen months old will have cut the 
second pair of permanent incisors. 
Before, however, I proceed to ex- 
emplify this, it is right to quote 
again from Mr. Youatt, as it seems 
that the writings of other persons 
obliged him to qualify the preceding 
statements, and therefore he adds 
that which is perfectly correct : — 
" In examining a flock of sheep there will 
often be very considerable differences in the 
teeth of the hogs or the one-shears ; in some 
measure to be accounted for by a difference 
in the time of lambing, and likewise by the 
general health and vigour of the animal. 
There will also be a material diti'ercnce in 
flocks, attributable to the good or bad keep 
they have had. Those fed on good land, or 
otherwise well kept, will take the start of 
others that have been half starved, and re- 
new their teeth some months sooner than 
those," lie continues — " There are, how- 
ever, exceptions to this ; Mr. Price t sa3 s 
that a llomney JMarsh hog was exhibited at 
the show fair at Ashford weighing fifteen
