A friend who called on me, to see the action of the apparatus, 

 observed, that if we should alter the position of the copper wire, 

 so as to enable us to bring a small needle between it and the 

 copper vessel, we should find that the under surface would either 

 attract or repel the needle, according to the position in which it 

 was held. Accordingly, on altering the apparatus, it was found 

 to answer what he anticipated. 



The above apparatus is well calculated to show the rotatory 

 motion, as there is no twisting or untwisting of a thread, which 

 will alter by the addition of weight or moisture.
