amounting to quite three drops; and, to my great furprife; I j 
found the piece frozen to the ice, fo as not to be eafily got off) — 
though all the ice employed was, at the PEGI of the ee | 
riment, in athawing ftate. 
I had prepared the apparatus bfak! taking the boiling hed as 
mercury; but being entirely difcouraged by thefe very unequal: 
refults, I gave that up, for the prefent at leaft, and : heating: 
the piece to 6° of my thermometer, turned it nimbly out of: 
the cafe in which it was heated into the cavity, throwing) 
fome fragments of ice over it. In about half an hour, I drew! 
off the water, which amounted to 11 pennyweights; then: 
ftopping the funnel again, and igi the covers, I left the’ 
whole about feven hours. 
At the end of that time, I found a confiderable. quantity of, 
water in the funnel: the melting of the ice had produced a — 
cavity between it and the fides, great part of the way down, 
which, as well as that in the middle, was nearly full. The 
water neverthelefs ran out fo flowly, that I apprehended fomes=: 
thing had ftopped the narrow end of the funnel, but the true; 
caufe became afterwards apparent upon examining the ftate of; 
the ice. The fragments which I had thrown over the thermo=; 
meter piece were frozen entirely together, and in fuch a form as - 
they could not have aflumed without frefh water fuperadded and 
frozen upon them, for the cavities between them were partly 
filled with new ice. I endeavoured to take the ice out with 
my fingers, but in vain; and it was with fome difficulty L 
could force it afunder even with a pointed knife, to gét at the, 
thermometer piece.: When that was got out, great- part of 
the’ coiled wire was found envelopéd in new ice. . The paflage 
through the ice to the ftem of the funnel, which I had made 
pretty wide with a.thick iron wireired-hot, was fo-nearly clofed
