PREFACE.


In introducing the following pages to the notice of the Public, it is
the Author's wish to exhibit in as clear a light as our present
researches on the subjects treated of will allow, the connexion between
one of the most terrific phænomena with which our globe is visited, and
a phænomenon which, although but little known, appears to be intimately
connected with revolving storms. How far he has succeeded, either in
this particular object or in endeavouring to render the essential
phænomena of storms familiar to the seaman, is left for the Public to
determine. Should any advantage be found to result from the study of the
Atmospheric Waves, as explained and recommended in this little work, or
the seaman be induced by its perusal to attend more closely to the
observations of those instruments that are calculated to warn him of his
danger, an object will be attained strikingly illustrative of the
Baconian aphorism, "Knowledge is Power."
