Method of preparing Salts and Saline 
Subst an ces 9 for the viewing their Con¬ 
figurations. 
I Difiolve the Subjedt to be examined in no 
larger a Quantity of River or Rain Water 
than I am certain it is fufficient to faturate. 
If it is a Body eafily diftblvable I make ufe of 
cold Water, other wife I make the Water 
warm, or hot, or even boiling, according 
as I find it neceffary. After it is perfectly 
difiolved, I let it reft for fome Hours, till, if 
overcharged, the redundant Saline Particles 
may be precipitated, and fettle at the Bottom, 
or £hoot into Cryftals ; by which Means I 
am moft likely to have a Solution of the 
fame Strength at one Time as at another; 
that is, a Solution fully charged with as 
much as it can hold up, and no more ; and 
by thefe Precautions the Configurations 
appear alike, how often fo ever tried: 
whereas if the Water be lefs faturated, the 
Proportions at different Times will be fub- 
jedt to more Uncertainty ; and if it be exa¬ 
mined before fuch Separation and Precipita¬ 
tion of the redundant Salts, little more will 
be feen than a confufed Mafis of Cryftals. 
The Solution being thus prepared, I take 
up a Drop of it with a Goofe Quill, cut in
