comes from the dccom position Of the agate cup.
Thus would nny one have said, and ordinary

nor have any results been more important. He
took small quantity of potash and placed upon
platinum spa,ua or Disc. He wished now to
transmit the electric current through it, and for
that purpose placed the positive wire AZ one side
and the negative At the other, expecting that its
elements would yield to the opposite force and be
decomposcd.


But in It's dry state it would not pass, nor
could the current be transmitted unless aids
could be procured to assist It's conducting power
Inc nrst suggestion was 10 dissolve 1t in the water
He did this and submitted the solution to the
ton of tie Notaic pile; ba; he found that this
most hayward agent had preferences. just a- bodc,
had axes OF preference aruund whics alone they
would r,vc,:. The electricity would sclhe upon
