nstead of running in the general directions of the
limbs, will, for the most part, run _across_ the twigs. But, if we draw
our lines from the outer extremities of the branches and twigs up to the
root, or near to the source of the trunk, we will find the lines, in the
main, running nearly parallel with the branches. Now, let us substitute
for this inverted tree the nervous system of a man, and remember that
the electric current moves from the positive to the negative pole as
nearly in straight lines as it can where there are good conductors, such
as the nerves and muscles, and it will at once appear that, in treating
the lower limbs, if we place our N. P. at the coccyx, and then
manipulate with P. P. over the feet and legs, our electric lines are
running from all the surface extremities of the nerve ramifications,
wherever the P. P. is moving, directly into and along these fine
ramifications, and, through the larger nerve-branches, up to the
stationary N. P. Or, if we treat the _trunk_ of the body by placing the
N. P. on the spine, near its upper end, and then manipulate with P. P.
from the lower part upward over the back, sides, abdomen and chest, our
current strikes into the surface extremities of the nerves at every
point where the electrode touches, and makes its way upwards, along the
nerve-lines, to the great spinal cord under the N. P.--thus replenishing
with fresh electricity all the ganglions, plexuses and nerve-trunks
along the way. But if P. P. be made stationary at the lower end of the
section under treatment, and we manipulate over the parts with the N.
P., the current strikes from P. P., across the nerve branches and comes
out at their surface extremities wherever the negative electrode
moves--so reaching but indirectly and imperfectly the trunk-lines and
their centers.

COMMON COLDS.

Take the B D Faradaic current--moderate strength. If the affection be
mainly in the head, give,

_1st._ _A face bath._ Let an earthen wash-basin, nearly filled with
tepid water, be placed on a table or chair before the patient, he
holding the sponge-roll [see page 89] N. P. in his hands. Now let him
bury his face in the water as long as he can hold his breath. At the
instant after his face is in the water, drop into the water the tin
electrode P. P. Repeat this process as often as he recovers his breath,
some eight, ten or a dozen times.

_2d._ Place the sponge-roll N. P. in the hands as before, and, making an
