particle, and tlien were, as it were, driven off from it, and when 

 they had got to about five or fix hairs' breadths from the fubllance 

 of the particle, they difappeared. All thefc globules, viewed by the 

 naked eye, exhibited the appearance of fmoke : foon afterwards, 

 feveral fmall luminous parts appeared on the particle, which by de- 

 grees increafed fo far, that through the microfcope, they gave me 

 the reprefentation of a piece of burning turf, with fome afliy parts 

 here and there covering its furfacc. 



But what I moll wondered at was, that what I have fiiid gave 

 the appearance of fmoke, did not difperfe itfelf in the air, nor 

 mount upwards, as we obferve common fmoke to do, but fell back 

 on the glafs. lb that round about this particle of fubftance, cidled 

 natural light, there was not only more moifture tlian before, but 

 at the diltance of half an inch from it, there lay a very tranfparent 

 moifture or liquor, confiding of minute round jiarticles of different 

 fizes, and thefe in fuch numbers, that it was wonderful to behold : 

 many of thefe feemed to be watery, others oily particles. 



After this particle had laid a whole night, I examined it again in 

 the morning, and then I law that the fubllance which feemed wa- 

 tery, was increafed, and that the minute globules, exhibiting the 

 appearance of fmoke, ftill iffued from the particle. I then carried 

 it into a dark place, to fee whether the fame kind of light was 

 emitted from it as 1 had feen the evening before, but I could not 

 diltinguiili any. 



After it had remained twenty-four hours in my clofet, expofed to 

 the air, I again examined it, but I could not perceive any thing 

 expelled fr®m it. I then lighted a candle, excluding the day-light, 

 that I might fee more acutely, and then I faw fome globules ex- 

 pelled, which I think was principally caufed by the heat of the 

 candle ; for I obferved, that all the moill part of the fubflance 

 which had been expelled, was evaporated, and fome faline particles 

 of irregular figures were coagidated.
