difeafe finally goes off much more fafely by this means, than when violently thrown off at once by aitringents. The double Tertian requires the fame method of cure with the fimple onej for which lee the articles Peruvian Bark, and Ague. Junker's Confp. Med. p. 366.

Continual Tertian, in medical writers, a term ufed to exprefs a kind of compound fever, which has paroxyfms fomething like thofe of the .Tertian, but in which the heat never goes wholly offj but is often (o extream, as to continue in great violence from one fit to the time of another. There are three fpecies of thefe compound fevers ; they are all compofed of the intermittents of the I'everal periods, and of an acute fever : The firit is the continual quotidian, the fecond this continual Tertian, and the third the continual quartan. The firit of thefe is the fame with the catarrhal fever of the benign kind. The fecond here treated of, is what was called by the antients, the extended Tertian. For the continual quartan, fee the article Quartan.

Signs of it. The paroxyfms are begun in the fame manner as in the Ample Tertian, that is, by a ihaking coldnefs ; and this is fucceeded by a heat which is at firit very violent, but after- wards grows more and more languid, yet never goes wholly off, but continues, in fome degree, to the accefs of the next paroxyfm. In this difeafe the appetite is loit, and the ftrength fails very fenlibly, the fleep is troubled and unlbund, and there is a continual head-ach ; there is a quick pulfe at all the times of the fever, and a drynefs of the mouth and tongue, with great thirlt. Junker's Confp. Med. p. 396. Perjbns fubjecl to it. This fever is very often the confequence of a common iimple Tertian, when injudicioufly treated, efpecially when it has been fupprefled by giving hot medicines juft before the coming on of the fit, or when the patient has been cooled in the time of the fweat, or has been blooded ■ during the time of the difeafe ; it fometimes alfo attacks per- fons who have had violent cutaneous humours, as the itch, 6r>. ftruck in ; and fometimes the air alone gives it, from be- being full of fermentative particles.

Prognojiics in it. When the difeafe is of this epidemic kind, and arifesfrom faults in the air, it is always attended with greater- danger, and has worfe fymptoms than when proceeding from other caufes ; in this cafe it is fometimes attended with purple fpots on the breaft and other parts. When treated cautioully, and with a gentle regimen, it very often changes to a common intermitting Tertian, and is then eafily cured ; but even from this Iefs dangerous ftate, it fometimes changes into a hectic, when it has been treated with large dofes or abforbents under that form j and finally, when it is treated with the common hot medicines and regimen, it too often degenerates into a violent and dangerous acute, and uiually inflammatory fe- ver.

Method of Cure. Before the coming on of every fit, the patient fhould take a fcruple of a powder, prepared of diaphuretic an- timony, oifter-ihells fated with juice of lemons, nitre, and tartarum vitriolatum, each in equal quantities ; and while the heat continues violent, he muft drink plentifully of warm and weak liquors ; and when this violent heat is gone off, he muft be kept in a gentle fweat r by the milder alexipharmics, till the return of the paroxyfm again.

In cafes where the heat is very -violent;, and the temperament of the body is hot and plethoric, the acids, fueh as lemon- juice, and the like, are of very Angular fervice. During the whole courfe of the difeafe, the bowels muft be kept open by all means; but they muft not be ftimulated ; and as the force of the diftemper wears off, more powerfully laxative medi- cines are to be given, and that at fuch times that their effect may not be over at the time of the accefs of the paroxyfm. The bark can properly have no place in the cure of this dif- eafe ; and after the cure of it by the means above prefcribed, the patient muft continue the ufe of fome of the medicines, and muft harden himfelf to the air by degrees,: for fear of a re- lapfe.

TERTIAN ARIA, in botany, a name given by fome authors to the fcutellaria,. or hooded willow herb. J.Baubin. vol.3. P- 435-

TERTIAS, a word ufed very frequently in the writings of phy- ficians, with the addition of ad\ but it is capable of a double fignification. Ad Tertias is often ufed to exprefs how far the liquor is to be boiled away in medicinal decoctions ; yet it may in this cafefignify cither the boiling to two thirds, or to one third part, of the whole. The more ufual fenfe, however is to boil away one third part of the original liquor, and in the fame manner to fill a veflel ad Tertias> does not fignify to fill a veflel one third part full, but two thirds, leaving only one empty.

