After this liquor had Hood more than two days expofed to the air 

 in my lludy, the weather being very warm, with a dry eaft wind, 

 and about half the moifture remained, I concluded that it then 

 moftly confirted of falts, which were too foft to coagulate, I there- 

 fore applied it to a moderate heat, and then I faw an incredible 

 number of faline particles formed in it, many of which were of fix, 

 and others of four fides. But whereas our common fait, dilfblved 

 in water, when it again forms itfelf into falts, affumes an exaft qua- 

 drilateral figure, or if a little of an oblong fhape of four fides, yet 

 each angle is always a right angle, or contains ninety degrees, as 

 far as the eye can judge ; on the contrary, thofe faline particles I 

 am now defcribing, were not only compofed of irregular angles 

 and fides, but their fides did rife up in a pyramidical form, like our 

 common fait, fo that they appeared to me like irregular quadrila- 

 teral cubes. But I muft needs fay, tliat none of the faline parti- 

 cles which I ever faw extrafted from plants of any kind, appeared 

 fo regularly formed in their cryftallization, or coagulation, as the 

 falts produced from the firft infufion of Tea, and which are repre- 

 fentedat/o-. ii,0, and^^. 12, P. 



After this, I took a parcel of my bell Tea, which I put into a 

 new glafs, and, by degrees, applied to it fo firong a fire that the 

 glafs was red hot, colleding, with all the care I could, the fpirit, 

 oil, and volatile fait, which proceeded from it. I then obfervcd 

 that the oil, as foon as it was cooled, was not only very thick, but 

 could not be rendered liquid, fave by heat. Upon examining this • 

 oil by the microfcope, I thought that its tenacity was occafioncd by 

 the extraordinary great number of volatile falts it contained, and 

 the number of thefe falts was fo inconceivable that it is impoflible 

 to give a true idea of them, fo as to conceive that fuch a fmall 

 quantity of Tea could produce fo many particles of volatile fait. 

 All thefe faline particles were of the fame fhape, that is, very long 

 and pointed at both ends ; thefe are reprefented at Jig. 13, Q.
