1have made the tryal with a Butter-fly, if
the cold Seaſon would have permitted us
to finde any. The Fly, af
ter ſome Exſuctions of the
Air, dropp'd down from the
ſide of the Glaſs whereon ſhe
was walking: But, that the
Experiment with the Bee
might be the more inſtructive,
we convey'd in with her a bun
dle of Flowers, which re
main'd ſuſpended by a ſtring
near the upper part of the Receiver: And
having provok'd the Bee, we excited her
to flie up and down the capacity of the
Veſſel, till at length, as we deſir'd, ſhe
lighted upon the Flowers; whereupon
we preſently began to draw out the Air,
and obſerv'd, That though for ſome time
the Bee ſeem'd to take no notice of it, yet
within awhile after ſhe did not flie, but fall
down from rhe Flowers, without appear
ing to make any uſe of her Wings to help
her ſelf. But whether this fall of the Bee,
and the other Inſect, proceeded from the
mediums being too thin for them to flie in,
or barely from the weakneſs, and as it were
ſwooning of the Animals themſelves, you
will eaſily gather from the following Ex
periment.
