20 Meissner’s Researches on Oxygen, Ozone, and Antozone. 
In water which h en traversed by the air from moist 
phosphorus, previously deozonized by means of KI, no nitrous 
i no ammonia could be detected. Of the latter, at least 
only those minute traces everywhere recognizable with potassio- 
iodid of mercury, were observed. 
The water, thus containing HO, but free from NO, and NH,, 
contained PO,. When the antozone cloud produced by phos- 
phorus is received in a perfectly dry and clean vessel, and there 
allowed to resolve into ordinary oxygen and water, the latter, 
which deposits as a dew on the walls of the vessel, has an acid 
reaction, which is not attributable to the minute trace of 10, it 
contains, but proceeds from PO,, whose presence is readily made 
out by the usual tests. 
which accounts for the finding of PO, and PO, by other ob- 
servers. It is of course only needful to procure sufficient con- 
tact between the antozone cloud and water, or an alkali, to arrest 
these substances entirely. 
When the air clouded by contact with moist phosphorus is 
made to pass direct through water for a long time, the latter 
uires an acid reaction from PO,, After the PO, is removed, 
or neutralized, HO, may be detected by aid of KI, starch and 
FeOSO,. Nitric acid Meissner found but very rarely and then 
in but very minute traces.’ It appears that while in electrized 
air nitrogen is oxydized by the ozone to a considerable extent, 
in air streaming over phosphorus the phosphorus appropriates 
the ozone in great measure. 
_ The results of the mutual action of phosphorus, air, and water 
are somewhat different, when, asin Schénbein’s experiments, the 
air is allowed to stagnate over the phosphorus. In the phos- 
: pee ecid, as we may designate the solution which forms about 
the phosphorus in the ordinary ozone bottle, there are found
