before any intumefcencc appeared in the milk,yet afterwards,wben the 
external Air was fully withdrawn, the white liquor began to boyle in a 
way that was not fo eafy to dekribe,as plcafant to behold : And this it 
did for a pretty while with fo much impetuofjty, that it threw up fevc- 
ral parts of itfelf oat of the wide mouthed Glafs that contained it (and 
could have contained as much more j though there were not above two 
or three ounces of the liquor. 
A yet greater difpofition to intumefcence we thought we obfervediti 
the (7/2//, which was but fuitable to the vifcofity of the Texture. 
A?'o^^',that the two foregoing Experiments were made with an Eye 
caft upon the inquiry , that I thought might be made Whether,and how 
far the deftrudive operation of our Enginupon the included Animal, 
might be imputed to this, that upon the withdrawing of the Air, befidcs 
tlie removal of what the Airs prefencc contributes to life,the little Bub- 
bles generated upon the abfencc of the Air in the Bloud,juyces,and foft 
parts of the Body, may by their Vaft number, and their confpiring di- 
llenfion, variouriy ftreightcn in fome places, and ftretch in others, the 
Ve{lels,cfpeciaIJy the fmaller oncs,that convey the Bloud and Nourifti- 
ment •, and lo by choaking up fome paffages, and vitiating the figure of 
others, difturb or hinder the due circulation of the Bloud? Not to 
mention the pains that fuch diftenlions may caufc in fome l^Jerves, and 
membranous parts, which by irritating fome of them into Convulfions 
may haften the death of Animals, and dcftroy them fooner by occafion of 
thit irritation, than they would bedeftroyed by the bare abfence or lofs 
of what the Air is necefl'ary to fupply them with. And to fliew, how this 
produdion of Bubbles reaches even to very minute parts of the Body, 
Ifhalladd.on this occafion (hoping that I have not prevented my f elf 
on any other,)what may feem fomewhat ftrange,what I once obferved in 
a Viper ^(iiriouily tortured in our Exhaufted Receiver, namely that it -had 
manifeftly a confpicuous Bubble moving to and fro in the waterifh hu- 
mour of one of its Eyes. 
Another Digreffive Exferiment belonging to the fame T'itle, 
To Oiew,that nof only the Bloud and Liquors,but alfo the other Soft 
parts, even in cold Animals, have Aerial particles latitant in them ^ 
we took the LjV^-r/ and Heart of ari Eele^ as alfo the Head and Bo- 
dy of another filh of the fame kind, cut a funder crofle wayes fomewhat 
beneath the heart,and putting them into a Receiver, upon the withdraw- 
ing of the Air we perceived^ that the Liver did manifeftly fwell , every 
way,and that both the upper and lower parts did fo likewife ^ and at the 
place where the divifion had been made,there came out in each portion 
of the fifh divers Bubbles, fcveral of which feemed to come from the 
Medulla Spnalis^at the cavity of the Back- bone, or the adjoyning parts ^ 
and the External Air being let in,both the portions of the Eelc prefent- 
ly (lirunkjfome of the skin fecming to be grown empty or flaccid in each 
<pf them.
