* The disk was below standard size both in diameter and in thickness. 



Table II contains the results obtained with copper. The 

 disks were cut from a good quality of commercial sheet copper 

 of -the same diameter (40 mm ) as the gold mercury disk, but 

 were slightly thinner at the outset, and during the experiment 

 of course became still thinner, though the diminution of sur-
