 There is a curious cafe of ifchuria related by Dr, J, Senter, 

 in the Tranfaaions of the College of Philadelphia, Vol. I. 1793* 

 which continued more than three years, during which time, if 

 the urine was not drawn off by a catheter, it was frequently void- 

 ed by vomiting, and fometimes by the (kin; which could not 

 be accounted for, as Dr. Senter jultly obferves, but by toppof- 

 ing the exigence of the retrograde adion of fome parts of the 

 lymphatic fyftem. 



III. Communication from the Alimentary Canal to the Bladder, by 

 means of the Abforbent Veffels. 



MANY medical philofophers,both ancient and modern,have fuf- 

 pecled that there was a nearer communication between the flom- 

 ach and the urinary bladder, than that of the circulation : they 

 were led into this opinion from the great expedition with which 

 cold water, when drunk to excefs, pafies off by the bladder \ 

 and from the fimilarity of the urine, when produced in this haft y 

 manner, with the material that was drunk. 



The :ormer of thefe circumftances happens perpetually to 

 thofe who drink abundance of cold water, when they are much 

 headed by exercife, and to many at the beginning of intoxication. 



Of the latter, many inftances are recorded by Etmuller, t. xi. 

 p. 716. where firnple water, wine, and wine with fugar, and 

 emulfions, were returned by urine unchanged. 



There are other experiments, that feem to demonflate the 

 exiftence of another pafTage to the bladder, befides that through 

 the kidneys. Thus Dr. Kratzenftein put ligatures on the ure- 

 ters of a dog and then emptied the bladder by a catheter ; yet 

 in a little time the dog drank greedily, and made a quantity of 

 water, (Difputat. Morbor. Halleri. t. iv. p. 63.) A fimilar ex- 

 periment is related in the Philofophical Tranfadlions, with the 

 lame event, (No. 65, 67, for the year 1670.) 



Add to this, that in fome morbid cafes the urine has continu- 

 ed to pafs, after the fuppuration or total definition of the kid- 

 neys ; of which many inftances are referred to in the Elem. 

 Phyfiol. t. vii. p. 379. of Dr. Haller. 



From all which it muft be concluded, that fome fluids Lav* 

 pafled from the ftomach or abdomen, without having gone 

 through the fanguiferous circulation : and as the bladder is top- 

 plied with many lymphatics, as defcribed by Dr. Watfon, in the 



Philof.
