The maximum and ininiiniiin figures >ln.\v thai the oxidizing process carried out 

 under normal laboratory conditions is practically uniform with respect in tin- varying 

 amount- of fusel oil present. It was found that the reactions taking place Between 

 the liii hromateand the amyl alcohol were little understood, and that it was iuipossililc 

 to calculate a factor which gave anything like the actual results obtained; so that the 

 results of the experiments given above were made, and the surprising closeness of the 

 figures obtained by the various analysts shows that there is a definite reaction taking 

 place; and, while this reaction has not been figured out, the writers feel entirely justi- 

 fied by the results in adopting this factor. 



This change in the method was developed as it was found that the final distillation 

 of the volatile acids was not satisfactory, on account of the fact that only a portion is 

 distilled over when the present provisional method is followed. The following table 

 of experimental data develop* the conclusion just stated and shows on an average for 

 all contents of amyl alcohol that the percentage yield is raised from 7S to !)L' per cent
