cises, not merely automatic, but purposeful and under thorough
control.

To accomplish this there are two methods.

The first, very easy of comprehension, is to lie down on one's back and
to breathe deeply with the mouth closed and the nostrils dilated.

As much air as can be held must be taken into the lungs, then the mouth
must be opened and the air must be allowed to escape gradually.

During this operation one should pay particular attention to expanding
the walls of the chest, while flattening the stomach.

About twenty deep respirations are required to accomplish the desired
effect.

Little by little the lungs will dilate and one will unconsciously
increase the length of the inspiration and the slowness with which the
air is expelled.

The second method consists in standing erect, with the head thrown
slightly back. The lungs should then be filled with air and one should
count mentally up to five or even ten before exhaling the air that has
been breathed in.

It is advisable that when exhaling one should utter a continuous hum,
which must be absolutely free from trembling when one has practised it
properly.

People who have practised this exercise have often stated that this
method of breathing has been of great help to them when much fatigued as
well as a first-class stimulus in moments when all their physical powers
were to be called into play.

A well-known college professor has assured us that every day, before
giving his lectures, he makes use of this exercise. He claims that he
has thus gained a freedom of breathing the good effects of which are
manifest in the facility with which he is able to give his lecture and
in his general feeling of ease. Rendered quite free from any suspicion
of nervousness, he feels that he is completely master of himself and in
a fit state of moral and physical health to employ the poise that is
essential to the man who has to instruct and to convince others.

Deep breathing has the further advantage of developing the lungs, of
strengthening them, and at the same time of making their ordinary
functioning more regular.

The man who practises this exercise will have much less propensity to
get out of breath. This will be a great assistance to those timid people
who are disconcerted by trifles and who, at the least little occurrence,
become so much affected by emotion that they experience a sensible
acceleration of the action of the heart.
