 de Rouen, 8vo. sewn (RARE), 15* 1784 



This work has the merit of being one of the first to treat soberly the subject of electro-therapeutics at a time when 

 electricity was thought to be a panacea for every known disease, and when generally far more harm (referred to on p. 100 ; 

 than good was done by the, electrical enthusiasts.

Though now chiefly known as one of the most hideous monsters of the Terror, and as the author of L'jtmi du Peuple, 

 the revolutionary journal, Marat was previously the author of works of no small scientific value. He was one of the first 

 to attack Newton's emission theoiy of light a heresy which prevented his election to the French Academy. He 

 translated Newton's Optlcks into French (q. v. post). 



The above work gives the author's own theory a curious variety of the corpuscular one.

This, like the rest of the author's works, is full of original ideas and experiments. Pp. 345-53 contain an interesting 

 chapter, 'Des Phenomenes electriques relatifs a 1'Ebranlement de la Lumiere,' in which he attempts an explanation of the 

 phenomena.

In this work the author attempts to give, by his theory of a fluide igne, a mechanical explanation of the phenomena 

 of heat. 



Marat stayed many years in England, and some time, as a teacher of French, in Edinburgh, where he published in 1774 

 a revolutionary pamphlet ' The Chains of Slavery.' On the recommendation of certain Edinburgh physicians he received 

 the degree of M.D. from St. Andrews University. According to Chambers's Encyclopaedia, he was already dying of 'a 

 loathsome skin disease ', contracted while hiding in the sewers of Paris from Lalayette's police, when he received his 

 death-blow from Charlotte Corday. The last two works contain the Privilege from Louis XVI. to his ' bien ame, le 

 sieur Marat ', who afterwards was the most ruthless promoter of his murder. 



All his scientific works are now VERY RARE.
