too far afFeded the Glands or Kernels about the up- 

 per Part of the Wind- Pipe; though indeed many 

 Horfes are afFefted with Swellings of the Glands of 

 the Throat, while they are at Grafs efpecially in 

 Winter, which continue long upon 'eni before we 

 fee them, or any proper Care is taken, infomuch 

 that they indurate or harden, and would turn out 

 like a boiled Potatoe ; and when thus hardened, 

 they are unfit to perform Secretion. But here it 

 may not be amifs to fhew the Reader the Form or 

 Strufture of a Gland, and then he may be the bet- 

 ter qualified to judge of Glandulous Diforders, which 

 are really very numerous ; and it is great Pity more 

 Pains is not taken to fet their Doctrine in a true 

 Light ; though of late Years we are better acquain- 

 ted with their Stru^flure and Mechaniim, from per- 

 ufmg the Works of the truly Ingenious Dr. Keil 

 upon the Subjeft. 

 A Gland The Ancients believed the Glands were as fo ma- 



.4eicribtd. ^ly Cifterns whicli contained certain Liquors, by 

 which the Blood being fermented, threw off the 

 Humours refined by the Excretory or diicharging 

 Dudls or Pipes : But as thefe Ferments mull necef- 

 ^farily mix with the Blood, fo they mull beexhaull- 

 ed, and carried off .by the Blood into the Veins ; 

 and becaufe ail the Liquors in the Body are fepa- 

 rated from the Blood, there m\i& be another Fer- 

 jnent to feparate more : But this fecond Ferment 13 

 as liable to the fame Fate as the firft j and therefore 

 there mufl be an infinite Series of Ferments in the 

 Body ; which is abfurd to imagine. 



If it fhould be objected that the Ferments are not 

 carried off with the Blood, they muil be Hopp'd by 

 ihe Strudure of the Glands ; but then there will 

 be a Secretion without a Ferment, which is now 

 the common Opinion. 



Some think the Glands are Tubes whofe Orifices, 

 differing in Figure, admit only Bodies of fimilar 

 Figures to pafs through them : But this (though a 

 .plaufible Conjedure) is dcmonilrably falfe ; For
