QuiNTE, in French Mufic, is the name of the inftru- 

 mental tenor part in full pieces, ufually written in the 

 mezzo foprano clef on the fecond line. All the inilrumental 

 tenor or alto viola parts, in Purcell's time, were written in 

 this clef, as may be feen in his overtures and acl-tunes. 

 This was an imitation of France, where all the tenor parts 

 in Lulli and Rameau's operas are in the mezzo foprano 

 clef. 



QUINTELLO, Ttal. Quinque, Fr. a vocal or inilru- 

 mental compofuion in five parts, dialogued, and generally 

 a parte equak. The inilrumental quintets of Boccherini and 

 Mozart are fublime produttions : there is, perhaps, no 

 inilrumental mufic in which more genius and abilities are 

 manifeil, than in the quintets of thefc great mailers.

QUINTER, QuiNTOlEU, Fr. in the firll attempts at 

 harmony, was counterpoint in a feries of Jths, any two of 

 which, in aftertimes, would ruin for ever the reputation of a 

 compofer. 



QUINTESSENCE, quh,ta ejentia, in the old Cbemtftry, 

 properly denoted the fifth efTence, or the refult of five fuc- 

 ceffive dillillations. The term, now obfolete, was ufed to 

 exprefs the higheft degree of rectification to which any 

 fubllance can be brought. It alfo fignified a preparation 

 confining of the ed'ential oil of fome vegetable fubllance, 

 mixed and incorporated with fpii'it of wine. 



Thus, on a proper quantity, e. gr. of efl'ential oil of fennel, 

 pouring twelve times the quantity of pure alcohol prepared 

 per fe, they inllantly unite into one fimilar liquor, which is the 

 quintefience of that plant. 



The ancients were perfectly unacquainted with the method 

 of diflolving oil in fpirit of wine ; and even fome of the 

 moderns have queftioiied its reality : but the certainty of 

 the thing is eafily proved, from the inllance above, and from 

 a thoufand others. 



If fuch quintelfence be feveral times digefted, cohobated, 

 &c. the oil will at length be broken fo fine, as, like the 

 fpirit itfelf, perfetlly to mix with water ; which is one of 

 the mod extraordinary effecls in all chemiftry. 



After the like manner is made a quinteffence of camphor, 

 by only pouring on it fpirit of wine. 



QuintefTences, thus prepared, were fuppofed to have great 

 medicinal virtues ; on account of the pure and potent m- 

 gredients ufed in their compofition ; which retain, in a 

 great degree, all the virtues of the plants they arc procured 

 from : and hence their denomination. 



Boerhaave thinks, they might properly be called vege- 

 table fulphurs made potable, and raifed to their utmoft 

 degree of power and efficacy. 



Dry quinteffences may be made from the liquid ones, by 

 adding to them fome more efiential oil of the fame vegetable 

 from whence the liquid quinteffence was procured, with a httle 

 fugar, all mixed together, and dillilled, by a very gentle 

 heat, till all the moiilure is come over ; the matter remain, 

 ing is then a dry quinteflence. 



This form was deemed principally ufeful for traveller*, 

 failors, &c. inafmuch as it renders the quinteflence portable } 

 fo that the quantity, e. gr. of a piu'b point, (hall be an 

 efficacious medicine. 



QuiNTEs.SES'CE, in /llchemy, is a myfterious term, fignify- 

 ing the fifth, or lall and higheft effence, or power, of a 

 natural body. 



This is fuppofed to be, as it were, the foul drawn from 

 the grofs body and its four elements, by a moft perfeft 

 dillillation ; and, by means of which, the thing is faid to 

 be fpiritualized, /'. e. rendered exceedingly pure, fpirituous, 

 and, as it were, incorruptible. 



The ancients, who allowed nothing to be real but what 

 has a body, would have the loul of man to be a fifth element, 

 a kind of quintcifence without a name, unknown here below, 

 indivifible, immoveable, all celcitial, and divine. Fenelon. 



Quintessence of the Elements, is the hermetical mercury. 



QvisTKfiHK'acF. 0/ JVine, a term ufed by Glauber to ex- 

 prefs an efiential oil of wine, which he direds to be made 

 by a careful dillillation ; and which he is very fond of, as 

 having a power to meliorate, improve, and even to fpecificate 

 the poorer wines into the nature of thofe from which it was 

 obtained. 



This is one of the fchemes of Glauber, generally efteemed 

 an imprafticable one, though very plauGble in theory : but 

 though in general there is a difagreeable flavour in the quint- 

 effence drawn after his method, which is different from the 

 true flavour of the wine, and fpoils the liquor it is added to ; 

 yet, by proper care, there is a poffibihty of fucceeding fo 

 far as to render this extraneous flavour almofl imperceptible, 

 and produce an oil that will mend poor wines extremely, 

 and give a truly vinous flavour to fuch as are in them- 

 felves tallelefs. But whatever may be done by this method, 

 may alfo be done with much more certainty, and much lefs 

 trouble, by the concentration of wines by freezing. This 

 may be eafily praclifed in the wine countries ; and by this 

 means Burgundy, Champaigne, and other the moft valuable 

 Avines, may be reduced into thick extracts and robs, by the 

 means of which wines may be made in England ; a very 

 fmall quantity of thefe concentrated wines being fufficient 

 to convert the whole of any of the poor tallelefs and infipid 

 wines, which are of themfelves of little or no value, into the 

 very wine from which the rob was made ; and that in fuch 

 perfeftion, that the niceft judge cannot find out the dif- 

 ference. 



Thefe robs of wine, made and preferved upon the fpot, 

 would alfo be of infinite ufe in the wine countries, as they 

 might be kept to improve the wmes of bad years. Stahl,

QUINTI, Bay of, in Geography, a bay and harbour in the 

 N.E. part of lake Ontario, at the mouth of the Trent ; 

 formed by a large peninfula, confifting of the townfhips of 

 Ameliafburg, Sophiafburg, and Maryfburg, extending 

 eafterlv from an ifthmus, where is a portage at the head, or 

 W. end of the bay, to Point Pleafant, the eaiternmoft extremity 

 of the peninfula, oppofite to Amherfl ifland. The river Trent 

 difcharges itfelf into the head of the bay, weftward of the 

 portage, and fupplics it wit.h the waters of the Rice lake. 

 Weflward of the portage in lake Ontario, is the harbour of 

 Prefque Ifle de Quinte, now called NewcalUe. The fer- 

 tility of the foil about the bay of Quinte is generally al- 

 lowed. The land is rich and eafily wrought, and produces 

 feveral crops without manure ; 25 bufhels of wheat being
