d in this state throws it suddenly upon the brain.
The powerful shock propels it instantly to the exterior surface, and
torrent-like contracts it back again in redoubled fury upon the brain,
and leaves the countenance pale and ghastly. It deranges in a great
measure the mind, and unfits it for useful action. It darts its
electric fire of vengeance along the optic nerve, expands the retina,
and gives to every object a magnified and false appearance, while the
very eye-balls by a wild and savage glare proclaim the dreadful storm
that is raging within, and pouring the poisonous streams of premature
death through all the healthful channels of existence! It suddenly
braces the nervous system, and then on the opposite extreme leaves it
depressed and weakened. It gradually brings on rheumatic complaints,
and lays the whole system open to the most formidable and painful
disorders that afflict the human race. It cannot have escaped medical
observation that fevers and consumptions are much more frequent among
persons who are very irritable and exercise little or no rule over
their passions, than among those who are of a mild temperament, either
naturally, or from early restraint and education.

There is a connexion between the mind and the body so subtle that it
has hitherto eluded the eagle-eye of Physiology, and will perhaps
remain inscrutible forever to human comprehension. But that this
connexion exists is fully demonstrated by medical experience, and
observation. Many bodily disorders derange the mind, and have in many
instances totally destroyed it. So on the other hand diseases of the
mind effect the body in return, and _grief, despair_ and _melancholy_
have so preyed upon the vitals as to emaciate the body, and bring it
to the grave. It is not uncommon that consumptions are brought on by
_trouble_ of mind, by _guilt_, and by _melancholy_ and _grief_. And
many instances have occurred, where persons in excessive violent anger
have dropped down dead. What is so dreadful, when carried to extreme,
must be very injurious to health, and long life, when indulged
frequently and even moderately.

There being then such an intimate connexion between the mind and body,
and so many thousands of ways in which one alternately acts upon, and
effects the other, and brings millions to an untimely grave, we see at
once the propriety of not only guarding our health by temperance in
eating and drinking, but more particularly by avoiding troub
