thus adding a Iccoiid fpccics to the cuiious genus before Ui. 

 With refpett to habit, indeed, this has httle rcfemblancc to 

 the original fpecies. It is a minute, browniOi, pcUueid mofs, 

 whofe foliage is all over dotted or reticulated. The root 

 feems annual. Sums none. Radical leaves few, ereft, li- 

 near, very narrow, a little dilated upwards, obtufe, entire, 

 without rib or vein : thofe which form njljeiil/j, at the bafe 

 of the frmt/lali, (hort, ovate, acute, with a rib or keel. 

 Siali red, fohtary, half an inch iiigli. Capfuk crcft,

TETRAPHOE, a name given by the people of Gui- 

 nea to a plant, which they give in decodtion as a cure for 

 fluxes. This plant grows alio in M;Jabar, where they ufe 

 the i-oots boiled in whey for the piles ; and in the colic they 

 give the root in powder, about a fcruple for a dofe. It is 

 called In this latter place luellia cadavaUi, and by Petiver 

 Kaiilhium Mdlabaricum capitulis lanugmofis. The ftalks of it 

 are woody and hoaiy, efpecially about the tops. Its leaves 

 ftand by pairs on (liort footftalks, and while young they are 

 hoary underneath, with a very foft and velvety down ; the 

 others are rough, like the fpotted lungwort, but feldom are 

 fo large ; the flowers grow in fpikes, and confift each of 

 fine green leaves filled with fcarlct filaments ; after thefe the 

 fruit ripens, and is a fort of woolly bur, covered with foft 

 and hooked prickles, very like the common Englifli bur- 

 dock, but not of a third part of the fize. Phil. Tranf. 



TETRAPILUS, a genus of Loureiro's, in his Co- 

 chinch. 6ll, named from Tslpa, and ^nXo?, a hat, or hood, 

 becaufe the four fegments of the corolla end each in a 

 hooded point. Every part of the dcfcription anfwers to the 

 genus Olea, fee that article ; except that the flowers are 

 dioecious (which indeed is of little confequence, fome of 

 the known fpecies being /ubjeft to have the ftamens and pif- 

 tils occafionally in fepai-ate flowers) ; and the berry is faid 

 to have two cells, with feveral feeds. Though Olea there- 

 fore is known to have two cells in the young germen, there 

 being here more than one feed, mufl: reduce Loureiro's 

 plant to Ligujlrjtm ; and it may prove very near L. japoni- 

 cum, Thunb. Jap. 17. t. I, though fcarcely the fame 

 fpecies. 



TETRAPLA, formed from TST^aTXo?, quadrupUx, four- 

 fold, in Church Hijlory, a Bible difpofed by Origen, under 

 foiu- columns, in each of which was a different Greek verfion, 

 w.v. that of Aquila, that of Symmachus, that of the Se- 

 venty, and that of Theodotion. 



Sixtus of Sienna confounds the tetrapla with the hexapla ; 

 but the tetrapla is a different work, compofed after the 

 hexapla, and in favour of fuch as could not have the 

 hexapla. 



Some authors are of opinion, that the order in which the 

 four verfions of the tetrapla were ranged, was different from 

 that in which we have rehearfed them ; and particularly, that 

 the Septuagint was in the firft; column ; but St. Epiphanius 

 fays exprefsly to the contrary, and places it in the third. 

 He even gives us Origen's reafon for putting it there, which 

 was, fays he, that the bell verfion might be in the middle, 

 that the others might be the more eafily confronted with it, 

 and correfted from it. 



Baronius, however, in his Annals for the year 231, takes 

 the Septuagint to have been in the third place in the hexapla, 

 but in the firft in the tetrapla ; but Epiphanius gives it the 

 fame place in both. See Hexapla.
