that inveds the faid Cavity, is partly the Occafion of that 

 exquilite Pain which is felt in theTooth-ach. Thei'e Vef^ 

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

 Nerve, are inclofed in one common Capjula^ or Sheath, 

 "when they enter the Jaw, and running along a proper 

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

 them, in their Pafiage, thofe Imall Tv/.gs aforesaid. 



Though 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 Divifion, and are of three 

 Kinds J namely, the Incifores^ Canini^ and Jfolares. 

 fj-, T- Y -es ^^^ Irici fores ^ Cutters or Shredders, are 



thofe we call the Foreteeth, being feated in 

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

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

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

 Root or Fang. 

 a-j^ P . . The next are the Canini^ or Dog-teeth, 



which in Horfes are called the Tujhes ; and 

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

 to cut or fhear afunder. Thefe have alfo but one Fa^g, 

 and are feldom to be found in Mares. 

 cTi yi \ Thofe of the third Rank are the double 



7'eeth, and are named Molarcs or Grinders, 

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

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

 jn the inner Part of the Mouth, being invironed on their 

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

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

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

 der'd more fit for their peculiar Ufe. 

 cri r 1 7- ? The two foremoft of thefe Teeth, which 

 HcK/e IS ^kno^K-n ^^"^ "^^^^ ^^^ Tuflies, are thole by which a 

 th^ Jpe of a Horfe may be known to be under feven Years 



old, having till then feveral thin Shells, or 

 Scales growing round the outlide of the Top of them, forming 

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

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

 worn down, till at laft 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 diltinguilliable by the Fore- teeth ; but thefe Things 

 being fufhciently known by every one who has been ufed 

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

 Toi]8;ue. That
