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

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

 on ihe 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 mollified, was 

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

 francs from the Paris Academy.
