The following pages having already appeared in the form of letters
in the _Marylebone Mercury_, any preface on my part might be deemed
unnecessary. Having been repeatedly asked to collect and publish them,
I intended to revise if not rewrite the whole, but my professional
duties have deprived me of the time, so at once I place them in the
hands of my indulgent readers. This pamphlet does not pretend to be
a treatise on Hygiène, but simply to hint at some of the evils which
arise from the neglect of sanitary regulations, also to suggest some
simple remedies, and further to try and induce men to regard health as
one of the most valuable and sacred gifts of God.
