moft to be Mufcnlar, and probably altogether unfit for 
lodging any fuch bodies hs Glands are. 
But at laft the Knife removed all thefe Difficulties, 
and he happily fucceeded in the Difcovery of the fol* 
lowing Glands, which are the Subject of this Book. 
Before he defcribes thefe Gland ulous Bodies, he pre- 
mifes a fhort Account of the Stru&ure of the Longitu- 
dinal and Lateral Sinus's of the Dura Mater 5 but adds 
little or nothing to what the Renowned Willis , and 
the Sagacious Vieujftns , have already faid on that Sub- 
jeft. 
In examining the Cavity of the Longitudinal Sinus, 
immediately under its membranous Expanfions, in the 
Area or middle of its Cord# , mention’d by Dr. Willis , 
(that is, the fmall tranfverfe Fibres, which like Ropes 
keep the Walls of this Sinus from being over-dilated by 
the influent Blood) our Author had the good Fortune 
to difcover a great number of Conglobate Glands, which 
are all contained by a fine and proper Membrane, as in 
a Bag. For the moft part they appear in Clnfters, and 
are feldom fcatter’d here and there. Their Figure is 
roundifh $ and in bignefs they equal a Silk- worms Egg, 
if infpe&ed as foon as the Body is opened 3 but if the 
Meninx be macerated in Vinegar for a Month, or more, 
they are bigger than a Millet Seed. In Old People, 
and in thofe who have died of a lingring Difeafe, they 
may be feen by the naked Eye, without any Micro- 
fcope, or previous Preparation. They are incompafled 
with fine Carnous Fibres $ whence they put on a pale 
Colour : But when thefe Fibres are much relaxed, as . 
happens in an Hydrocephalus, or Comatofe Diftempers of : 
*he Brain, they become white and very big.
