ten give our faces and hands. Suppofmg then that, if I could get fomc 
thefe,and include thcm,being of thofe Infers they call AcjnatUia.dind fo 
minute as they are, they may live a great while in the Receiver without 
Air,and in the mean while attain the Period, which, according to na- 
tures courfe,is wont to turn thera^into flyes, which might come forth 
winged Creatures into a Medium not furnifhed with common Air, as 
thers of their kind enjoy ^ fuppofing, I fay, that thefe Infeds would af- 
' ford me fome information about thefe particulars, having upon much 
watching met with four or five of them after a fhower of Rain , thae 
dropt from a houfe into a veffel laid on purpofe for it, wc included 
them with fome of their water into afmall Giafs Receiver, which being 
very exadly clofed,we kept in a South- window, where thefe little Crea- 
tures continued to fwim up and down for fome few dayes without feem* 
ing to be much incommodated by fo unufual an habitation and at the 
end of that time, and much about the fame day, they dcvefled the habit 
they had5whileft they lived as flfhes/and appeared with their Exuvlst or 
caft coats under their feet,ftiewing themfel ves to be perfed Gmts^ that 
ftood without finking upon the furface of the water, and difcovered 
therafelves to be alive by their motion, when they were excited to it ^ 
but I could not perceive them to fly in that thin medium ^ to which ina- 
bility, whether the vifcolity of the water might contribute, I know not-, 
though they lived a pretty while, till hunger or cold deftroyed them. 
Some thing in this Experiment may deferve ferious Refledions j which 
I cannot fpare time to offer at, 
A Digrej]ive Experiment concerning the Expanjton of Blond and other Anl» 
mal Juyces, 
For fome purpofes, relating partly to Refpiration, and partly to o- 
ther Enquiries,! thought fit to endeavour to obtain what information 
could be procured, of the Confidence and Difpofition to expand it felf 
of and other Animal Liquors In purfuance of which theenfuing 
tryals, among others^ were undertaken. 
The warm Blood of a Lamb or a Sheep being taken as it was haftily 
brought from the Butchers , where the Fibers had been broken to hinder 
the coagulation, was in a wide mouth'd Glafs put into a Receiver, made 
ready for it and the pump being early fet on work, the Air was dili- 
gently drawn out but the Operation was not aiwaies,efpecially at firf] ^ 
fo early manifeft,as the Spirituoufnefs of the Liquor made fome exped - 
yet this hindered not but after a long expedation,the more fubtle parts 
of the Blood would begin to force their way through the more clammy 
ones, and feem to boyle in large clufters, fome as big as great Beans or 
Nutraeggs ^ and feraetimes, to the wonder of the by-ftanding PhyHti- 
ans, the Blood was fo Volatile, and the expanfion fo vehement, that 1t 
boyled over the containing Glafs of which, when it was put in.it did 
not.by our eftiraate, fill above a quarter. , Having alfo included fome 
Milk, warm from the Cow in a Cylindrical vcflcl of about four or five 
inches high, though the Operator were induced to pump a great while
