§. IV. Of the Larynx, 6«i Pharynx, with tie Tonfils, &6. 



Tho' thefe do not properly belong to theCheft, yet as I 

 have already treated of the Gullet and Windpipe, to which 

 the Larynx and Pharynx are united ; and as the one has 

 Communication with the lower Venter, and the other with 

 the Cheft, I have therefore chofe to take Notice of them 

 under this Divifion, leaving thofe Parts by which they are 

 circumfcribed, to be confidered with the Bones and Mulcles. 



The Larynx is compofed of five Cartila- ^, , 

 ges or Griftles; the firft of which is call'd ' ^rynx. 

 Scutiformis, becaufe it refembleth a Shield : The next is 

 call'd Annularis, from its likenefs to the Ring which the 

 Turks wear when they go a Ihooting: The third and 

 fourth, becaufe they are joined together under one common 

 Tegument, and refemble an Ewer, are therefore termed 

 Cnttales ; thefe two form the Glottis or little Tongue : 

 The fifth is named the Epiglottis, becaufe it is placed 

 above the Glottis. The Subftance of this is foft, and ia 

 fhape like an Ivy-leaf, and ferves as Valves to hinder any 

 Ihing from falling into the Windpipe. 



Thefe Cartilages are mov'd by feveral j^^ yr^ 

 Pair of Mufcles, and ferve principally to 

 frame and modulate the Voice in all Creatures, and are 

 iherefore the Inftruments of neighing in Horfes. 



The Larynx has two Pair of Glands or Kernels belong- 

 ing to it ; one Pair is placed on its upper Part, and at the 

 Sides of the Uvula, and are called the Ton- cr^ Tonfils 

 Jils ; and by fome, in human Bodies, the 

 Almonds of the Ears. Thefe feparate a great deal of 

 the Slaver which comes from a Horfe's Mouth, and ferVe 

 to moiften not only the Larynx, to which they chiefly 

 belong, but alfo the Gullet, by which means every thing 

 pafles down it the more eafily. 



The other Pair are plac'd at the lower End of the 

 Larynx, one on each Side of the Scutifortn, or Shield-like 

 Kjriftlej thefe in Horfes are very hrge, and are fwell'd 

 when a Horfe has the Glanders. 



The Top of the Gullet, or Pharynv:, The Pharynx, 

 which is fo call'd from its Office, becaufe it 

 carries and conveys Food from the Mouth towards the 

 Stomach ; is fomewhat more flefhy than the reft of the 

 G«Uet, being alfo feated in the upper Part of the Throat
