This general matter is feparable into fi- milar parts, or fuch as retain the fame nature and properties with the whole; and into diffimilar ones, or fuch as have fome dif¬ ferent properties from the whole. The latter reparation cannot be performed by triture or comminution, which only refolves a body into its integral parts} ’tis not the mortar, the file, or the mill, but a more powerful agent that muft refolve a body into. its effential parcels. Include any vegetable, or animal fub- ftance, in a proper apparatus, and commit it to the heat of a gentle fire ; firft a fine vapor rifes, condenfes, and turns into a lim¬ pid, taftlefs fluid. Augment the fire, and there comes over, in vapor, a liquor of a ftiarp taft, and urinous finell. Increafe the heat again, and a cloud of particles will afcend, and adhere, like cryftals, to the fides of the veffel. Thefe have nearly the taft of common fait, and eafily diffolve in water. Make the fire more fierce, a new cloud gathers, condenfes and falls, in yellowifli drops, into the receiver. Thefe will float on the furface of what came firft over, are inflammable, and bear a re- femblance to common oil. What now re¬ mains in the retort is black and crufty. Dilute this with boiling water, and ’twill give a faline taft thereto. Depurate and eva¬ porate the fluid, and it will leave fhin- ing cryftals behind it, refembiing fait, Af- a 4 ter
