received through the cable from Newfoundland.

of be,wet 2i5 and statute miles from Nalentia but
the locality cannot be more accurately aseertalned

cable at Greenwich be carefully measured and tested
against my standard in order TO obtain the most cor
rect estimate of the distance of the fault Assuming,
however that il is 30 miles. and allowing - per cent
for slack il is possible that the Chief defect is 10 shall

proved by its forming voltaic element, which gives
rise TO continuous positive current from The copper
wire varying very little in tension.

The actual resistance Of the fault appears TO be at
least equal to ten miles OF the cable, but Is most prob
ably greater.
Taking il at its lowest resistance namely, 10 miles,
and assuming that Newfoundland is only using $50
cells Of Dapeis's battery, the strongest current
