nese, but also cast in larger and smaller, round and square, thick- 

 er and thinner, pieces, for other purposes, according as they may 

 be wanted for the fabrication of kettles, pans, and other utensils." 

 The copper exported by the Dutch is. according to Thunberg, 

 packed in long wooden boxes each containing one pecul. A car- 

 go consists of six or seven thousand chests. The bars, he says, 

 "are six inches long, and a finger thick, flat on one side, and con- 

 vex on the other, and of a fine bright color. Each bar weighs 

 about one third of a pound." One of the bars now lies before us. 

 It is nine inches long, flat on one side and convex on the other, 

 the upper side much blistered, of a dark carmine color, and 

 weighs 11 taels, 3 mace, and 8 candareens, or 15*12 oz. avoir- 

 dupois.

Spicis distinctis; spica staminifera unica gracilis longo-pedun- 

 culata squamo-bracteata cum squamis oblongis ohovatis subob- 

 tusis; pistilliferis ternis oblongis laxifloris erectis exserto-pedun- 

 culatis foliaceo-bracteatis, inferiore longo-pedunculata; fructibus 

 tristigmaticis elliptico-triquetris utrinque teretibus a! ternis sub- 

 conico-rostratis ore integris subrecurvis, squama ovata acuta cus- 

 pidata membranacea paulo longioribus ; culmis foliisque stibpu- 

 bescentibus. 



Culm 18-24 inches high, erect, rather slender, triquetrous, 

 leafy towards the root ; leaves short and lanceolate, striate ; bracts 

 sheathing, leafy, shorter than culm and enclosing the peduncle 

 of the upper pistillate spike ; staminate spike single, erect, exsert- 

 ed from the upper sheath, with oblong or obovate ohtusish scales; 

 pistillate spikes three oblong, filiform, erect, loose-flowered, the 

 two lower long pedunculate, and all sheathed ; stigmas three; fruit 

 elliptic-triquetrous, tapering to both ends, conic-rostrate, slightly 

 recurved at apex, with orifice entire, alternate and smooth ; pistil-

 leaves, and sheaths, slightly pubescent, pale green. 



From Louisiana through Dr. Sartwell. and a few years since it 

 came to me from Dr. Hale of the same state. It resembles 

 slightly C. anceps, but the fruit is much longer and more conic, 

 and appears a distinct species.
