The production of a mixture of acetone and n-butyl alcohol on an industrial 

 scale by a fermentation process has rendered desirable a knowledge of the 

 system n-butyl alcohol-acetone-water. The literature fails to reveal any 

 previous work on this ternary mixture, although several density determina- 

 tions for both acetone and n-butyl alcohol have been recorded.
