Effect on the Organs of Special Sense.--Professor Forel, one of the
foremost European experts on the question of the effect of alcohol on the
nervous system, says: "Through all parts of nervous activity from the
innervation of the muscles and the simplest sensation to the highest
activity of the soul the paralyzing effect of alcohol can be demonstrated."
Several experimenters of undoubted ability have noted the paralyzing effect
of alcohol even in small doses. By the use of delicate instruments of
precision, Ridge tested the effect of alcohol on the senses of smell,
vision, and muscular sense of weight. He found that two drams of absolute
alcohol produced a positive decrease in the sensitiveness of the nerves of
feeling, that so small a quantity as one half dram of absolute alcohol
diminished the power of vision and the muscular sense of weight. Kraepelin
and Kurz by experiment determined that the acuteness of the special senses
of sight, hearing, touch, taste, and smell was diminished by an ounce of
alcohol, the power of vision being lost to one third of its extent and a
similar effect being produced on the other special senses. Other
investigators have reached like conclusions. There is no doubt but that
alcohol, even in small quantities, renders the organs of sense less
sensitive and therefore less accurate.

Effect of Alcohol on the Ability to Resist Disease.--Among certain classes
of people the belief exists that alcohol in the form of brandy or some
other drink or in patent medicines, malt tonics, and the like is of great
importance in building up the body so as to resist disease or to cure it
after disease has attacked it. Nothing is further from the truth. In
experiments on a large number of animals, including dogs, rabbits, guinea
pigs, fowls, and pigeons, Laitenen, of the University of Helsingsfors,
found that alcohol, without exception, made these animals more susceptible
to disease than were the controls.
One of the most serious effects of alcohol is the lowered resistance of the
body to disease. It has been proved that a much larger proportion of hard
drinkers die from infectious or contagious diseases than from special
diseased conditions due to the direct action of alcohol on the organs of
the body. This lowered resistance is shown in increased liability to
contract disease and increased severity of the disease. We have already
alluded to the findings of insurance companies with reference to the length
of life--the abstainers from alcohol have a much better chance of a longer
life and much less likelihood of infection by disease germs.
