all other refpeds, it feemed as little altered as it 
'would have been, had the bottles, which contained 
it, been all the while well clofed with corks. 
§2. In order more fully to afcertain the fadts above 
mentioned, I filled two of thofe long vials, in which 
Frontiniac wine is ufually kept, and two common 
quart bottles, with the Pouhon water, and fitted to 
them bladders in manner before related ; excepting 
that the necks of the bladders were foaked in water, 
in order that they might better adhere to the glafsthan 
they did when moiftened with oil. The water, thus 
excluded from any communication with the external 
air, flood feven days in a room, where it was conti- 
nually kept lukewarm ; the weather at that time be- 
ing excefiively hot, the mercury then ufually {land- 
ing from 8 o to 85 degrees in Fahrenheit’s Thermo- 
meter. During all that time, the bladders were not 
diflended by wny elaflic fubflance arifing from the 
water thus heated, but remained as empty as when 
tied to the veffels. The water in the two quart bot- 
tles, being examined after it had thus flood leven days, 
was clear, retained its brifk and fharp tafle, and 
feemed in no wife decompounded ; but, when 
poured into a glafs, fparkled much, like wine on the 
fret. After a third part of the water was poured 
from one of thofe bottles, it was imriiediately clofed 
with the hand, and fliaken brifkly about for half a 
minute j and being then fuddenly opened, the air 
mflaed out of it with an explofive noife, and more 
than ordinary violence, driving the water with great 
force, and difperfing it over the floor in a fliower of 
leven yards in diameter.
