in teacliiiig the art of rlietoiic. He was the inftru£lor of 

 Timotheus, fon of Conon, v. horn he afterwards accompanied 

 to feveral parts of Greece as his fecretary. He liad nume- 

 rous fcholars at Alliens, and was amply remunerated for 

 fome of his writings, particularly for a difcourfe which he 

 addrcfled to Niocles, king of Cyprus, for which he received 

 a funi equal to between four and five thoufand pounds of our 

 money. Though courted by the great, he had an ardent 

 mind in defence of wlial was jull and right. When Tliera- 

 rnenes, profcribed by the thirty tyrants, took refuge at the 

 altar, he pleaded in his defence, at the hazard of (haring 

 his fate ; and after the death of Socrates, when all his dif- 

 ciples look flight, he dared appear in mourning in the public 

 llreets of Athena. He paffed a long Kfc in peace and ho- 

 nour, and Iiiid reached his ninety-eighth year at the fatal 

 battle ofCluronxa, when, unable to bear the calamity wliich 

 had befallen his country, he abltained from all fnltcnance 

 for four days, and expired. It was mentioned, to his praife, 

 ■that he never, by writing or accufation, injured a fingle indi- 

 vidual. A llatu:- of bronze was raifed to his memory by 

 Timotheus, and another by his adopted fon Aphareus. 

 The ftyle of Ifocrates is pure, fwcet, and flowing : he was 

 extremely attentive to the harmony of his periods, and he 

 h reckoned by Cicero as the firft who introduced into 

 Greek profe that melody of whicli it is fufceptible. He 

 fpent a deal of time in polifliing his compofilions ; his pane- 

 gyric on Athens is faid to have coft him ten years labour. 

 Twenty-one of his di(couri'es remain, which have been diftri- 

 buted into the moral, thedehberative, the panegyrical, and 

 the agonillical. Moreri.

 Engl. Bot. t. 10S4. Bolt. Fil. 74. t. 41. (Subularia

 awl-ftiaped, femi-cyhndrical, rather fpreaduig. Capfules 

 roundifli, of two cells. Seeds granulated all over. — Found 

 under water, about the margins of alpine lakes in various 

 parts of Europe. In thofe of Wales, Scotland, and Weft- 

 moreland, it is abundant, making a fort of coarfe evergreen 

 turf, much below the furface. The root is perennial, tuberous, 

 throwing out many long fimple llbres. Leaves or fronds 

 •numerous, tufted, fimplc, awl-(haped, from three to twelve 

 inches high, rather fprrading upwards, and often recurved, 

 femi-cylindrical, fmooth, divided internally into four longi- 

 ;tudinal cells or tubes, with numerous tranfverfc partitions.

The bafe of each leaf is fomewhat dilated, and bordered 

 with a membrane, the frudificalion being fituated on the 

 inner fide, under the cuticle, that of the inner leaves being 

 male, the outer female. What fupports the anther in one 

 flower, the germen in another, may be termed eitiier a cply x 

 or receptacle. The ripe capfule is nearly as large as a fpht 

 pea, brovnifh, thin, and membranous ; we find it divided 

 into two cells by a tranfverfe ftrifture or partition, notwith- 

 llanding wiiat Sciireber has m.entioned to the contrary, 

 apparently from Oeder. The feeds are numerous, fmall, 

 white, rough all over with minute granulations. 



2. I. fetacea. Slender Quillwort. Lamarck Dicl. v. ^. 

 314. — Frond*- briftle-fliaped, nearly round, ereft. — La- 

 marck mentions this as very different from th.e former in the 

 (lendernefs and ftraightnefs of its leaves, which are only about 

 2i inches high. The root alfo is entirely fibrous, not tube- 

 rous. It was found by the abbe Bonnaterre, growing three 

 or four feet under water, in the lake of St. Andrcol, ou the 

 mountains of Aubrac.in Gcvaudan. We have had no other 

 tidings of this fpecies, but fliould expe6t to find it in Britain. 



3. I. uuilocularis. Indian Quillwort — Roxb, MSS. — 

 Fronds fomewhat triangular, ereft. Capfules elliptical, of 

 one cell. Seeds granulated on one fide, triangular on the 

 other. — Sent from the coaft of Coroinandel by Dr. Rox- 

 burgh. Koenig fent what appears certainly to be the fame, 

 in a younger ftate, to Linnaeus by the name of /. hidica, as 

 found in ponds on a fandy foilj in December. In thefe 

 latter fpecimens the root of each is a globole tuber. Fronds 

 about fix, creft, ftraight, flender, obicurely triangular, with 

 a broad membranous bafe. FruP.ificat'wn too young to be 

 difcernible. Dr. Roxburgh's fpecimens confift of feparate 

 fronds, larger than the former, as being more advanced, but 



otherwife cxaftly fimilar, the bafe of each winged with a 

 broad membrane, and lodging an elliptical, flightly com- 

 prefled, membranous, browniih capfule, from above half an 

 inch to near an inch long, of one cell, whofe infide is lined 

 with innumerable compreffed membranous ftalks, each bear- 

 ing a beautiful white feed, convex and granulated below, 

 triangular and fmooth above. A fponjy body, above the 

 capfule, but, in our fpecimens, disjointed from it, is lodged 

 in the fubilance of the leaf, and the fame is indicated by the 

 figure of the firft fpecies in Engl. Bot. in boih male and 

 female flowers, as well as by Linnsus in his Iter Scankum. 

 Having never had an opportunity of tracing the progrefs 

 of the fructification, we are not certain whether this be the 

 part called fometimes calyx, fometimes receptacle, but if fo, 

 the capfule is rcverfed. S.
