ble to have our physical sense of right and
wrong benumbed, it is so to have our moral sense benumbed also. Yet what
person of sense ever complained of too tender a conscience, or too
perfect a sense of right and wrong in morals?"

EXERCISE OF THE LUNGS.--Judicious exercise of the lungs, in the opinion
of that eminent physiologist, Dr. Andrew Combe, is one of the most
efficacious means which can be employed for promoting their development
and warding off their diseases. In this respect the organs of
respiration closely resemble the muscles and all other organized parts.
They are made to be used, and if they are left in habitual inactivity,
their strength and health are unavoidably impaired; while, if their
exercise be ill-timed or excessive, disease will as certainly follow.

The lungs may be exercised _directly_ by the use of the voice in
speaking, reading aloud, or singing, and _indirectly_ by such kinds of
bodily or muscular exertion as require quicker and deeper breathing. In
general, both ought to be conjoined. But where the chief object is to
improve the lungs, those kinds which have a tendency to expand the chest
and call the organs of respiration into play ought to be especially
preferred. Rowing a boat, fencing, quoits, shuttlecock, the proper use
of skipping the rope, dumb-bells, and gymnastics are of this
description, and have been recommended for this purpose. All of them
employ actively the muscles of the chest and trunk, and excite the
lungs themselves to freer and fuller expansion. Climbing up a hill is,
for the same reason, an exercise of high utility in giving tone and
freedom to the pulmonary functions. Where, either from hereditary
predisposition or accidental causes, the chest is unusually weak, every
effort should be made, from infancy upward, to favor the growth and
strength of the lungs, by the habitual use of such of these exercises as
can most easily be practiced. The earlier they are resorted to, and the
more steadily they are pursued, the more certainly will their beneficial
results be experienced.

If the _direct_ exercise of the lungs in practicing deep inspiration,
speaking, reading aloud, and singing, is properly managed and persevered
in, particularly before the frame has become consolidated, it will exert
a very beneficial influence in expanding the chest, and giving tone and
imparting health to the important organs contained in it. As a
preventive measure, Dr. Clark, in his treatise o
