154 Count Romford* s Enquiry concerning the Nature of Heat, 
the spoon gradually changed its form, became less, and was at 
length evaporated : from being spherical and lucid, it gradually 
took an oblong form, and its surface became obscure; and, 
when it was evaporated, it left a kind of skin behind it, which 
was evidently composed of the particles of black matter, which 
had by degrees attached themselves to its surface, and which pro- 
bably had contributed not a little to its being at last heated, and 
evaporated. 
The change in the form of the drop of water, and more 
especially the gradual loss of its lucid appearance, made me 
suspect that it had turned round during the experiment. If it 
really did so, its motion must either have been extremely rapid, 
or very slow ; for, though I examined it with great attention, I 
could not perceive that it had any rotatory motion. 
I will take the liberty to mention another little experiment, 
which I have often made, to amuse myself and others, though 
it may perhaps be thought too trifling to deserve the attention 
of the Royal Society. 
Exper. No. 35. If a large drop of water be formed at the end 
of a small splinter of light wood, (deal, for instance,) and this 
drop be thrust quickly into the centre of the flame of a newly 
snuffed candle, which burns bright and clear, the drop of water 
will remain for a considerable time in the centre of the flame, 
and surrounded by it on every side, without being made to boil, 
or otherwise apparently affected by the heat ; and, if it be taken 
out of the flame, and put upon the hand, it will not be found to 
be scalding hot. 
If it be held for some time in the flame, it will be gradually 
diminished, by evaporation ; but there is much reason to think.
