Prof. Kekule was one of the founders of Ihe 'structure theory' (on which the above work is based), whose greatest 

 triumph was the discovery of the constitution of the ' aromatic compounds ' by Kekule himself, but which shortly 

 afterwards had to give way to Frankland's theory of valency. 



' By his Lelirhxich der organischen ChemU, in which he endeavoured to work out the typical view and subsequently 

 the structural doctrine to their logical conclusions, he had exercised an immense influence on the chemists of his time.' — 

 I'rof. E. V. Meyer.
