It has a fait tafte when firft taken from the water, 
and is made ufe of by the inhabitants for cleaning 
of teeth and fcouring filver : it is called Baden 
Fiaum. 
Tho’ this water does not depofit any fediment, 
yet it is remarkable for the fpeedy and ftrong incruft- 
ation of all bodies, which are put into it. Little 
plaifter figures are fold here, on purpofe to verify the 
experiment ; which, tho’ perfectly white when put 
into the fpring, are, in eight-and-forty hours, en- 
tirely covered with a yellow incruftation. The fame 
effedl is obferved on the pipes and channels, thro’ 
which the water is conveyed. If care were not taken 
to clean them four or five times a year, they would 
be intirely choaked up ; and in fome parts, where it 
has not been neceftary to clean them fo often, I have 
feen them covered with an incruftation two inches 
thick. In furrounding and covering thefe wooden 
pipes, they do not change the nature of the wood ; 
but it is obfervable, that they add great hardnefs and 
folidity to it : fo that it is affirmed a piece of deal will 
laft a hundred years in this water. The head fpring 
is cleared out once in 30 or 40 years, with a very 
great expence : at which time they are obliged to 
break off all the ftony incruftation, which had been 
made by the water fince the laft cleaning ; and if 
negledted would (as it has fometimes actually done) 
choak the paffages, and oblige the fpring to find 
vent in fome other place. The incruft ations formed 
by thefe waters are of different kinds : that, which 
is made in the troughs and pipes, thro’ which the 
water is conveyed after it comes above ground, is of 
a light fandy nature, of a loofe contexture, and a
