tliief of die prop? rtic- uliicli he afcribcs to it. It is a com- 

 pound elallic fublle fubllaiicc, analogous to fulphur, nearly 

 approaching to the purell matter of lire or light, undeconi- 

 poi'able, conlifting of a faline acid principle and fire, com- 

 preiiible, capable of penetrating all vellels when red-hot, 

 Tind fenfibly heavy. It has an ailringent force, and com- 

 bines by means of lire with calcareous earth and the alkalies, 

 Hnd with metals when in the ilate of calx ; from its unit- 

 ing with fulphur, oils, and calcareous earth, he infers, that 

 the acid is united with fomething fnt or oi!v, (hence its 

 name acidiim p'wgue) and this oil fo tar flicaths its properties 

 as to prevent the acidity of its talle, S:c. Hence it is 

 evident, that the properties of this imaginaiy fubllance are 

 in part purely fitlitious, and for the rell a mixture of dif- 

 cordant qualities felected from thofe of the pure alkalies, 

 oxygen, and carbonic acid.

Ac 1 5, in Mythology, a beautiful fliepherd of Sicily, the 

 fon of Faunus and the oynipli Simaethis ; who, being be- 

 loved by Galatea, incurred the rage of Polyphemus, and had 

 his brains dafhed out flgaiuft a rock by tliis giant. He was 

 afterwards changed by Galatea into a river of the fame 

 name. The Sicilian authors fay, that Acis was the name 

 of a king, that reigned in this part of the ifland in a very 

 ancient period ; and, to this purpofe, they allege an iufcrip- 

 tion found near the river Acis, Aci Caftello. He is faid to 

 have been flain in a fit of jealoufy by Polyphemus, one of the 

 giants ot TEtna ; and thus they trace the origin of the fable. 



Acis, a river of Sicily, celebrated by the poets, viz. 

 Theocritus, (Idyll, i. v. 69) Ovid, (Faili, 1. 6. v. 468) 

 and Silius (1. xiv. v. 222), which flows from a cold fpring 

 at the foot of mount iFtna, and runs into the fea at the 

 diftance of about a mile from its fource. From the rapi- 

 dity of an arrow, with which it purfucs its courfe between 

 verdant banks, its name is derived. Bochart, (Geog. Sac. 

 1. i. c. 28. apud op. tom. i. p. 529. Ed. Villem.) deduces it 

 from the Syrian Jy^^^' <":^>'f"i to hajlen, or to he fivifl. 

 Its water is clear, and fo cold as to be dangerous to thofc 

 who drink it ; and never freezes, though it poireffes a degree 

 of cold greater than that of ice. It is faid to acquire a 

 poifonous quality from the vitriol with which it is impreg- 

 nated ; though It was formerly celebrated for the fwectnefs 

 and falubrity of its waters ; which, according to Theocritus, 

 were always held facred b)s the Sicilian (hepherds.

 the mouth of the river. There are fcveral places in this
