JfO S SIL S naturally and essentially compound, not inflammable, soluble in water.

Os this series of Foflils there is but one Class.

she bodies constituting this Class are,

The Metalic Salts,

Foflils not inflammable, but fusible in the fire, soluble in water, and separable again fromit by crystallization, impregnated with the particles of metals, and imprefling an acridand-nauseous sensation on the tongue.

she true origin of all these compound Salts is, that they are compos'd of the particles ofmetals, diflblvd by the acid of sulphur, and by means of water reduc'd into the form of aSalt, so that they very much approach to the nature of metals.

Of this Class there are two Orders, and under those three Genera.
