Obfervations and Experiments on the Galvanic Power. By a Correfpondent, 



To Mr. NICHOLSON. 

 SIR, ^ Edinburgh. 



X. HE readinefs with which you admitted a former communication of mine (notwith- 

 ftanding that its deficiencies muft have been apparent to your acutencfs, and that there are 

 now feveral parts of it which later experiments would induce me to correft or explain), has 

 encouraged me to lay before you fome phenomena that I have obferved.in the interefting 

 fcience of Galvanifm. 



I began my inquiries on that fubjeft almoft immediately after the firft publication of the 

 account of Signor Volta's Pile in your Journal, in concert with a friend, who, to the ex- 

 perience of years, added all the ardour of youth in the purfuit of fcience, but whofe life 

 was ftiortened by an unfortunate accident in a vigorous old age : I premife this account of 

 my own experiments, by refcuing from oblivion the itw obfervations that his time and 

 health would allow him to make ; and which will come with no fmall intereft to the world, 

 when it is known they were thofe of the intimate friend of a Franklin and of a Black.
