tremity, by which they admit the fea water: as thefe ftand above one another on the main {talks, each receives its por- tion of fluid, and tranfmhs it without mixing with the reft, pure to that part of the ftalk where it join3 : they are all nicely jointed on to the main ftalk or trunk, and chat alfo is hollow as well as the leaves. The leaves of mod of the fea plants, on being examined by the microfcope, appear to be full of glandules and tubercles, which are in reality fo many' fmall pipes deftined to admit the fea water ; but in this plant, as that water is admitted in fufficient plenty by the extremities of the leaves, the reft of their furface is kept fmooth and perfectly even.

PHYRAMA, in the materia medica, a name given by fome of the old writers to the gum ammoniacum, particularly to that kind of it which was foft and ductile between the fingers. It is not clear that the gum ammoniacum of thofe times was the fame tiling which we now know by that name ; at leaft it is certain, that the other kind of it, which they called thrauma, or a?wnomacu?n thrauftum, was not j for Diofcorides defcribes this as being of a reddith-brown colour, and very friable ; and Avifenna fays, that it marked a fine yellow or gold colour upon paper. Thefe are properties by no means agreeiiig with our gum ammoniacum ; and if juftly appli- cable to that, muft prove that it could not be the fame ; and the characters given by Avifenna of its bitternefs, and mak- ing a yellow ftain upon paper, feems to make it the gamboge. This, however, by no means can agree with the other virtues attributed to it.
PHYSALUS, a name given by Rondeletius to a fpecies of fea infc£t, of ti\zfa,hpcndra ma' ina kind, fuppofed by fome to be the fame with the fcolapendra marina, or centimes of the Iriih fea, defcribed by Molyneux ; but this does not appear to be the cafe, on a ftrict enquiry. The phyfalus of Rondeletius has no mouth, whereas the fea certifies of Ireland has a remark- ably large one : that of Rondeletius is wider in the middle, and tapers at each end j but the Irifh kind is largeft at the head, and tapers from thence all the way to the tail. Ron- deletius's has tubercles on the back, but tie Iriih one has only hairy ftripes; and his is a poifonous animal, whereas that of Ireland was found in the ftomach of a cod-fifh, which had eaten it as food. The figure given by Rondeletius agrees alfo very well with the account lie gives, but not with the figure of that drawn upon the fpot from the Irifh fifh, and given in thcPhilofophical Tran factions. On the whole, nothing is more plain than that thefe are two diftinct fpecies of ani- mals, tho' of the fame genus. Phil. Tranf. N° 225. See the article ScolopendRA.
PHYSE TER, in ichthyology, the name of a genus of fifties of the plaglure kind, the characters of which are thefe : The teeth are crooked, and are placed only in the lower jaw There is one high fin or fpine on the back, and a fiftula or hole in the forehead. There are only two known fpecies of this genus; thefe are, 1. The phyfeter with the upper jaw longer than the under one, and with a long fpine on the back. The head of this fiih is fo large, that it is half as long as the body, and thicker than the thickeft part of it. The lower part of the upper jaw runs out two foot beyond the under one, and its upper part more than five foot. The eyes are remarkably fmall, fcarce longer than thofe of a haddock ; the fiftula or pipe, is placed a little above the center of the head ; it is divided into two channels, and covered with one common operculum ; the teeth are in number forty-four, and all of the fhape of a reaper's fickle, roundifh and a little flatted, thickeft and moft arched in the middle ; and at the end terminating in a cone very lharp-pointed ; the bafe is thinner than the middle of the tooth. 2. The phyfeter with a verv hi^h back-fin, with the tops of the teeth flat. This is a fpecies of whale, defcribed, as well as the former, by Sib- bald The head is very large; the fiftula, or pipe, is in the middle of the head ; the fin Hands fo high in the middle of the back, that it has been compared to the mizzen maft of a fhip. Artedi, Gen. Pifc See the article B*.L. <en a. The name phyfeter is of Greek origin, and is derived from the verb 9wr«w, to blow. It has this name from its quality of taking in a great quantity of fea water, and then blowing it out again with great force and violence. Suppl. Vol. II.
