Note 11 — BOOK VII.
Herbert Hoover translation
In this chapter are mentioned seven kinds of common salt:
SaltSal.
Rock saltSal fossilis.
"Made" saltSal facticius.
Refined saltSal purgatius.
Melted saltSal liquefactus.
And in addition sal tostus and sal torrefactus. Sal facticius is used in distinction from rock-salt. The melted salt would apparently be salt-glass. What form the sal tostus and sal torrefactus could have we cannot say, however, but they were possibly some form of heated salt; they may have been combinations after the order of sal artificiosus (see p. 236).
