tliat inverts the fiiid Cavity, is partly the Occafion of that 

 exquilite Pain which is felt in the Tooth ach. Thefe V^ef- 

 fels before- mention'd, namely, the Vein, Artery, and 

 Nerve, are inclofed in one common Capjda, or Sheath, 

 when they enter the Jaw, and running alonp a proper 

 Channel under the Roots of the Teeth, lend off to each of 

 them, in their Pallage, thofe fmall Twigs aforefaid. 



7'hough the Teeth of Horfes are differently fituated from 

 thofe in Men, and are alfo more numerous, yet as to their 

 Offices, they admit of the fame Divilion, and are of three 

 Kinds 5 namely, the Inclfoiei^ Canmi^ and Molar es. 

 a-, r -r The Incifores^ Cutters or Shredders, aie 



thofe we call the Foreteeth, being ieated in 

 the Fore part of the Jaw. They are broad and fharp-cdg- 

 ed, the better to crop and bite off the Grafs : They are in 

 Number twelve, fix on each Jaw. Thefe haye but one 

 Root or Fang. 

 cri Q • • The next are the Canim^ or Dog-teeth, 



which in Horfes are called the Tu/J^cs ; and 

 are of Ufe to break whatever is too hard for the Fore- teeth 

 lo cut or fhear afunder. Thele have alfo but one P'a^g, 

 and are feldom to be found in Mares. 

 tj., y, , Thofe of the third Rank are the double 



Teeth, and are named Alolares or Grinders, 

 becaufe they grind the Food like a Milftone : They are in 

 Number twenty-four, twelve on each Jaw ; their Seat is 

 in the inner Part of the Mouth, being invironed on theip 

 Outfide by the Cheeks, to prevent the Food falling out of 

 the Mouth while it is grinding. Thefe have feveral Af- 

 perities on thtir upper Part, by which Means they are ren- 

 der'd more fit for their peculiar Ufe.

 the Jpe of a Horfe may be known to be under feven Years 

 old, having till then feveral thin Shells, or 

 Scalesgrowingroundtheoutfideof the Top of them, forming 

 a hollow in the Middle. And it is to be cbfcrved, that the 

 nearer a Horfe comes to that Age, the more thofe Edges are 

 Xvorn down, till at lafl they become even with the reft ; fo 

 that the Age of a Horfe is no more to be known by that Sign. 

 The feveral Periods of a Horfe's Age, while only a Colt, 

 are alfo diftinguifliable by the Fore- teeth ; but thefe Things 

 being fufriciently known by every one who has been ufed 

 among Horfes, I fhall therefore proceed to the Bone of the 

 7'on|iue. That
