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

 inducing magnet, and hence would produce the phenomena of repulsion. To 

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

 did not go beyond the assumptions of Ampere.
