they are long, pretty white, and equal.” This is even worse than 
Mr. Parkinson’s four-year-old full mouth, for he acknowledges 
that “ the teeth are not up perfectly until the animal is six years 
old.” The author of the “ Illustrations” is, however, in good 
company, for the amusing but imaginative Buffon has committed 
the same error, and so has the learned editor of the Encyclopaedia 
M etropolitana*. 
I am confirmed, however, in the account which I have given 
of the changes of the teeth, by the high authority of Culley and 
Dickson, who state that the two central teeth appear at two 
years, and that the mouth is full at five. The previous and in¬ 
termediate steps in the process of dentition have not, however, 
been related by these authors, or by any others. 
The grinders will rarely be examined to ascertain the age of 
the beast. They are too difficult to get at, and the same de¬ 
pendence cannot be placed upon them. The calf is generally 
born with two molar teeth, and sometimes with three. The fourth 
appears about the expiration of the eighth month, and the fifth 
at the end of the year, about which time the first molar is shed. 
The second is displaced at the end of the second year, and so 
with the rest, at intervals of a year; but the sixth molar, which 
is from the beginning a permanent tooth, does not appear until 
the sixth year.

A brown mare, three years old, joined the regiment to which 
I have the honour to belong in the month of April 1829, and 
suddenly became, on the 3d of September following, very rest¬ 
less, frequently lying down, rolling, pawing with her fore feet, 
accompanied with a small quick pulse, hurried respiration, to¬ 
gether with great distention of the abdomen. Body costive. .

* I should like to know how the learned commentator on “ Cuvier’s 
Animal Kingdom” would calculate the age of the horse, when he tells us 
(vol. iv, p. 435) that “ There are eight incisors in each jaw.”
