I made the like Tryal with ratified &yl of Turpentine , With i 
sot unlike fuccefs. The fame Experiment I tried more than 
once with highre&ifi’d Spirit of Wine , which did immediately 
deftroy all the light of the Wood , that was immerfed in it- 
and having put a little of that liquor with my finger upon a part 
of the whole piece of Wood, that (hone very vigoroufly, it quick- 
lydid, as it were 5 quench the Coal as tar as the liquor reach’d; 
nor did it in a pretty while regain its lominoufnefs i* ( which whe- 
ther it recovered at all, I know not; for this Trial beingmade 
upon my Bed , I fel afleep , before I had waited long enough to 
finifh the Obfervation. )

Air , when that is greater than ordinary , fo neither is a piece of 
shining Wood to be deprived of its light by the fame quality of

As much of this Observation p as concerns theCW, will be

I took a fmall piece of Shining Wood , and put it into a {len- 
der Glafs-pipe , fialed at one end , and open at the other , and 
placed this Pipe ina Glafs Vefifel , where X caufed to be put a 
ifrongly frigorifick mixture of ice and Salt , and hiving kept it 
there full as long , as I thought would be requifite to freeze an 
Aqueous Body , f afterwards took it oat , and perceived not any

mixture fhoald not deceive me , I had placed by this Pipe ano- 
ther 3 almoft filled with Water , which I found tobe turn’d into 
Ice ; and though X fuifered the Wood to remain , a pretty while 
after, expofed to fo intenfe a Gold, yet when I took it out , it 
continued ihining , and, if X mudvmiftake not , it ceafed not to
