ON the 3d of November laft, Sir James Hall and Dr Ru* 

 therford afked me to repeat with them fome experi- 

 ments on what has been called Animal Electricity, which were 

 firft performed by Dr Galvani, Profeifor of Anatomy at Bo- 

 logna, and of which an account had been communicated by- 

 Mr Seguin of Paris to Dr Black, in a letter dated Paris, 

 3d Auguft. 



We accordingly, with the help of my afliftant Mr FiTFE, re- 

 peated them in the following manner : 



We cut a living frog into two parts, a little above the lower 

 end of the fpinal marrow. We then put the middle part of a 

 bit of tinfoil, about one-tenth of an inch in breadth, and two 

 inches long, under the beginning of one of the fciatic nerves, 

 and then doubled the tinfoil over the nerve, that is, we in- 

 cluded the nerve in the doubling of the tinfoil. We next 

 placed one half-crown filver piece between the table and loins 

 of the frog, and another between the table and its leg. We 

 then bended a piece of brafs-wire, about the fize of a common 



flocking-
