3\(aturall Hifiory : 



Pulfes. A Piece of Wood,oi the Bignefle of an Arrow,and about a F ingers 

 length,was fet up in the Middeft,and the Spirit of IF//^ burnt to the fpace of 

 94 Pulfes. So that the Spirit of Wine Simple, endureth the longeft^ And the 

 Spirit of Wine with the Bay- fait, and the Equall Quantity of Water ere the 

 fhorteft. 



Confider well,whether the more fpeedy Going forth of the Flame Joe caufed, 

 by^ne Greater Vigour of the Flame in BwmttgiQx by the Refiftance of the Bo- 

 dy mixed,znd the Averfion thereof to take Flame: Which will appear by the 

 Quantity of the Spirit of Wine, that remaineth after the going out of the 

 Flame. And it feemeth clearly to be the latter-, For that the Mixture of 

 Things leaft apt to burne, is the Speedieft in going out, And note, by the 

 way, that Spirit of Wine burned, till it go out of it felf, will burn no more-, 

 And tafteth nothing fo hot in the Mouth as it did-, No nor yet fowre , ( as 

 if it were a degree towards Vinegar ) which Burnt wine doth; but flat and 

 dead. 



Note, that in the Experiment of Wax aforefaid, the Wax dilTolved in the 

 burning, and yet did not incorparate it felf, with the Spirit of Wine, to pro- 

 duce on Flame $but wherefoever the Wax floated,the Flame forfook it,till at 

 laft it fpread all over,and put the Flame quite out. 



The Experiments of the Mixtures of the Spirit ofWineenfamed,zxe Things 

 of difcovery, and not of Ufe ; But now we will fpeak of the Continuance 

 of Flames, fuch as are ufed for Candles, Lamps, or T apers -, confifting of In- 

 flamahle Matters, and of a Wiek that provoketh Inflamation. And this im- 

 porteth not only Difcovery, but alio life and Profit -, For it is a great Sa- 

 ving in all fuch Lights, if they can be made as faire and right as others , and 

 yet laft longer. Wax Pure made into a Candle, and Wax Mixed feverally in- 

 to Candle fluff e, with the Particulars that follow-, ( viz. Water, Aqua-vita, 

 Milk, Bay-falt^Oyle, Butter, Nitre, Brimftone, Saw-duft,)'iivery of thefe bear- 

 ing a Sixth Part to the'^fx -, And every of thefe Candles Mixed, being of 

 I the fame Weight and Wieke, with the Wax Pure, proved thus in the Burn- 

 I ing, and Lafting. The Swif teft in Confuming was that with Saw duft; 

 | Which fir ft burned faire till fome part of the Candle was confumed, and the 

 j?*Duft gathered about the Snafte-, But then it made the Snafte big, and long, 

 Tand to burnduskifbly , and the Candle wafted in half the time of the Wax 

 | Pure.The next in Swiftneffe, were the Oyle,md Batter, which confumed, by a 

 ! Fifth part, fwifter than the Pure Wax.Jhen followed in Swiftneffe the clew 

 Wax it felf. Then the Bay-Salt, which lafted about an Eighth part longer 

 rhan the Clear e Wax. Then followed the Aqua-vit&, which lafted about a 

 Fifth part longer than the Cleare Wax. Then follow the Milk, and Water, 

 with little difference from the Aqua-vit<e,but the Water floweft. And in thefe 

 foure laft, the Wieke would fpit forth little Sparks. For the Nitre, it would 

 not hold lighted above fome Twelve Pulfes •• But all the while it would fpit 

 out Portions of Flame, which afterwards would goe out into a vapour. For 

 the Br w: ft one would hold lighted,much about the fame with the Nitre-^Bat 

 then after a little while, it would harden and cake about the Snafte:, So that 

 the Mixture ot Bay-falt with Wax , will winne an Eight part or the time-of 

 Lifting, and the Water a Fifth. 



A iter the Severall Materials were tried, Triall was likewife made of fe- 

 verall Wiekes^ As of Ordinary Cotton-, Sowing Thred^Rufh; Silk; Straw-., and 

 Wood. The Silk, Straw, and Wood, would flame a little, till they came to the 

 Wax, and then go out:of the Other Three, the Thred confumed fafter than 

 the Cotton, by a Sixth part of Time : The Cotton next : Then the Rujh con- 

 fumed
