with water, but in the conditions of all the foregoing experi- 
ments, it enters combination by the action of ozone, as Schin- 
bein formetly maintained and was the first to suggest. Ozone 
is formed not only in all rapid combustions but also in the 
slow oxydation of organic matters (paper and linen.) 
Pincus has lately published some observations which any 
chemist may readily verify, that demonstrate the formation of 
ozone in combustion at high temperatures. It is only neces- 
sary to hold a cold, clean and dry beaker glass for a few seconds 
over a jet of pure hydrogen burning from a metal tube with 
a flame } of an inch high, and then to smell of its contents. 
The ozone odor is most plainly perceived. The same result 
may be obtained from a small flame of alcohol or of a stearme

strongly by the researches of Schénbein and Meissner, we must 
consider the case pretty well made out in theory, for hydte 
peroxyd which is held to be the result of the union of antozone 
with water, is formed in so many instances of slow oxydaion 
of metals and organic bodies that Schénbein felt justified m 
ming its production, or that of a corresponding organic 
antozonid in them all—<(Jour. fiir. prakt. Chem., xcvill and 
cix. 
In Schénbein’s experiments before mentioned, where pape 
or linen were not employed, the dust of the atmosphere pro 
ably supplied the organic matters. : | 
first result of the oxydation of nitrogen is nitrous acid | 
alone (at least Schénbein and Bohlig detected no nitric acid), 
when the combustion is complete as in case of hydrogen, % 
when organic matters are excluded from the experiment. Nit 
acid is a product of the subsequent oxydation of nitrous acid. 
Hen organic matters exist in the product of combustion, 25 
when alcohol burns in a heated apparatus yielding water bat 
ing a yellowish color, it is probable that nitrous acid is formed, 
but is afterward reduced to ammonia,
