j6 The Anatomy of a HORSE. Chap. V. 



The fccond is called Peronaus AnticuSy tho' improperly 

 in a Horfe, who wants that Bone which in Man is named 

 Perone^ or Fibula. This takes its Origin from the upper 

 Appendix of the Tibia or Leg-bone, and is inferted into the 

 Outfide of the Inftep-bone, which with the reft of the Foot 

 it moves forward and fomewhat outward. 



The Foot is alfo extended or drawn back- 



^'"dbtllT"' """^^^^^ ^"^ ^^^'■^^ Mufcles, the firft is called 

 ae y }ree Ga/Irccfiemius ExternuSy and is that Muf- 

 " cle which in Man forms the Calve of the 



Leg. It takes its Rife from the inner Head of the Thigh- 

 bone, and Part of it from the outer Head of the fame 

 Borie, and afterwards uniting together about the middle of 

 the Leg, they there turn into one ftrong Tendon, which bein^ 

 united with that of the following Mufcle, to wit, the GaJ- 

 trocnemius iiiternus^ are both inferted into the Heel-bone. 



This Mufcle lieth ibmewhat under the former, arifmg 

 from the hinder part of the upper End of the Leg-bone, 

 and is inferted as aforefaid. 



The laft Extender of the Foot is called Plantaris^ or 

 the Mufcle of the Soal or Tread ; it arifes flefhy, round, 

 and flender, between the former two, taking its Origin 

 from the back part of the lower Head of the Thigh-bone, 

 and in its Defcent foon becomes a flender round Tendon ; 

 "which, joining very clofely with the Tendons of the for- 

 mer two, palles down to the Heel bone, where it leaves 

 tliem, and proceeds along the back part of the Inltcp-bone, 

 and the two Pafterns, terminating within the Foot all over 

 the Bottom of it, making that part of the Foot which lies 

 next under the Soal, and plainly appears when the Soal is 

 drawn out. The Tendons of thefe three Mufcles joining 

 together, form that great Sinew called Magna Chorda, by 

 which the Butchers hang up their Meat. 



The Foot is alfo moved fomewhat fide-

■^ ■' two Mufcles. 



The firft is called Tibialis PcfiicuSy having its Origin 

 from the upper End of the Leg- bone, and its ufe being 

 to move the Foot obliquely inward. 



The fecond, called Peronaus Pofiicus, arifes from the 

 upper and hinder part of the Leg-bone, by a nervous and 

 flrong Beginning, and defcending with the Tendon of the 

 Peronaus Anticus, on the outfide of the Hock, continuing 

 its Courfe beyond it to the Bottom of the Foot, into which
