Experiment VI. 
The float B being continued in immerfion in fait 
water for 72 hours, it had loft 26 grains more of 
\ 0 ce, lofin^ in the fiift 48 hours 24, and 
in the 24 fucceeding hours two grains only j from 
which it appears, that, after the cork has been in the 
water for 48 hours, its abfbrption becomes lefs than 
before, in proportion as 12 isto i. 
This float having continued in the water for 78 
hours, each piece of cork, being wiped very drv on 
its furface, but not fqueezed, weighed as follows j

Being then deftrous to know if any quantity of
