/^iiice the points in Figs. 4 and 5 lie so closely together, only through 
those for the largest initial amplitudes are curves drawn. However, the 
loci corresponding to the different initial amplitudes are indicated on the 
two figures, and the general relations of their -paths can readily be 
seen. 
In the progress of the last year’s work many other interesting phe- 
nomena concerning the wire have been observed, and the full results 
of the work have been published in a more technical journaF. However, 
it was thought that the above observations wmuld be of interest to the 
members of the Academy, and of value to students of physics.
