Meissner’s Researches on Oxygen, Ozone, and Antozone. 333 
The author now goes on to give the results of his observa- 
tions on the deportment of the mixture of ozone and antozone 
as obtained by the electrization of pure oxygen. He finds that 
ozone does not prevent the union of HO with antozone, with 
production of HO,. When instead of pure oxygen, common air 
is electrized the nitrogen of the latter becomes involved in the 
reactions, and in water through which the electrized mixture is 
passed, nitric acid gradually accumutates, but chiefly in the first 
water-receiver. When the electrized air has become charged 
with moisture, the production of NO,, (as well as that of HO, 
which is simultaneously formed,) is lessened to an extraordinary 
egree, 
- Schénbein’s statements regarding the generation of NH,O, NO. 
made it necessary to look for this salt in the electrized air. 
' Meissner affirms tiat NO, cannot be safely distinguished from 
O, by means of KI and starch, for no decided difference in the 
amount of iodid separated by addition of an acid or of FeO, 
SO, can be perceived. Nitrous acid must therefore be detected 
in some other manner when, as in the case before us, it is mixed 
with HO,. When nitrates are treated with dilute sulphuric acid, 
NO, is liberated and by contact with FeO, SO,, is reduced with 
‘0,. In fact we should not expect to find NO, under these 
circumstances, as the excess of ozone would oxydize any that 
might at first appear. Ammonia could not be detected by Ness- 
ler’s extraordinaril y delicate test. ; 
~ On passing electrized oxygen first through a receiver of water 
and then, in a second receiver, bringing it in contact with nitro- 
gen (common air), it resulted that no NO, could be detected in 
the water of the first vessel, while in that of the second, it was 
Teadily found though in smaller quantity than in the previous 
€xperiments. It was thus demonstrated that the oxydation of 
‘is not, or is not alone, a direct result of electrical action, but 
1s the effect of the excited oxygen.
