and are form'd with other Branches in feveral Pkxus'Sy as 

 thofe laft dclcribed, but not lb numerous. They take iheir 

 Courfe chiefly to the Alefentery and Loins, ending towards 

 the Fundament in leveral fmall Twigs. 



Having defcribed the Nerves which take ^^^ STerves

 Neckj Back, and Loins, which fhall, in a 

 Manner, be but ju ft named; they being in Number thlrty- 

 fevcn, whereof leven arife from t'le Neck, feventeen from 

 the Back, and thirteen from the Loins and Oi Sicrtim. 



Thole of the Neck are all of them difperfed, partly on 

 the Mufcles of the Face, partly on the Mulcles of the Neck 

 itfelf, and partly on thofe of the Shoulders and Fore-legs; 

 only it is to be remarked, that a Twig from each Nerve 

 of the fifth Pair, being joined with the like Twigs of the 

 fourth and fixth, compofe that remarkable Nerve, which 

 goes to the Midriff, called the Nervus phrcnicui. 



The firft two Pair, which arife from between the Ver- 

 teln<e of the Back, communicate with the lowermoft of the 

 Neck, fending forth feme Twigs to the Neck and Shoul- 

 ders : The lecond, as alfo all that follow, fend each of them 

 a Twig 10 the IntercoHal Nerve, or Nerve of the ninth 

 Pair, their other Branches being chiefly fpent on the Jnter-

 Slips towards thofe of the lower Belly. 



As theie are chiefly difperfed among the Mufcles of the 

 Back, and the Intercoftal, and the Mufcles of the low'et 

 Belly, fo thofe of the Loins, and thofe alfo which fpring 

 from the Oi Sacrum., are difperfed into the Mufcles of the 

 Loins, Hips, and hinder Legs, only that the anterior^ or fore- 

 branches of the firft Pair of the Loins, are fpent on the fleftiy 

 Part of the Midriff, and the Mufcie Pjoai^-3,vA ihtpo/ierior 

 Branches on the Mufcie called the Longijjimus Dorfi. 



The Yard of a Horfe, and the Womb of a Mare, are 

 alfo furnilhed from the anterior Branches of the Loins, and 

 the Stones from the anterior Branches of the Os Sacrum^ 

 fent off to them from the fore-part of the Thigh.
