pac*, andks Veilels fo fmall and clofely laid together, as can- 

 not but render them ealily obftmcted. But yet in the Cafe 

 we have nientioned, when a Horfe has a lingring Difeafe' 

 upon him, the Swelling does not readily increafe, becaufe 

 the Matter is but llowly derived towards it ; and likewife a« 

 the PafTages of the Gland are more than ordinarily inlarg'd^ 

 therefore a Quantity of Matter is difcharg'd proportionablof 

 to the Supplies it receives ; and tha Smallnefs and Gom- 

 padnefs of the Vefiels, and their Difpofition into an infinite' 

 Number of Circumvolutions and Turnings, is alfo the Caufs 

 why the Swelling does not eafily decreafe. 



Thofe Swellings of the glandulous Parts that turn to Im- 

 poflumation and Matter, are many of them of the encyfied 

 Kind ; and that is alfa owing to the Stru<fture and Make of 

 the Kernels, moft, if not all of them, having little Qy/x, or 

 Receptacles for their proper Juices, which may be eafily 

 lill'd and enlarg'd, when their excretory Du<5ts are wholly 

 or in a great meafure ihut up, as muft undoubtedly happen 

 in all fuch Cafes. 



^e Matter ex^ ^"^ ^^ comt in the fecond place, to take a 

 amind. " V^^W" of thofe Swellings, with rfegard to the 



Matter whereof they are form'd \ and here 

 it will b^ necelTary to confider, that the Matter becomes va- 

 rious, according to the various Difpofition of Horfes, or ac- 

 cording as the Tumours are varioully difpofed and feated j 

 for when they happen to be fuperficial and outward, the 

 Matter is then, for the moft part, dry, which depends, irt 

 a great meafure upon their Proximity and Nearnefs to the- 

 Skin, whereby the thinner Parts are the more eafily evapo- 

 rated, and caft off thro* the Pores; tho' in other moift Con- 

 ftitutions, the Matter will fometimes be humid and moift^ 

 The Matter deriv'd from Membranes and Sinews is general- 

 ly thin and vifcid, and that which comes from Bones is oily 

 and ftinking; but the Matter which is more immediately de- 

 rived from Blood, if a Horfe be in good Cafe, is of a middle 

 Nature, neither too thick nor too thin, neither is it too wate- 

 ry nor too vifcid. And thus it feems to be very plain and 

 evident, as all Matter is form'd of Blood, or the Juices pro- 

 duced of Blood, the Matter, in all Tumours, will therefore 

 participate chiefly of thofe Juices from whence it is immedi- 

 ately derived. 



The next thing to be regarded in the Matter, is its Co- 

 lour, and this alfo depends upon the Difpofition of the 

 Biood. If the Blood abounds with Choler or Gall, the 

 Matter will be yellow s and it will be more or lefs fo, ac- 



cording
