250 Experiments on Urine. 
In feurvy, and fome other putrid difeafes,.as they have 
been called, we make no doubt the appearances and proper= 
ties of this fluid are fufficiently remarkable, and we would. 
recommend it to be examined by thofe who may have op- 
portunities. 
Can internal ulceration and fuppuration be ‘deteéted in 
this way? In fome difeafes of the abdomen, accompanied 
with tumefaction, the urine has been met with of a white 
colour, as if mixed‘with pus; and in a few inftances, when 
this change has taken place, the enlargement has fuddenly 
fubfided.—Was this colour owing to pus ? and, if fo, was the 
pus taken up by the abforbents, or was it carried off by the 
kidneys, in confequence of fome dire&t morbid communi- 
cation? In children fubje& to worms, the urine has 
likewife been obferved to have at times a ee colour 3 
and this has been fuppofed to proceed fomehow from the 
chyle. This peculiar appearance is not to be confounded 
with what takes place in local affe€tions of the kidneys and 
bladder, where it alfo occurs, but is fufficiently underftood. 
We have had no opportunity of examining this kind of 
urine, and cannot, therefore, give any fatisfatory account 
of it. | 
We have thrown out thefe imperfe& hints, merely with a 
view to induce others to pay fome attention to a fubjed 
which has of late been much neglected, but which, in our 
opinion, is capable of affording great affiftance in the inyef- 
tigation and cure of many difeafes.
