In a letter which we have received from profefTor Pi«Slet, 

 ofGi^neva, we are informed that, bcfides the golden medal 

 voted to profeObr Volta by the National Inltituie, the French 

 government has rewarded him for his difcovery refpecling 

 gaivanifm with a prefent of 6000 franco. A tew days after 

 his arrival at Lyons, he received the following letter from, 

 the niinifter of the interior : 



" The French government, citizen profefTor, has granted 

 to you a prefent of 6000 francs (250 1. (lerling). It has 

 thought this mark of elieem due to the illuftrious philofopher 

 who, after enrichins; fcience with ufeful truths for twenty- 

 five years, has come to depofit in the Inilitute the fecret of 

 nature and of the effetls of gaivanifm. [ am happy in being 

 thcorgan of gox'ernment to a man whom I tfteem, and for 

 whom I have long entertained an affection. I beg you to 

 accept the friendfliip of the confuls. I fakile you cordially.
