shaken vigorously. This was continued for ten or twelve 
hours. The percentage obtained was 3°17, or if reduced to the 
amount for one hour, “about 0°32. 
zone Was passed through re alcohol, and the vapor 
condensed in a cool flask. Percentage 1°18, 
5. Ozone was passed through boiling alcohol in a flask pro- 
vided with a vertical condenser, by which the condensed liquid 
was returned to the flask, and me! repeatedly subjected to the 
action of the gas. Percentage 1°22. 
6. In the following series of Sepeunene alcohol was em- 
ployed which had been mixed with quick-lime, and after 
standing several days was then distilled off. It contained less 
than two per cent of water. Four determinations were made, 
with alcohol alone, and with alcohol mixed with different pro- 
ee of distilled water. The liquid was maintained at the 
oiling point during the whole operation, a vertical condenser 
being used, as in the Riis experiment. The results are 
water in the mixtures, the third shows the oo ercentage of 
acid obtained, the fourt h the amounts corres oat ng to equal 
portions of alcohol, and the fifth those amounts divided by 
four, giving the approximate absolute percenta 
numbers are reduced, to correspond toa pe of 
each experiment one hour.
