The Reverend Doctor Lardner was a pushful person who knew how to make use of the knowledge-hunger of his time, 

 and impressed Thackeray as a literary quack who advertised his cyclopaedia at dinner-parties. He followed up his 

 elopement with a lecturing tour in the United States and Cuba which brought him in 40,000., and then settled in 1'aris. 



He was a man of great and versatile ability, master of a lucid style, and as a populariser of science did excellent 

 work.' D. N. B.

This still valuable work contains in a collected form all the author's important discoveries and investigations (e.g. 

 on the electric arc, simultaneously with Sir Humphry Davy, polarized electricity, his theory of diamagnetic phenomena, 

 etc. etc.). De la Rive was one of the founders of the electro-chemical theory of galvanism, which, slightly modified, was 

 accepted by Faraday ; he was also the inventor of the first gold-plating process, for which he received a prize of 3000 

 francs from the Paris Academy.
