would, according to known laws, have a direction opposed to those of the

 carry out the assumption here made, M. "Weber is obliged to suppose that the 

 molecules of diamagnetic bodies are surrounded by channels, in which the in- 

 duced molecular currents, once excited, continue to flow without resistance." 1 

 "Diamagnetism and Magne-crystallic Action," pp. 136-187. 



1 In assuming these non-resisting channels M. "Weber, it must be admitted, 

 did not go beyond the assumptions of Ampere.
