A. W. Wright— Oxidation of Alcohol and Ether. 185 
tended series of experiments was made by the writer, the re- 
sults of some of which are here given 
used, both absolute, and mixed with varying quantities of 
water. The ozone was produced by passing dry oxygen 
through an ozonizing tube under the influence of electricity. 
In some of the experiments Houzeau’s apparatus for this pur- 
pose was employed ; in others that described by the writer in a 
former number of this Journal, used with statical electricity. 
All the connections of the parts of the apparatus traversed by 
means of a solution of caustic potash in distilled water, and 
the percentages given in the results express the Bey pda of 
acid obtained relatively to commercial acetic acid, with which 
the comparisons were made. As the latter contains about 25 
per cent of anhydrous acid, a sufficiently near approximation 
to the absolute percentage of acetic acid would be obtained by 
dividing the results by four. In all cases the amounts obtained 
were very small. Commercial alcohol, which contained about 
85 per cent of water, was used in the experiments numbered 
1to5. The volume of liquid used in each case was 100 cubic 
centimeters, 
1. In this experiment vapor of alcohol was passed into a 
flask kept at 100° C., by means of a water-bath, and ozonized 
oxygen driven slowly through the same flask. The mixture of 
gas and vapor was then conducted into another flask immers 
2. Ozone and alcohol vapor were passed through a porcelain 
re of 260° or 250° C. Percentage 
obtained 0-81, of which but a portion was acetic acid, as the 
3. small quantity of alcohol was placed in a large flask, 
and ozone punt into tt at intervals, the flask being frequently
