pa6l, and iis Vcllels fo rmull and clofely Inid together, ascan- 

 not but rc.'ider them eaiily obftructed. But yet in the Cafe 

 we have mentioned, when a Horfc has a hngring Difeaie 

 upon him, the Swelling does not readily increafe, becaufe 

 the Matter is but flowly derived towards it ; and hkewife as 

 the Paflagesof the Gland are more than ordinarily inlarg'd, 

 therefore a Qiumtity of Matter is difcharg'd proportionable 

 to the Supplies it receives ; and ths Smallnefs and Com- 

 padlnefs of the V'cilels, and their Difpofition into an infinite 

 Number of Circumvolutions and Turnings, is alfo the Caufe 

 why the Swelling does not enlily decreate. 



Thofe Swellings of the glandulous Parts that turn to Im- 

 poftumation and M.itter, are many of them of the encyjhi 

 Kind ; and that is alio owing to the Structure and Make of 

 the Kernels, moft, if not all of them, having little Cyjh^ or 

 Receptacles for their proper Juices, which may be eafily 

 fill'd and enhrg'd, when their excretory Dudts are wholly 

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

 in all fuch Cafes. 



(jn -M ,, . ^"t ^^'^ come in the fecond place, to takea 



amind View of thofe Swellings, with regard to the 



Matter whereof they are form'd ; and here 

 it will be neceHary to confider, that the Matter becomes va- 

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

 cording as the Tumours are varioufly difpofed and feated ; 

 for when they happen to be fuperficial and outward, the 

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

 a great meafure upon their Proximity and Nearnefs to the 

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

 rated, and call: off thro' the Pores; tho' in other moiil: Con- 

 ftitutions, the Matter will Ibmetimes be humid and moift. 

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

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

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

 rived from Blood, if a Horle 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 tlius it feems to be very plain and 

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

 duc'd of Blood, the Matter, in all Tumours, will therefore- 

 participate chiefly of thofe Juices from whence it is immedi- 

 ately derived. 



The next thin;: to be regarded in the Matter, is its Co- 

 lour, and this alio depends upon the Difpofition of the 

 Blood. \^ the Blood abounds with Choler or Gall, the 

 Matter will bsycllov/ i and ii will be mure or lefs io^ ac-
