332 Meissner’s Researches on Oxygen, Ozone, and Antozone, 
apparatus into prolonged action, (six hours daily for eight days) 
passing the stream of electrized air first, through strong solution 
I, then through concentrated potash lye, and lastly a 
three vessels of water. When this experiment was finished, th 
water of the receivers reacted very powerfully on KI. It was 
concentrated by evaporation, in which process it finally acquired 
an acid reaction, first reddening and afterward bleaching litmus 
paper. A crystalline residue remained which when dissolved in 
water and treated with SO, gave a copious separation of iodine. 
Other reactions confirmed this substance as 10,. On further 
experiment it was found that so soon as the atmizone .current 
was deprived of its mozsture it was no longer capable of trans- 
porting IO,. It would therefore appear that when iodine is set 
free in the solution of KI by the action of the ozone occupying 
the periphery of the air bubble, a portion of it, vaporizing im 
wardly, is there oxydized by ozone to IO, and then is taken up 
by the atmizone cloud, and by it transmitted through the varl- 
ous solutions. 
In the next place Meissner examined the deportment of Schén- 
bein’s antozone to water vapor, to ascertain whether it possessed 
the cloud-forming property. By experiments with the gas 
evolved from BaO, and HO, SO,, this was found to be the 7 
and the antozone cloud resembled, in all particulars, that yie! 
by atmizone. If, for example, a tube containing the just mixed 
materials for giving off antozone is carried into a flask occupied 
with moist air, the latter gradually becomes filled with a cloud 
which disappears again after a short interval. 
_ Another point to investigate was the deportment of antozoné 
toward solution of KI. Schénbein asserted that antozone de- 
composes this salt and oxydizes its elements, while atmizone 
appears to be unaffected by it. On repeating Schdnbein’s exper 
iment, and further investigating the subject, Meissner conc 
that the reaction observed by Schdnbein was due to the sul- 
phuric acid of the mixture being mechanically projected against 
the test papers. At least, when solution of KI was placed in 
vessel beside the tube evolving antozone, no iodine was liber® 
ted in the former until after the addition of FeO, SO,. peel 
bein himself has lately expressed the probability that antozoné 
does not decompose KI. i 
In one further particular, there is a difference between attr 
zone and antozone which Meissner was unable to account 
satisfactorily. Antozone hasa peculiar odor, and when 51 of 
exeites a choking sensation, while atmizone manifests neither ‘ 
ed from 
sub- 
in all other respects must warrant the conclusion that the tw? 
are essentially identical.
