much more liable to sunstroke than others. This is on account of the
poisonous effects of the alcohol upon the nerves. No doctor would think
of giving alcohol in any form to a man suffering with sunstroke.

~33. Effects of Alcohol upon the Tissues.~--Here are two interesting
experiments which your teacher or parents can make for you.

_Experiment 1._ Place a piece of tender beefsteak in a saucer and cover
it with alcohol. Put it away over night. In the morning the beefsteak
will be found to be shrunken, dried, and almost as tough as a piece of
leather. This shows the effect of alcohol upon the tissues, which are
essentially like those of lower animals.

_Experiment 2._ Break an egg into a half glassful of alcohol. Stir the
egg and alcohol together for a few minutes. Soon you will see that the
egg begins to harden and look just as though it had been boiled.

~34.~ This is the effect of strong alcohol. The alcohol of alcoholic
drinks has water and other things mixed with it, so that it does not act
so quickly nor so severely as pure alcohol; but the effect is
essentially the same in character. It is partly in this way that the
brain, nerves, muscles, and other tissues of drinking men and women
become diseased.

Eminent physicians tell us that a large share of the unfortunate persons
who are shut up in insane asylums are brought there by alcohol. Is it
not a dreadful thing that one's mind should be thus ruined by a useless
and harmful practice?
