Salt whence derived, and hove diffufed. 59 
Bajket-Salt; fo that, in Reality, Rock-Salt , 
Sea-Salt, and Spring-Salt, are derived from 
one and the fame Original in the Bowels of 
Rocks and Mountains; and, upon the drift¬ 
ed Examination, they feem to differ no 
otherwife than by fome adventitious Mix¬ 
tures, as our Experiments evince, by {hew¬ 
ing that neither of them form any branch¬ 
ed Configurations; but when their Particles 
combine again after Diffolution, they con- 
ftantly compofe the fame Kinds of pyra¬ 
midal Cryftai Bodies, with Bafes that are 
either exaft Squares with four equal Sides, 
or elfe having two oppofite Sides longer than 
the other two, but always making a right- 
angled Figure. 
This Salt is conveyed by Springs and 
Rivers wherever their Waters can find a 
Paffage. Its fined Particles riling with Ex¬ 
halations from the Sea and other Waters, 
are likewife difperfed univerfally, and fa- 
t urate the Surface of the whole Earth: where 
entering the-Roots of Plants, they promote 
Vegetation, help to compofe their folid 
Parts, afcend with their Juices, and, ac¬ 
cording to their Mixture with them, pro¬ 
duce that amazing Variety of Taftes, Smells, 
and other Qualities. Some of this may be 
recovered in its original Form, by Art, from 
moff Kinds of Vegetables; while the reff 
becomes fo changed by being blended with 
other Subftances, as to appear in the Shoots
