I afterwards mixed water with the oil, and b}' the fire I mixed the 

 oil and water as much together as I was able, but in this I could 

 obfervc nothing except a few falinc particles, like thofe reprefented 

 at ^o". 0, I ; but thcfe I could not well dirtinguiih on account of the 

 oil, the water being evaporated. I alfo faw in the oil various par- 

 ticles, which I thought were falts irregularly joined together. 



Upon the caput mortuum, or fubftance left behind by the 'fire, I 

 poured fome clean rain water, and let it ftand for fome hours, that 

 the fixed falts it contained might be drawn ofF by the water ; after 

 this I poured off the water as clear as I could and expofed it to the 

 air in my clofet, the weather being calm and the funfl^ining bright, 

 but the water did not at firil evaporate : but, after llanding two 

 days and nights, I faw a great number of faline particles fwimming

 heat, and then I faw, as I may fay, the whole of it converted into 

 irregular faline particles, which were as tranfparent as glafs, and in 

 fuch numbers that they looked like a heap of fand. 



Upon breathing my warm breath on this newly formed fait it 

 again changed into a tranfparent fluid liquor. 



From thefe obfervations I neceflarily concluded that there was but 

 little volatile fait in Pepper, becaufe I obferved few particles of tliat 

 fiDrt in it. 



After this I took common white Pepper, becaufe I think that there 

 is no other ditFerence between M-hite and black Pepper, than that ' 

 the outward Ikin or fliell, which is fl:ripped olF the former, is left on 

 the latter. 



This Pepper I alfo put into paper and pounded it into fmall parts,^ 

 and infufed it in water. After the water had flood about two hours 

 I poured it ofi' as clear as I could, and in the evening placed it in my
