Theory of Molecular Volumes, 465 



The constitutive effect which we have named the Volume 

 Anomaly is thus seen to be clearly defined by the above table. 

 This may be illustrated in detail as follows : —

Nitrobenzene. Methyl Salicylate, C 8 H 8 3 . 



The latter compound may be shown to have its formula 

 justified thus —
