We try'd alſo what Operation the
drawing out of the Air would have upon
Camphire, that being a Body, which,
though not a Liquor, conſiſts of ſuch
Volatile or Fugitive parts, that without
any greater agitation then that of the open
Air it ſelf, they will copiouſly flie away.
But we found not that even this looſe

IT may ſeem well worth trying, whether
or no in our exhauſted Glaſs the want
of an ambient Body, of the wonted thic
neſs of Air, would diſable even light and
little Animals, as Bees, and other winged
Inſects, to flie. But though we eaſily
foreſaw how difficult it would be to make
ſuch an Experiment; yet not to omit our
endeavors, we procur'd a large Fleſh-fly,
which we convey'd into a ſmall Receiver.
