ez : 1 put no water in the tube, but fet the 
end of it in the ciftern of water x. Three 
hours after 1 found the water fucked up in 
the tube many inches to ^ 5 which (hews, 
that a confidcrable quantity of air was im- 
bibed by the branch, out of the tube r i e z: 
And in like manner did the Apricock-

well clofed up with melted cement. 
I then drew the air out of the receiver,
