its proper use in nutrition. Thus, step by step, the use of alcoholics
impairs the functions of the blood corpuscles, perverts nutrition, and
slowly poisons the blood.

[NOTE. "Destroy or paralyze the inhibitory nerve center, and instantly
its controlling effect on the heart mechanism is lost, and the
accelerating agent, being no longer under its normal restraint, runs
riot. The heart's action is increased, the pulse is quickened, an
excess of blood is forced into the vessels, and from their becoming
engorged and dilated the face gets flushed, all the usual concomitants
of a general engorgement of the circulation being the result."--Dr.
George Harley, F.R.S., an eminent English medical author.

"The habitual use of alcohol produces a deleterious influence upon the
whole economy. The digestive powers are weakened, the appetite is
impaired, and the muscular system is enfeebled. The blood is
impoverished, and nutrition is imperfect and disordered, as shown by
the flabbiness of the skin and muscles, emaciation, or an abnormal
accumulation of fat."--Dr. Austin Flint, Senior, formerly Professor of
the Practice of Medicine in Bellevue Medical College, and author of
many standard medical works.

"The immoderate use of the strong kind of tobacco, which soldiers
affect, is often very injurious to them, especially to very young
soldiers. It renders them nervous and shaky, gives rise to
palpitation, and is a factor in the production of the irritable or

digestion."--London _Lancet_.

"I never smoke because I have seen the most efficient proofs of the
injurious effects of tobacco on the nervous system."--Dr.
Brown-Sequard, the eminent French physiologist.

"Tobacco, and especially cigarettes, being a depressant upon the
heart, should be positively forbidden."--Dr. J. M. Keating, on

Children_.]

201. Effect of Tobacco upon the Heart. While tobacco poisons more or
less almost every organ of the body, it is upon the heart that it
works its most serious wrong. Upon this most important organ its
destructive effect is to depress and paralyze. Especially does t