TERTIUM SV, a third fait,, a term ufed in chemiftry to ex- prefs a fait refulting from the mixture of an acid and an alkali, which partakes fo of the nature of both, as to be itfelf neither acid nor alkali, but neutral.

It is alfo ufed for a third part of any thing, as un Terzo di bat- tuta, a third part of the bar. See the article Trto. TERZOLA, in botany, a name by which fome authors have called the eupaiorium cannabinum, or water hemp acrimony. Ger. Emac. Ind. 2. TESSARACONTA, TtaactpaxovTa, among the Athenians were forty men who went their circuits round the feveral bo- roughs, and had cognizance of all controverfies about money, if not above ten drachms ; as alfo of actions of aflault and bat- tery. Potter, Archseol. Grxc. T. j. p. 122. TESSARACONTERIS, in the naval architecture of the an- tients, a word ufed to exprefs a fort of galley, in which there were no lefs than forty tires of rowers one above another. Many have doubted whether fuch monftrous veflels as thefe were ever built ; but we have abfulute accounts of one fuch of Philopater's, which muft have required above four thouiand men to manage the oars.

Ptolemy Pbiludelphus is faid to have had one with thirty tires of rowers, requiring three thouiand men ; and we have ac- counts of another at the fame time of twenty tires, requiring two thoufand : But tho' fuch veflels as thefe were really built, we are not to fuppofe they were common. The triremes, or thofe galUes which had three tires of rowers were found the moft ferviceable of all others^ and from thefe they buili pretty frequently up to the enneeres, which contained nine rows or tires i and thefe were the largeft ever brought into common ufe, as is fully proved by Meibom againft Salmafms, on the authority of Pliny, Plutarch, and Polybius. Meibom. de Trirem.

This author has alfo taken off much of the imaginary height neceflary, according to common computation, for thefe vef- fels, having found a more convenient way of placin"- the rowers. 1 ESSARACOSTON, Tt?o-xfa,Karo v, in antiquity, a folemnity kept by women on the fortieth day after child-birth, when they went to the temple, and paid fome grateful acknow- ledgments for their fafe delivery.

into regular figures. TEbSELARIl, among the Romans, artificers of chequered

or mofaic work. See the article Mosaic, GycL TEST, {Cycl) in metallurgy, is a veflel of the nature of the coppel, ufed for large quantities of metals at once. The cop- pels or fmall veflels made of aihes, ferve for operations of this kind, when fmall quantities only are concerned j but when larger are worked on, veflUs of a larger fize and coarfer tex-^ ture are employed, which are diftinguifhed by the name of Tejls.

Thefe are ufually a foot and half broad,, and are made of wood-afhes, not prepared with fo much care as for coppel- making, and mixed with finely powdered brick- duft ; thefe are made into the proper fhape either by means of an earthen veflel of proper dimeniions, or only an iron ring. To make them in the firft manner, an earthen veffel is to be procured, not glazed within, and by its depth and breadth proportioned to the quantity of metal to be worked ; the in- fide of this veflel is to be well moiftened with fair water, that the afhes to be put into it may adhere the better. Put into this veflel, thus prepared, the afhes and brickduft before-men- tioned, and firft moiftened either with water alone, or with water with a little white of an egg mixed in it \ let the quan- tity of this be fo much as will half fill the veflel, then prefs the mafs with a wooden indented peftle, or, if not for a very large Teji, with a wooden cylinder, only of an inch thick : When thus prefled down, add frefh afhes, and prefs them in a fecond time, as in the making of coppels, and repeat this addition of frefh afhes till the earthen veflel be nearly full ; then remove the fuperfluous afhes with an iron ruler, and let the inequalities remaining at the border be fmoothed with a wooden ball rol- led round about. This done, you are to cut the cavity with a bowed iron, that you may have a broad fpherical feg- ment, not very deep : And laftly, by means of a fieve,. ftrew this cavity carefully and regularly over with dry afhes of bones of animals, ground extremely iine a and fqueeze thefe
