ACINACES, in antiquity, a Perfian weapon of the fword kind. The word is Perfian, tho' etymologilts affect to give it a Greek origin. Some reprefent the acinaces, as a kind of fpear or javelin ; others, with more probability, as a fhort crooked fword, fhaped like the Turkifh fcymitar. The figure was altered by Darius, and accommodated to that of the Grecian fwords. Horace calls it medus acinaccs, in regard the Romans confounded the Medes with the Per- fians. It was alio in ufe among the Scythians, where di- vine honours were paid it. Boxborn. Epift. p* 220. feq. V. Vqff. Etym. Lat. p. 5. Martin Lex. Philof. T. 1. p. 9. Suid. Lex. T. i. p. 84. Hefycb.

ACTINIA, in the hiftory of infects, a fmall fea-animal of a cylindric fhape, equally thick in all part's, and about half an inch long; its tail is divided into three parts, or termi- nated, as it were, by three points. It lodges itfelf in little cavities of rocks and of the larger fea-plants of the ftony kind, and only appears on their furface when all is quiet about it. Round the mouth are placed a great number of tentacula, like fo many conic rays, and difpofed in two or three feries fucceffively fhorter than each other : thefe are in a continual vibratory motion, and by that means draw fmall animals into its mouth for food. The whole animal is of a pale flefli colour, except thefe tentacula, winch have a beau- tiful variety of colours, red, yellow, blue, and many others. It is found on the coafts of the American iflands. There are a variety of fpecies, differing from each other in figure, colour, C3Y. but all of them furnifhed with nume- rous tentacula, or rays.

Vid. Pr'ingle, Ob- ferv. on Difeaf. of Army, p. 179. AIR (Cycl. and Suppl.) — It has been aqueffion among natural philofophers, whether the air contains an acid or not. Monfteur Helot gives a probability to the affirmative ; and it feems as if this acid wece of a vitriolic nature. See Mem. Acad. Sciene. 1737. p. 378 and 1740. p. 141, 142. Edit. Paris. If fait of tartar, or oil of vitriol, be expofed to the open air, thefe, tho* extremely different fubftances, will each re- ceive and imbibe fo great a quantity of matter from the air as vaftly to increafe its weight, without any other alteration in its nature than the diluting or weakening it. The fait becomes a fluid liquor, called oil of tartar per ricHquimn, and increafes to feveral times its quantity; and a vial .of oil of vitriol, nearly filled and left unflop'd, will foon be found to fill up of itfelf and run over.
In both thefe cafes, the aerial particles afforded to the ex- pofed fubftances, are only water ; but the air evidently abounds alfo with a great variety of other principles, which it may and does occafionally afford to other expofed fubftances, whofe pores are fo formed as to admit them eafily. Thus the mortar expofed in the joinings of old walls, from the particles it attracts out of the air, forms a peculiar fait ; and a deal fhelf, moiftcned with the liquor of fixed nitre, has been known to become froftcd over with perfect and pellucid cryftals of pure nitre, only from the imbibing, or regaining the neceffary acid from the air, in the fame manner as if fpirit of nitre had been poured upon it. A viol half filled with oil of tartar per deliquium, on being expofed to the air, will often form a fet of peculiarly figured cryftals round the veffel, a little above the furface of the water.
