In cases OF paralysis mora than any others,

Paralysis occurs whenever the motor nerves are
separated from the nervous centres by any in
impairing their senativeness. With destroyed
nerve, paralysis is incurable, but in case Of it's
disease only, it's functions almost always be-
restored by electric treatment. As there is
always some degree of muscular atrophy in the
case, electricity is directed upon the nerves and
tho muscles at onco, and the battery aud tho in-
duction current usually employed together. As
q rule, tho first modites tho general nutrition,
and restores nervous ezcitability, while the last
stimulates tho contracti1e power Of the muscu-
lar Gbrcs.
