e laws. In short, I mean living
_according to_ nature. Probably a large proportion of the diseases to
which human life is subject, are the natural consequence of living
_contrary to_ nature; or contravening the great laws which govern our
present mode of existence.

Within the compass of a single letter, I cannot be very particular on
this subject. But I would recommend to you to read approved writers on
_health_, and the structure and constitution of the human body. Try to
understand the _principles_ upon which this truly wonderful machine is
kept in motion. You will find it a most interesting subject. You will
see the evidence of a mighty intellect in its construction. You will
also be able to draw from it practical lessons to guide you in the most
common concerns of life. I am the more earnest in this recommendation,
because I think you will discover that many of those habits and customs
of society, which are peculiarly under the control of ladies, need
reforming. I am seriously of the opinion that the general health of
society depends far more upon the _ladies_ than upon the _physicians_.
The former direct the preparation of the daily supplies of food,
designed to sustain, refresh, and keep in motion the human system. The
latter can only give prescriptions for regulating this delicate
machinery, when, by mismanagement, it has got out of order. I will,
however, give you a few simple rules for the preservation of health,
which, though incomplete, will be of great benefit, if faithfully
pursued. From experience, study, and observation, you will no doubt be
able to add to them many improvements.

1. _Make attention to health a matter of conscience, as a religious
duty._ Pray daily that God would give you wisdom and self-denial, that
you may be able to avoid whatever is injurious, and to persevere in the
judicious use of such means as are necessary to promote sound health
and energy of body.

2. _Maintain habitual cheerfulness and tranquillity of mind._ Few
persons are aware of the influence which this has upon the health of the
body. If you are subject to _melancholy_, avoid it, and fight against it
as a _sin_, dishonoring to God, and destructive of your own health and
happiness. It is dishonoring to God, because it is calculated to give
the world a gloomy and repulsive idea of religion. Nor is this view of
the subject at all inconsistent with the exercise of sorrow for sin, and
feeling for sinners. Godly sorrow is a
