The daa of one of his experiments are as follows. A flask, holding 
a litre, was filled with boiling water, then preiin & sealed with the 
eatest precaution, then inverted in a mercury trou en when the 
water is cold, it was opened under the mercury and half a litre of pure 
oxygen introduced. Immediately after was added to it, under the mer- 
cury, a small box of hay weighing 10 grams, which had just been raised, 
in a flask, by means of a stove to a temperature of 100° ©. and kept at 
this temperature for 30 minutes. The flask was then hermetically sealed 
by the aid of its stopper ground with emery; and to make it sure, when 
taken from the mercury a coat of varnish and vermilion was put over the 
aperture, 
Eight days afterward, small globules were found in the liquid and on
