Observations. 
This Water is highly faturated with Salt, infomuch 
that any Meafure of it preponderates frefh Water 
under equal Surfaces, in the Ratio of Five to Four. 
It has alfo a wonderful Acrity, infomuch that 
being held in the Mouth for a fhort time, it con- 
ftringes it in like manner as Alum does. 
1 cannot (from the above Experiments , and the 
Appearances which refulted from them) conclude, 
that this Water is impregnated with any thing more 
than mere Salt, which is of a very acrid, alkaline Na- 
ture ; and fomething elfe, which may be of a com- 
pound Nature, partly fulphureous, and partly bitumi- 
G nous.
