- Meissner’s Researches on Oxygen, Ozone, and Antozone. 331 
antozone or the product of its action on water, viz: HO,, is pres- 
ent, and that besides, there exists in both a substance which like 
ferrous sulphate “ disposes” HO, to act upon KI, since they de- 
compose KI without the addition of FeO, SO,. 
Returning to the question of the identity of atmizone and ant- 
ozone, Meissner informs us that a liquid having the reactions 
of HO, is obtained when a current of electrized air is passed for 
some hours through a strong and alkaline solution of pyrogallie 
acid, (which deprives it completely of ozone), and subsequently 
through pure water. The water slowly acquires a recognizable 
content of HO, giving with KI and starch no reaction until the 
addition of FeO, SO,, when an instantaneous liberation of I be- 
comes manifest. Atmizone, however, appears capable of oxyd- 
izing water only when it is newly formed. If the stream of 
electrized and deozonized air is passed through a series of ves- 
sels containing water, HO, scarcely appears in the second and 
subsequent vessels, though the atmizone cloud is formed in them 
all. This cloud, however, is the less dense and well defined, the 
farther from the induction apparatus it is produced, and it ma 
ence be inferred that atmizone loses its power of oxydizing 
HO when its electrical polarity has declined beyond a certain

. No substance having the properties in question could be imag- 
Med present save iodic acid which is known to liberate I from 
Kl and which is likewise formed when ozone acts upon KI. 
But in what manner this body could pass out of one alkaline 
Solution and through another, as must be the case here, was diffi- 
ult to conceive. Meissner at once attempted to demonstrate 
directly its presence or absence. He therefore put his electrizing
