was covered with black india-riibber tubing, so that the flat polished 

 terminal disks only were exposed to the action of the electrolyte. The 

 bars used for the magnets were of polished steel, 4 \ inches long, 

 T 5 -g inch diameter, cut adjacently, previous to magnetisation, from a 

 longer bar. A pair of magnets were securely placed in the wooden 

 frame W, and the N". and S. terminals of each bar immersed in the 

 solution placed below. A number of experiments were made with 

 the arrangement, fig. 6, and with a galvanometer in circuit, using a 

 pair of new steel magnets each time. In these observations the 

 current appeared to flow from the N. to the S. polar terminal ; care 

 was exercised to ensure that the magnets were as near as practicable 

 equally magnetised. 



The results of these preliminary observations are recorded in 

 Table E.
