A while after we put in a Mouſe, new
ly taken, in ſuch a Trap as had rather af
frighted then hurt him; vvhil'ſt he vvas
leaping up very high in the Receiver, vve
faſten'd the Cover to it, expecting that
an Animal uſed to live in narrow holes
vvith very little freſh Air, vvould endure
the vvant of it better then the lately men
tion'd Birds: But though, for a vvhile af
ter the Pump vvas ſet avvork, he conti
nued leaping up as before; yet 'tvvas not
long ere he began to appear ſick and gid
dy, and to ſtagger, after vvhich he fell
dovvn as dead, but vvithout ſuch violent
Convulſions as the Birds died vvith.
Whereupon, haſtily turning the Key, we
let in ſome freſh Air upon him, by vvhich
he recovered, after a vvhile, his ſenſes and
his feet, but ſeem'd to continue vveak and
ſick: But at length, grovving able to
skip as formerly, the Pump vvas plyed
again for eight minutes, about the mid
dle of vvhich ſpace, if not before, a very
little Air by a miſchance got in at the
Stop-cock; and about tvvo minutes after
that, the Mouſe divers times leap'd up
