The hairy Subftance, or fine Capillamenta , inclofed 
in the Pill-box, were difcharged along with the Urine 
of a Gentleman during a fevere Fit of Ardor Urinre ; 
the Gravel that came away was inconfiderable, fo that 
the Caufe of the Dyfury was chiefly owing to the 
hairy Subftance with the gritty Matter that adheres to 
ir, inflaming, by their Irritations, the Ureters and 
SphinEter Vejica , and Parts adjacent. For, not with- 
handing Thlebotomy, lenient Clyfters, Emulfions, 
Opiates, and fuch-like Remedies, were ftriCtly ufed, 
all proved ineffectual, till all this extraneous Sub-

pafl“ed alfo the Glandule Renales. For it is more 
probable, (with Submiflion) that they were extra- 
neous, than that they were generated in the Urinary 
Paflages, in an equivocal Manner. 
Thegreateft Objection, that offers to me, is, that it 
is judged abfolutely necefiary, that the Venre LaEle<c 
fhould be fmaller than the fineft Artery in the Body, 
that nothing might enter, which might flop Circu- 
lation of the Blood. Alfo, 
That the Mouths of the LaEteals , which are open 
into the Cavity of the hitejlines , (from whence they 
receive their Chyle) are fo fmali as not to be feen by 
the beft Microfcope in dead Bodies. 
To obviate thefe Objections, may not the Mouths 
of the LaEteals be perceptible in living Bodies, when 
diPated, diftended, and turgid with Chyle ? And may 
not thefe Capillamenta, when relaxed with any Hu- 
midity, become very flexible, pliable, and fufccptible
