either as in young
children fixed attention cannot be roused, or as in severe cases the
effort only adds to the child's nervousness, and in consequence
increases the movements, they must be given up. All drill and gymnastics
are best carried out in class with other children, and regulated not
simply by word of mouth, but by a tune or chant. When recovery is in
progress gymnastics will then in almost all instances find their place.

Even when drill and gymnastics cannot be practised, regulated movements
of the limbs carried out twice a day for ten minutes at a time are of
very real service. Another's will here takes the place of that of the
patient, and the limbs are thus taught, though far more imperfectly, to
act in concert.

Two or three more cautions may still be of service. Do not keep a child
out of bed, and force it to try to exert itself when the movements are
very severe; continued movement, voluntary or involuntary, fatigues. Let
the child lie in bed; it rests there, and the movements, which always
cease during sleep, become at once greatly lessened. So important indeed
is it to avoid the exhaustion caused by incessant violent movement, that
in bad cases it is sometimes necessary to swathe the limbs in flannel
bandages, and so to confine them to splints in order to restrain them.
Next, do not become over-anxious because the child grows stupid and
ceases to talk; intelligence and the power of speech will certainly come
back again. And, lastly, do not be impatient and think your medical
adviser incompetent because the disorder lasts so long. An average
duration of seventy days implies that while sometimes it ceases sooner,
in others it lasts much longer than the two weary months of watching and
waiting with which in any case you must lay your account.

=Paralysis, or Palsy.=--When speaking of St. Vitus's dance I said that
there was a partial loss of power in the limbs as well as an inability
to control their movements. After a fit of convulsions, or an epileptic
seizure, power over some limb is often lost for a time which may vary
from a few minutes to some hours. In the course of some serious diseases
of the brain, one of the manifestations of the mischief is the
impairment or the loss of power over one arm or leg, rarely over both;
and lastly, that terrible disease diphtheria is often followed by a
paralysis so general that the patient is sometimes for days unable to
move even a finger, although the conditio
