          was indeed to go to Phila [Philadelphia] in order to
repeat some of my experiments on Elect
on a larger scale with the machine or
battery of Dr Hane - The Dr was very
kind and I was fortunate enough to
produce come interesting results

I found that by sending a discharge
from 32 gallon jars through a
copper wire 80 feet long 1/10 of an
inch in diameter that currents were
produced on every side of it to
such an extent that needles
could be magnetized at [blotched: the?]
distance of 12 feet. What is
also very remarkable these current
changes their direction with different
distances and where discharges of
different intensities are passed
through the wire - I will
write you more at length soon
My love to the little ones and
respects to Mrs. Torrey

In haste yours

Joseph Henry
Dr Torrey
