health of our fellow-citizens from those unseen poisons which lurk
like wild beasts couched in the jungle, ready to spring at any
moment on the unsuspecting, the innocent, the helpless. Of all this
I longed to speak; but I thought it best only to hint at it, and
leave the question to your common sense and your humanity; taking
for granted that your minds, like the minds of all right-minded
Englishmen, have been of late painfully awakened to its importance.
It seemed to me almost an impertinence to say more in a city of
whose local circumstances I know little or nothing. As an old
sanitary reformer, practical, as well as theoretical, I am but too
well aware of the difficulties which beset any complete scheme of
drainage, especially in an ancient city like this; where men are
paying the penalty of their predecessors' ignorance; and dwelling,
whether they choose or not, over fifteen centuries of accumulated
dirt.

And, therefore, taking for granted that there is energy and
intellect enough in Winchester to conquer these difficulties in due
time, I go on to ask you to consider, for a time, a subject which is
growing more and more important and interesting, a subject the study
of which will do much towards raising the field naturalist from a
mere collector of specimens--as he was twenty years ago--to a
philosopher elucidating some of the grandest problems. I mean the
infant science of Bio-geology--the science which treats of the
distribution of plants and animals over the globe, and the cause of
that distribution.

I doubt not that there are many here who know far more about the
subject than I; who are far better read than I am in the works of
Forbes, Darwin, Wallace, Hooker, Moritz Wagner, and the other
