almoft half full of water, we put into it^ at the Orifice ( which Was 
pf etty largq) si (mM Gudgeon ^ about three Inches long , which 
when it was in the\Water fwam nimbly up and down therein. 
TJhen having draw^i out the Air fo well , that we gueis'd by a 
Ga'ge,,that about nineteen parts of twenty or more might be ex- 
hauftedj we fecur'd our felves^ that the regrefs of the Air fhould 
not injure our Experiment 5 about which we obferv'd thefe par- 
ticulars* 
Firjl^ The neck of the Glafsbeing very long , though there 
appeared great ftore pf Bubbles all about the Fillip yet the reft 
of the Water ^ notwithftanding the withdrawing of fo much 
Air as has been mention'd^ emitted no froth ^ and but few Bub- 
bles* 
Secondly^ The Fifh both at his mouth and gills did 5 for a 
great while^ dilcharge fuch a quantity of Bubbles as appeared 
ftrange, and for about half an hour or more ( for much longer 
I had not opportunity to watch it^) when ever he refted a whiie, 
new Bubbles would adhere to many parts of his Body (as if they 
were generated there) efpecially his Fins rsod Tayle ; So that he 
would appear almoft befet with Bubbles \ aod if, being excited 
to fwim, he was made to fhake them off^ he would quickly , up- 
on a little Reftjbe befet with new ones as before. 
Jhirdly^ Almoft all the vvhile he would gape and move his 
GillSj as before he was included ; though towards the end of the 
time that I watch d^ it often happened, • that he neither took in, 
nor emitted any Aerial particles that I could perceive. 
Fourthly^ Mttr a while he lay almoft conftantly with his Belly 
upwards^ and yet would in that pofture fwim brifkly as be- 
fore. 
Fifthly^ Nay after a while he feem'd to be more lively than at 
firft putting in 5 whether by reafon, that by difcharge of fo ma- 
ny Bubbles , which by their diftenfion perhaps put him to pain, 
he found himfelf relievd 3 or for fome other caufe^ I examine 
not/ , : 
Having occafion to go abroad, I returned about an hour and 
a half after he had been feaFd upland foond him almoft free from 
Bubbles, and with his Belly upwards, and feembg fomewhaj; tu- 
midj but yet lively as before. But an hour aod a quarter afccr 
that, when rifingirom dinner I went to look upon him again, 
he feerr/d to be movelefs aod fomewhat ftiff 3 yet upon ihakiog
