fufed in oyder-daell lime-water was found to have 
lofl almod three grains : that in Carlfbad water 
twenty-two grains : that in medicated urine four- 
teen grains : but that infufed in the urine of the 
man in health had increafed three grains. Thefe ex- 
periments therefore leave no room to doubt of, either 
the folvent power of the Carllbad water itfelf, or 
that of the urine of thofe who drink thefe waters. 
Our author has a very curious remark in relation 
to a perfon who laboured under the done, and who 
drank thefe waters for two months. He daily voided 
with his urine a large quantity of white vifcid mucus ; 
which, after filtration of the aqueous parts from it, 
was found to be a white earthy powder, rubbed off 
as it were from a done. The quantity of this 
powder faved during the fpace of a month amounted 
to. more than three ounces. If feme of this powder 
v/as put into the urine of one who drank Carlfbad 
water, it was immediately converted into a pultace- 
ous fubdance ; but if into that of one, who did 
not drink this water, it fell quite undidolved to the 
bottom of the veffel. 
Dr. Springsfeld obferves, that the Carlfbad water 
has great power in diffolving the tophaceous crud, 
which frequently covers the teeth. During the courfe. 
of thefe waters, this crud mod generally feparates 
from the teeth, and falls off. 
However great the power of thefe waters are in 
diffolving the done in the bladder, they have a quite 
contrary effed upon gall dones. So far from dif- 
folving thefe lad, our author has frequently found 
that thefe waters envelope them with their topha- 
ceous crud. Our ingenious brother Dr. Whytt has 
obfervcd.
