tnd a (hortnefiof ^eath ; they all went off, and In Five 
Days time (be feemed perfedly recovered. 
Thus we fee a Quantity of tbiij. i. of warm Water 
has been injefted into the middle Vtntcr of the fame 
Greyhound, within the Space of One Month, and if 
we may be allowed to judge of the Recovery, by a per- 
fed Ceflation of all Symptoms, as to outward Appear- 
ance, we muft then grant, that this Water was carried 
off thence, in ihe-^imer but to give an Account which 
way it was difcharged ( whether by Expiration, Per- 
spiration, Siege or Urine) (eems very difficult, and is 
beyond my Anatomy to explain ; only thus much I muft 
(ay, as to the latter j that having ordered the Grey- 
hound to be tied away, after One of the Two laft Ex- 
periments, within Two or Three Days, I obftrved the 
Boards of the Floor where (he lay, to be very wet, 
which I then imagined to be the Effed:s of the Injeftion, 
come off by Urine, if I may have leave to give a Con- 
jecture in a Matter of fo much Uncertainty, it lhall be 
this ; that as, Nature has furnifhed us with Vellels to 
bring off that Humour which is thrown into the Ventri- 
cles of the Brain, which by tarrying there would prove 
fatal to us, fb Ukewife (poffibly) there may be fonle 
DuSlm yet unknown (to me at leaft) which bek)nging 
to the Thorax, may convey off thence what Liquor 
arifcs, either from the Conden(ation of Vapours, or from 
the Rupture of Lymphatics, or any other way, in the 
Cavity mediately, or immediately, into the Blood; 
certainly thefe Experiments, as alfo the many Hiftories 
of Empyema's, and Dropfies of the Breaft , menti- 
oned by Pbyficians, as cured by large Evacuations by 
Urine, do (infome meafure) argue the Poffibility of this 
thing ; but whether in reality ttere beany fuch Paflage, 
or no, may in a little time be rendred lefs qu^onabie, 
than now it is, upon the Tryal of fuch Anatomical Ex- 
periments.
