Stohmann and Lansbein - sive the following tabulated results 



In comparing the chemical behaviour of these series it -will perhaps be 

 best to consider a fe-w typical reagents and briefly discuss their action. 

 Generally speaking, ho-wever, the properties of hydro-aromatic substances 

 are the same as those of aliphatic bodies as modified by the presence of 

 a- ring and -well illustrated by the hydrophthalic acids (p. 130).
