Walt. Carol. 114, according to Furfh.) — " Leaves twice- 

 ternate, many-cleft. Partial umbels of three to live flowers. 

 Seeds roughidi " In dry fandy fields in Carolina, flowering 

 in April and May. Root annual. Purjb. 



6. S. trifoliatum. Three-leaved Carolina Honevvort. Mi- 

 chaux, ibid. Purfli n. 2. — " Leaves all ternatc ; leaflets 

 toothed ; the lower ones oval, with two or three lobes ; 

 upper oval-lanceolate. Umbel terminal, Italked, folitary. 

 iJeeds roundifh." — Found by Mirhaux in North Carolina. 



7. S. marginatum. White-edged Honevvort. Michaux, 

 ibid. Piirfli n. 3. — " Leaves pinnate ; the upper ones 

 qirinate ; leaflets all fefTile, lanceolate, entire, bordered with 

 ■white. General and partial involucrum wanting." — In wet

 11.7. (" Peucedanum redivivum ; Pallas Aft. Petrop. 1779. 

 V. 2. 252. t. 8. f. 1 — 3") — Leaves radical, doubly pin- 

 nate ; leaflets digitate, lomewhat whorled. Stem leaflcfs, 

 panicled, with numerous umbels. — In dry, muddy, fait 

 plains about the Wolga ; gathered by Pallas, whofe fpeci- 

 nien is before us. The root is perennial. Leaves all radi- 

 cal, appearing in the fpring, Italked, fpreading, three inches 

 long, doubly compound, the leaflets crowded as if whoiled, 

 in many fmooth, oblong, brilllc-pointed fegraents, all toge- 

 ther refembling fome feathery fort of Conferva. Stem ap- 

 pearing after the leaves are gone, twelve or eighteen inches 

 high, (lender, round, fmooth, bearing in Augufl a panicle, 

 alternately compounded, of (lender fpreading umbels, each of 

 from three to five rays. At the b:ife of each branch is a 

 fharp membranous-bordered leaf, or hraHea. Partial umbels 

 of five or fix capillary rays. General involucrum of two or 

 three fmall membranous leaves ; partial like it, but fmallcr.

 obfcurely ribbed. Some of the_/?OTOf/-.f in each partial umbel 

 do indeed appear to be abortive, whence perhaps Pallas re- 

 ferred this curious fpecies to Ptucedanum ; but we find no 

 traces of a wing to the feeds, to confirm that meafure.

 " Pallas Adt. Petrop. 1779. v. 2. 250. t. 7." — " Radical 

 leaves triply pinnate : thole of the item bipinnate ; leaflefs 

 brilUe-fhaped. General involucrum of many doubly pinnate 

 leaves." — Native ot Siberia. Pallas. AVe have not feen 

 the plate cited, but the involucrum is defcribed as doubly 

 compound and fetaccous. 



Two Britilh Liiinxan fpecies, tb.c inunJatum and verticil- 

 lalum, are removed, in the Flora Britannica, Irom the prefent 

 genus ; the former to Hvdiioiotvlk, and the latter to

 priety of thii alteration, as it is poflible to be on any qiief- 

 tion regarding the genera of umbclhterous plants. Sifin 

 itfelf is confidered, by fome botanills, as a doubtful geiuis, 

 and is reduced to Sium by Lamarck in his Diftionary,

 turned at each end, and hollowed underneath, to contain the 

 end-feizings : along the fides through which the pins are 

 driven, is a groove, large enough to receive part of the top-

 plants feem mod akin to Hvdxum ; fee that article. The 

 name appears to be compounded of a-uri; and T^i/xa, alluding 

 to the regular rows of pores ; but if fo, it ought to be

SISTRUM, a (acred mufical inllrument with the ancient 

 Egyptians ; and one that is itill ufed by the Abyflinians in 

 religious ceremonies. 



Spoil defcribcs it of an oval form, made in m.inner of a 

 racket, with three (licks traverfing it breadthwife, wliich, 

 playing freely by the agitation or beating of the inftrument, 

 yielded a kind of louiid, whicli, to the ancients, feemed 

 melodious. The upper part was adorned with three figures ; 

 that of a cat with a human face in the middle, the bead of 

 Ifis on the right fide, and the head of Nephthys on the left. 

 The reprefentation which we have given in the Plate of Mufic 

 was drawn from an ancient filtrum preferved in the library of 

 St. Genevieve at Paris. It Inu been difputed by the abbe 

 Winckelman, whether the (illrum was of very high antiijiiity 

 in Egypt, becaule it did not appear in the hands of (ucii 

 Egyptian ilatues as he had leen at Rome ; but as there is 

 one in the hand of a very aiicunt flatue of Ili'i, which 

 dodtor Pocoeke brought into England from Egypt, it puts 

 that point of mufical hillory out of all dilpiite. The 

 fillrum appears in the Ifiac Table ; and Apuleius makrx 

 an old Greek invoke an Egyptian priell " by the liars in 

 the firmament ; by the infernal divinities ; by the elements
