ordinary electricity. Shocks are obtained from these ; the screening 

 influence of good conductors is shown to take place; magnetism is 

 developed ; and the alternations in the direction are found to exist as 

 in the currents from galvanic induction. Some remarkable results 

 are given in reference to the great distance at which the induction 

 takes place. Experiments are detailed in which needles were made 

 magnetic, when the conductors were removed to the distance of 

 twelve feet from each other. 



Prof. Henry made a verbal communication, during the course 

 of which he illustrated, experimentally, the phenomena deve- 

 loped in his paper.
