The bees wax in my own experiments was well 
freed from honey, by the boyiing it in water, which 
probably made it lighter than it was fet down in 
Mr. Cotes’ s Table: and the fecond experiment 
which I made two years after the fir ft, if the dif- 
ference was not owing to the difference of hear, 
is an inftance of what I take to be a pretty ge- 
neral truth, that bodies become more denfe and 
compaft by red, and that they would alfo be found 
heavier in the fcale, in thofe cales where they do not 
lofe weight by the evaporation of humidity. 
The weights of vegetable Gums nearly correfpond 
with thofe of the ligneous parts.
