deposited eleclrol)licaIly. It appeared that when'' the de|x>sit 

 was made from nitrate of bismuth the ]ihenomenon was as 

 marked as it is with cast plates of the metal, whereas when 

 deposited from the tartrate the phenomenon w;is either extremely 

 feeble or non-existent. The asymmetr)' of the phenomenon on 

 reversal of the magnetic field was ex^ilained by the author as 

 ilue to the inHuence exerted by the magnetic fielil on the electric 

 conductivity of the metal, i le further regarded the difference 

 in Ijchaviour of the metallic film as jirecipilated, on the one 

 hand, from the nitrate, and on the other, from the tartrate or 

 citrate, as due to the fact th.it in the case of the latter salts the 

 bismuth is mixe<l with carlHin, whereas in the case of the nitrate 

 the metal is deposited in a pure state.
