burnt in with an acid that is capable of destroying the hardest substances 

 But this falsification may be detected, 1st, by comparing the upper with the 

 lower jaw which they omit "to lile;" 2d, by noticing whether the marked 

 teeth have the riog before described, as pertaining to the sucking teeth, but doe« 

 not belong to the horse teeth — lastly, these latter are larger, of a brownish yellow 

 txnge, and soon acquire tartar, very unlike thefine whitenessof the sucking teeth. 



On rising three 3'^ears old, the two fore teetb 

 (below, and two above) fall out, and are re 

 placed by two horse teeth, having the hollow 

 mark in the middle, as shown in the annexea 

 cut. As just said, they are also larger and of 

 darker colour than the sucking teeth. But 

 between the third and fourth years, two fur- 

 ther colt's teeth (as well above as below) shed, 

 and are replaced by "horse teeth," i. e. larger 

 and browner than the sucking teeth, with the 

 black mark ; the tushes also push forth, and 

 the horse is now fully mouthed, as re- 

 presented by the cut in the margin. 



Only the corners now reinain un- 

 changed from colts' to horses' teeth. 

 These differ from the others in being 

 shorter, smaller, and of a shell-like ap- 

 pearance, until the middle of the fifth 

 year, when these also are displaced by 

 horse teeth, in shape much like the 

 former, and their marks but just per- 

 ceptible within the upper surface. But, 

 toward the completion of five years of 

 age, they become larger, are more 

 strongly marked, and are grooved on the 

 inside, which groove denotes the age to 

 be five with precision ; no deception can 

 be practised on this point, nor as regards 

 the tushes, which are now curved, hav- 

 ing grooves inside, that may be felt with 

 the finger, and seen as represented in the 

 figure annexed. At this age the two 

 front teeth give proof of teing worn, 

 principally on the outer edge • the wear- 

 ing away goes on, and at six years the 

 surliice is level, or as they say, "the mark, 

 is gone," whilst the next two teeth also 

 begin to wear. Now, also, the grooves 

 just spoken of in the corner teeth fill up ; 

 the curve in the tushes is diminished, 1. 

 at seven years their grooves fill up in like 

 manner, and become convex in another 

 year or two. Up to this age only the two 

 corner teeth retain the mark, and that 

 but slightly ; when the horse acquires 

 the term "ajTcd,"and these two likewise 

 soon after become smooth.
