The figures as well as the curves show that the condensation 

 rises very rapidly at first and then gradually attains a maximum^ 

 when the composition of the mixture corresponds nearly to the 

 formula CH^Og + SHgO, from whence on they gradually fall ta 

 the zero value of no condensation. 



Acetic Acid. 

 Determinations made at 22° C. 

 The boiling point of the acetic acid was 118.1° corrected. 



The following are the results obtained by Von Reiss :
