lion, if not in the difUn&ion of the fpecies. Tn fome fpe- cies it is made of a feries of little points, or holes, as appears to the eye j of this nature is the linen in eels, &c. In fome others it is formed of a fort of duct, running along the cen- ter of a great number of fcales. This is its ftructure in the generality of fifties. Jrtedi's Ichthyology. This line, in various kinds of fifh, varies alfo in regard to number, fituation, figure, and other properties. In regard to number, there is no line obferved in the fyngnathi and petromyza, in almoft all other fifh there is one on each fide ; and finally, in fome there are as it were two lines on each fide : an inftance of this we have in the ammodytx. In regard to the fituation, the differences are thefe. i. In fome ic is near the back, as in the clupea, falmons, pearch, and the like. 2. In others it is placed nearer the belly, and runs parallel with it, as in the cyprini. 3. In fome it is placed in the center of each fide between the back and the belly, as in the caraflius. 4, In fome it is placed againft the interfaces of the mufcles, or the fpina dorfalis, as in the murasna ; and 5. In fome it is placed above the inter- ftices, as in the ammodytae, &c. It has been fuppofed, by many, that this lima lateralis was always parallel to the in- terftices of the mufcles, but this is evinced to be an errone- ous opinion, by the observation of the pearch and mackrel. In regard to the differences of figure, this line is in fome ftrait, as in the coregones, falmons, &c. 2. In others it is crooked, as in the cyprini, the pearch, c?r. and in the ge- nerality of fifh is fmooth to the touch, but in fome it is rough and accelerated, as in the trachurus and pleuronectl.

Lines, in mulic, is ufed for thofe ftrokes drawn horizontally on a piece of paper, on and between which, the characters and notes of muiic are difpofed. Their number is commonly five, when another is added for one, two or more notes, it is called a leger line. See Leger.
Some fay that it is to Guido Aretine that we owe their in- vention : they are very commodious, and greatly afiift the imagination in diftinguifhing the low notes from the high. Upon their firft introduction, the lines only were ufed, and the fpaces between them intirely negleited. BroJJ'ard. Originally thefe were as many lines drawn for a fong, as it required notes afcending ; but at length the notes being placed in the intervals of the lines, thefe were reduced to four ; fo that there were nine places or degrees for nine dif- ferent founds, which was their extent : at laft they raifed the number to five, of which the loweft is reckoned firft j and hereon they placed the characters for eleven different founds, including the fpaces above the fifth and below the firft ; and at the lame time they had the liberty, at pleafure, to add more lines if the fong ran to a greater compafs.

LING, in ichthyology, the Englifh name for a kind of fifh, which is a fpecies of the afellus, according to the generality of authors, and is generally called afellus longus. Accord- ing to the new Artedian fyftem, it is a fpecies of the gadi, and is diftinguifhed by the exprefiive name of the gadus, with two fins on the back, with a bearded mouth, and with the upper jaw longeft. See Asellus and Gadus. Ling is efteemed, both frefh and cured for the table. It is » a long bodied fifh, more approaching to the merlucius or hake, than to any other fpecies. It is covered with very fmall fcales which adhere clofely to the ikin. The back and fides are of a blueifh or greenifh brown, and the belly white. Its head is flat and large, and its fnout confiderably lonf. The upper jaw is longer than the under, and both are fur- nifhed with feveral rows of fhort teeth, and the lower with one range of longer. And in the palate there are a large number of fmall teeth, among which there are four or five
large and long ones intermixed. The mouth
opens very
wide, and in the angle of the lower jaw has a fingle fhort beard. It has two fins upon the back, one near the head ; the other not far behind it, and reaching down almoft to the tail. The gill fins are fmall, the belly tins are placed high, and the tail is not forked. See Tab. of Fifhes, N J 28. and Ray's Ichthyog. p. 175.

LINGUADO, in zoology, the name of a Weft-Indian fifh, in fhape refembling a foal. Its mouth is furnifhed with very fharp teeth, but has no tongue. It has large gills, with two fmall fins annext near their bottoms to the under part, or belly. It is of a pale ftone colour, and is cloathed on the back with very fmall fcales. Its tail is almoft fquare in fhape, and made of a very thin fin. It lives in fhallow water, and keeps clofe upon the fand. It, upon the whole, very much approaches to our foal, but principally differs in that the fins under its gills terminate in a fmall filament. Marggrave's Hift. Braf. p. 71. LINGUATULA, in zoology, the name of a fpecies of fifh, fomewhat refembling the foal, but fmaller and fhorter, and much inferior to it in tafte.
