ration was ended and the Receiver taken off, the Frog was per-

ijear an hour, though the Abdomen was very mnchy and the throat 
fomewhat extended 5 this latter part having alfo left that wonted 
panting motion, that is ftppofed to argue and accompany the 
i refpiration of Frogs. At the end of about hours ^ after the re- 
moval of the Receiver from the pump, the Air was let in 5» where- 
upon the Abdomen^ which by that time was ftrangly fwelled, did 
not only fubfide, but feemed to have a great cavity in it , as the 
throat alio proportionably had 5 which cavityes continued , the 
Frog being gone paft all recovery.

^ A large Frog was conveyed into a plated Receiver 3 
and the Air being withdrawn, her body by degrees was 
diftendcd 5 as appeared very notably, when by a cafual fpringing 
of a leak, the Air got in again, and made'her look much more 
lank and hollow than ever. The Receiver with the Gage were 
kept underwater near feven hours5becaufc I was obliged to ftay 
long abroad 5 at the end of which coming home I found the Re- 
ecivcr ftaunch, but the Frog dead and exceedingly fwelled: up- 
on the letting in of the Air , (he became more hollow and lank 
than ever*
