though I would then wait no longer , yet three or four hours after ( vi^^, 
about lo of the Clock at night ) I returned to the Receiver, and found 
the lively enough. Whereupon 1 caufed the Giafs to be again 
cxhauClcd,and lecured from the Ingrcfs of the Air, during which time the 
Animal feemcd to be much difquieted by what was done to it-,, but did 
not loofe its motion before I went to bed, which was foon after. 
Experiment 6. 
About Bmterfliesl remember I made feveral Tryals , moft of which 
chanced to be loft but thus much 1 very well remember, that having 
obferved them not only to live but to move longer then was expeded, I 
chofe to include divers of them in Receivers fomewhat large, efpecially 
that I might fee,whether in fo thin a Medium fomc or other of them, by 
the help of their large wings, \vould be able to fly. But though, whilelt 
the Air continued in the Glafles, they flew adively as well as freely up 
and down • and though after the Exhauftion of the Air, they continued 
to live and were not movelefs ; nay though at the bottom of the Recei- 
ver they would even move their wings and a little flutter, yet I could 
not perceive any of them to fly, by which I mean, perform any progref- 
five motion fupported by the Medium only. And by frequently inverting 
the Receiver (which I took care fliould be pretty long to let them fall 
from one extream to the other, )they would fall like dead Animals with- 
out difplaying their wings though juft as they came to touch the Bot-- 
tora,fome of them would fometimes fcem to make fome ufeof them, but 
not enough to fuftain themfelves, or to keep their falls from being rude 
enough. 
The XX. Title. 
Of the neceffity of Air to the motion offuch fma/i Creatures^ ^ Ants and even 
Mites themfelves, 
in the Experiments hitherto mentioned ^the Animals ^on which the Tryals have 
been made yWere divers of them of a moderate Bnlk^-^ and others of them y though 
fma'l^yet not of theleaft fizzes that Nature afforded us. Wherefore I thought fit 
to annex the following Experiments, wherein I defigned to examine ^Whether even 
thofe minute forts of Animals^ whofe hulk^is thought the mo ft contemptible, have 
not^as well as the greater ^need of the Air^ if not to make them live , yet at leafi 
to enable them to move. 
A pretty number of were included in a fmall Portable Receiver 
exhaufted yefterday about noon ; Between 6 and 7 in the Afternoon 
they feemed to be all quite dead, and the rather,becaufe, though they were 
very lively juft before they were fealed up, running briskly up ana down 
the Bubble they were in yet they grew almoft movelefs as foon as the 
^ir was cxbauiled and a little while after appeared more f o : though 
1 then fufpeded more then 1 fmce did, that they were much inconveni- 
enced by ibme fmall glutinous fubftance that feemed to have got into 
the fmall Receiver from the Vapours of the Cement. When I looked on
