Table I gives the constants calculated from values recorded in the 

 literature^ for acids other than the volatile fatty acids. Table TI gives the 

 data for the latter acids. 



Table I.

»i-Toluic, . . 0'40 jj-Hydroxy benzoic, very small 



The acids, glycollic, monochloracetic, oxalic, malonic, mandelic, and 

 phenylacetic, have small distillation constants. " Nitroglycerine" is also dis- 

 tillable in steam, and its distillation constants are now being determined.
