Note 3121 — BOOK XXXI. REMEDIES DERIVED FROM THE AQUATIC PRODUCTIONS.

See B. xii. c. 49, and B. xxiv. c. 28, for an account of gum resin ammoniac, a produce of the same locality. The substance here spoken of is considered by Beckmann to be nothing but common salt in an impure state. See his Hist. Inv. Vol. II. pp. 398-9, where this passage is discussed at considerable length. Ajasson, on the other hand, considers it to be Hydrochlorate of ammonia, the Sal ammoniac of commerce. According to some accounts, it was originally made in the vicinity of the Temple of Jupiter Hammon, by burning camels’ dung.
