~9. Delirium Tremens.~ (De-lir´-i-um Tre´-mens.)--When a man takes
strong liquors regularly he very soon injures his brain and nerves so
that they do not get quiet, as they should, at night, and he does not
sleep well. He has frightful dreams. He sees all sorts of wild animals
and horrid shapes in his dreams. Perhaps you have sometimes had such
dreams from eating late suppers or indigestible food.

~10.~ Did you ever have a dream when you were awake? If a man drinks a
great deal he is likely to have a terrible disease known as _delirium
tremens_, in which he sees the same frightful things when he is wide
awake that he dreams about when he is asleep. This is one of the
terrible effects of alcohol upon the brain and nerves.

~11. Alcohol Paralysis.~--You have seen how a drunken man staggers when
he walks. Did you ever see a man who walked just as though he were drunk
when he was really sober? This is because a part of the brain or spinal
cord has been permanently injured or paralyzed. Alcohol is not the only
cause of this disease, and so you must not think every person who
staggers is or has been a drunkard; but alcohol is a very frequent cause
of paralysis.

~12. Effects of Alcohol upon the Mind and Character.~--When a man is
under the influence of alcohol is his character good or bad? Is a man
likely to be good, or to be bad, when he is drunk or excited by drink?
Most men behave badly when they are drunk, and after they have been
drunk a great many times they often behave badly all the time. A great
many of the men who are shut up in prisons would not have been sent
there if they had never learned to drink.
