Meissner’s Researches upon Electrized Oxygen. 213 
ArT. XXJ.—Abstract of the Second Series of Professor oo 
Researches upon Electrized Oxygen ;* by GEORGE F. BARKE 
the first series of Dr. Meissner’s researches upon oxygen, 
published in 1868—an abstract of which, by Professor John- 
son, appeared in this Journal, volume xxxvii, page 325, and 
volume XXXvVill, page 18—he arrived at the remarkable con- 
clusion, that oxygen, under the influence of electrical tension, 
was converted not only into ozone, but also into another modi- 
fication which always appeared simultaneously, and which form- 
ed, when brought into contact with watery vapor, acer 4 
after the absorption of the ozone, a peculiar dense 
second modification of oxygen Meissner identified with Schén- 
bein’s antozone. So remarkable were these results, and so im- 
portant their bearing, if true, not only upon our theories of 
ozone itself, but also upon the philosophy of chemistry, that 
Meissner desired to repeat his e Xperiments, studying ariel 
per now refe 
: a 
Section I is devoted to “Electrized Ox gen.” The experi- 
ment which is to be critically icon is thus described : 
‘Oxygen is submitted to the action of electricity in a Siemens’s 
or von Babo’s apparatus, is then passed into a receiver contain- 
forms above it a thick oe mist, which also appears in a less 
degree over the solution of potassium iodid, but which is den- 
ser, the less concentrated the solution and the more favorable 
the ozonizing conditions.” To prove that this mist consists 
solely of electrized oxygen and water, Meissner proposes to 
show :—Ist, that no per gas but oxygen is in any way con- 
cerned in the production of the phenomenon; particularly no 
nitrogen, chlorine, hydrogen, or carbonic acid. 2d, that for the 
production of the result, the presence of aqueous vapor in the 
electrizing tube is not necessary. And 3d, that the potassium 
iodid solution used for the absorption of the ozone, has nothing 
whatever to do with the appearance of the onan further 
than is implied in effecting the removal of the ozone from the 
current of electrized oxygen.
