obtained possessed strongly the peculiar ozone odor. It was now pass- 
ed over copper (obtained by decomposing the oxide by carbonic oxidé,) 
heated to redness, “ water was immediately formed as in _ — ext 
periment. > 
In subsequent dipesituedi, the ozonized oxygen sebitaiaap dried, 
was passed through a glass tube heated to redness, by which the pe- 
culiar odor was completely destroyed ; to this an accurately weighed 
chloride of calcium tube was fixed, after the gas had been passed a 
short time, the tube was found to have increased perceptibly in weight. 
_ When the ozonized oxygen is passed through water, it communicates 
toitthe peculiar odor. If this solution is added to a mixture of starch 
paste and iodide of potassium, a blue color is produced; and when 
mixed with ferro-cyanide of potassium, this salt gives a blue precipitate 
with proto-salts of iron. Solutions of lime and baryta give, with a solu- 
tion of ozone, a heavy and’apparently crystalline precipitate. 
- Mr. Williamson states as the result of his experiments, that ozone is 
hot produced by the action of air on phosphorus, but we cannot admit 
- this; for'several reasons. The results of M. Marignac were obtained 
the substance’ formed in this manner, and many of the results ob- | 
tained by him are precisely the same with those of Mr. Williamson ; 
and these as we as others omen — be referred to the action “4

Such as completely to defeat the object in view ; for although ozone is 
generated by the action of phosphorus on ‘air, yet it is itself absorbed or 
osed, when brought in contact with a large surface of phospho- 
Tus ; and this result would especially occur when the phosphorus was 
heated, as it must have been from the exposure of so large a surface. 
own observations also have shown that something distinct from . : 
phosphoric or phosphorous acids, is generated by this process, for after — 
the air enclosed in the globe had been thoroughly agitated and allowed 
to stand some hours, in contact with a mixture of carbonate of lime and 
water, it still retained the peculiar odor, and the aeope decompo-

The conclusion which these gentlemen deduced from ‘their experi- 
ments was, that the substance which presents these curious reactions is 
@ compound of oxygen and hydrogen, containing more oxygen than 
water, and perhaps isomeric with the deutoxide of Thenard. This 
view was certainly consonant with their results, and indeed they appear- 
ed to be inexplicable by any other hypothesis. The oxidation of silver 
to such a degree, and the conversion of iodide of potassium into iodate 
of potassa, evince the existence of oxygen in a feebly combined and
