fo elegant as to be imitated in the Carvings of the antients j and moderns.
The antients have not only called the herb bears-breech by this name, but alio a thorny tree growing in Egypt. Theo- phraftus mentions the Egyptian Acanthus as a robuft fhrub ; and Ifidore, fpeaking of the tree which produces myrrh, fays, in the words of a very antient author, that it is a 1 robufl fhrub, growing to five cubits or more in height, and fome- what refembluig the Egyptian Acanthus. Diodorus Siculus, and Diofcorides alfo, compare the myrrh-tree to the Acan- thus. It is very evident this could not be meant of the herb Acanthus, though the fame name is made to exprefs it. The fame Ifidore, however, afterwards confounds this fhrub with the plant of the fame name, faying, that the Acanthus of E^-vpt was a tender plant, always green, full of prickles, and having large leaves, and bending or flexile ftalks. Servius alfo runs into the fame error, and fuppofes the Egyptian and common Acanthus to be the fame plant. An accurate examination of the antient writers will, however, fhew very plainly, that they meant two very different vege- tables under this name ; the Acanthus of Virgil, and the Egyptian Acanthus of Theophraftus % being two wholly dif- ferent plants. Virgil mentions the Acanthus as being an ever- green plant, and producing berries, or a fmall round fruit, Baccas femper frondenth Acanthi, are his words : and Theo- phraftus tells us, that his Egyptian Acanthus is a prickly tree, and bears pods like thofe of beans. It is plain, that the Acan- thus of Theophraftus, is the acacia, a tree, from fome fpecies of which, we have the gum Arabic now in ufe ; and the Acanthus of Virgil, mentioned in this place, feems to be the Cyrenian lotus, which Herodotus fays is like the Egyptian Acanthus. Thus we find a third plant brought into the world, under the fame name : and this lotus, called by fome Acanthus, was found in Egypt, as well as in Cyrene, and had the term Acanthus at firft annexed to its name, by way of a diftinclive epithet, though it became afterwards ufed fingly for it, the original name lotus being forgot. The epithet Acanthus was ufed to this lotus, becaufe it was prickly. De- ' metrius, in Athensus b , when he defcribes the Egyptian Acanthus, is to be underftood alfo to mean this plant, he allowing that a round fruit, which Virgil calls a berry, not the pod, as Theophraftus's Acanthus muft have had. Servius rightly underftands the account the antients give of the Cy- renian lotus, or Acanthus, which he allows to have been a true lotus, and only called Acanthus, becaufe prickly. The Latins, as well as the Greeks, having ufed both the fubftan- tive Acanthus, and the derivative adjective Acanthinus, to exprefs any thing prickly, or befet with thorns. Acanthium gummi was an old name for gum Arabic; becaufe produced by a thorny tree : and Pliny calls the leaves of the euphorbium plant Acanthina \ not becaufe they were like thofe of the Acanthus, but becaufe they were prickly. — [ a TheophraJL de Arboribus. b Athenaus, 1. 5.] ACAPATLI, in botany, a name ufed by fome authors for the plant which produces the long pepper ufed in medicine.

ACARAUNA, in zoology, an American fifh, of which there are two fpecies ; the one called Acarauna, without any addi- tion ; and the other the Acarauna quadrata^ or fquare Aca- rauna ; and by our failors, the Old wife.
