houghts of the constant care of a loving, Divine Saviour
for even the least of His children, must be encouraged. Work, which is
an intolerable burden when depressing thoughts are encouraged, will
become easy when these are removed. If you get the sufferer made
hopeful for time and for eternity too, you have half won the battle.

Again, in bodily matters, food or drink which is exciting must be given
up, or very sparingly used. Tea should only be taken weak, and _at
most_ twice a-day. Avoid long conversations, and especially discussions
and debates. Let the head be soaped (_see_ Head, Soaping) with soap
lather at night, and rub all over with hot vinegar and olive oil before
rising in the morning. Many a shaken nervous system will speedily
recover under such treatment. Take also _eight good hours_ for sleep,
and allow no ideas of business or work to intrude upon them. No more
valuable habit can be formed, by the healthy as well as by the nervous,
than this. The whole will should resolutely be bent to remove the
attention from every trying thought, when the hours of work are past,
and especially on retiring to rest. Always recollect that this _can_ be
_done_; assert mentally, or if necessary, audibly, that it shall. Do
not let initial failure disappoint you; persevere and a habit will be
formed. When the brain gets a fair rest in its hours of leisure, it is
usually equal to all demands in ordinary hours of work.

All brain workers, in their leisure hours should let the brain rest,
and if they must do something, let it be as diverse from their work,
and as easy on the thinking power as is possible. (_See_ Worry).

Nerves, Spinal.--The spinal cord is continuous with the back part of
the brain. It is a mass of nerve fibres, and from it branch off in
pairs, all the way down from the brain, the great nerves which move the
limbs and muscles of the body, and receive the impressions of sensation
for conveyance to the brain. It is permeated by numerous blood vessels,
which supply what is needed for the upkeep of the whole mass. When
these relax, and become overfilled with blood, we have congestion of
the spinal cord. This may often be easily remedied by cold cloths
applied over the spine, with fomentations to the feet if necessary
(_see_ Children's Healthy Growth; Fall; Paralysis; St. Vitus' Dance).
If, on the other hand, the vessels are contracted, or the blood supply
