On the Teeth of the Ox, Sheep, and Pig, 
tions, which do not affect the interests of our Agricultural shows 
to the same extent as the instances of early teething, the denti- 
tion of the sheep is completed a year before it is said so to be by 
our authors. Mr, Youatt writes, as we have seen, "that at four 
years old the sheep has six teeth fully grown, and at j^ye years old 
all the teeth are perfectly developed." 
In conclusion, it should be stated that the foregoing account 
of the teething of the sheep is the result of long investigation 
of the subject, and has not been arrived at from prize animals 
exclusively. These sheep fortunately have furnished correct 
dates of age as well as facts of dentition, while other animals 
of all breeds, and under all circumstances of keep, have furnished 
facts with an approximation only to age. 
To assist the inquirer into this subject I close the dentition 
of the sheep by inserting the two tables to which reference has 
been so frequently made in the course of this exposition.

I now proceed to the teething of the animal of which I have 
lastly to speak, namely, the Pig. 
DENTITION OF THE PIG. 
The importance of a knowledge of the teething of Pigs is but 
little, if any, less than of the Ox or Sheep. Perhaps we should 
not be far wrong in stating, that in several respects it is even of 
greater moment the agricultural public should be well informed 
respecting the evidences which the teeth of the pig afford in 
determining the age of the animal : for the paucity of precise 
information upon the dentition of the pig, has doubtless hitherto 
led to many of these animals ])eing exhibited at Agricultural 
shov/s, whose correct age, if known, would justly have led to their 
disqualification, and from the same cause it has also happened.
