famed flower th:in the Cotton, by at leaft a third part of time. For the Big- 

 neifeofthe Flam:, the Cotton, and Thred, cait a Flame much alike- and the 

 mjh much leffe, and dimmer. Qjure, whether Woody and Wiekes both, as in 

 Torches, confume fafter, than the Wiekes Simple ? 



■We have fpoken of the Several Materials, and the Severall Wiekes : But 

 to the lofting of the Flame, it importeth alfo ; 'Not only what the Material 

 is, bur in the fame Material!, whether it be Hard, Soft, Old, New,&c. Good 

 Houjwives, to make their Candles burn the longer, ufe to lay them ( one by 

 one,) in Bran, or Flower, which make them harder, and fo they Coniume the 

 flower:Infomuch,as by this means, they will out-lait other Candles, of the 

 fame ftuffe, almoft Half in Half. For 3ran and F lower 1 hwe a Veitueto Har- 

 <len:So that both Age, and lying in the Bran, doth he^y to theLafting. And 

 we fee that Wax-Candles laft longer then T allow-CandleshzcmiQ'wax is more 

 firme, and hard. 



The Lofting of Flame alfo dependeth upon the eafie Drawing of the Non- 

 riftment; As we fee in the Cvitrt of England, there is a fervice which they call 

 All-nhht, which is (as it were) a great Cake of wax, with the wieke in the 

 Middeft-, whereby it cometh to paife, that the Wieke fetcheth the Nou- 

 rimmenr further off. We feealfo that Lamp laft longer,becaufe the veffell is 

 farre broader,than the Bredth ofa Taper, or Candle. 



Take aTurretedLamp of Tinne, made in the forme of a Squire The 

 -Height of the Turret being thrice as much, as the length of the lower, part, 

 whereupon the X4#?/> ftandeth : Make only one'Holein it, at the End of the 

 Return furtheft from the Turret . Reverfeit, and fill it full oPo/Vc, by that 

 Hole-, And then fet it upright again % And put a Wiek in at the Hole^ 

 And lighten it ; You mall tinde , that it will burn How , and a long time : 

 Which is caufed, ( as was faid'latr before , j for that the Flame fetcheth the 

 Nourtjhment a farre off. You ihall finde alfo, that as the Oile wafteth,and de- 

 fcendeth, fo the Top of the Turret, .hy little and little, filleth with Air k; 

 which is caufed by the Rarefaction of the oile by the Heat. It were worthy 

 rheObfervation, to make a Hole, in the Top of the Turret, md to trie, when 

 the Oile is almoft confumed, whether the Aire made of the Oile, if you put 

 to it a Flame of 'a Candle, in the letting of it forth, will Enfiame. It were good 

 alfo to have the Lamp made, not oiTinne , but of Glaffe, that you may fee 

 how the Vapour* or Aire gathereth, by degrees, in the Top. 



A Fourth point, that importeth the Lifting of the Flame, is the clofenefs of 

 the Aire, wherein the Flame burneth. We fee,that ifW/Wbloweth upon a 

 Cmdle, it wafteth apace.We fee alfo, it lafteth longer in a Lanthorn, than at 

 ■lar^e. And there are Traditions of Lamps, ?,nd Candles, that have burnt a very 

 long time, in Caves, and Tombcs. 



A Fifth Point, that importeth the Lafting of the Flame, is the Nature o{ 

 the Aire, where the Flame burneth • whether it be Hot or Cold;, Moift or 

 Drie. The Aire, if it be very Cold^ irritateth the Flame,and maketh it burn 

 more fiercely; ( As Fire fcorcheth in Froftie weather-, y Andfo furthereth 

 th$C ovftimption.Thz Afreonce heated/ I conceive J maketh the Flame burn 

 more mildly, and lb helpeth the Continuance. The Aire, if it be Drie, is in- 

 different : The Aire, if it be Moift, doth in a Degree quench the Flame-, (As 

 we fee Lights will go out in the Damps of Mines : ) And howfoever maketh 

 it burn more dully : And fo helpeth the Continuance.
