sanitary code. If this were so, a formula for a city of health were
practically useless. The city would come without the special call for
it.

I think it probable the city would come in the manner described, but
how long it would be coming is hard to say, for whatever great results
have followed civilisation, the most that has occurred has been an
unexpected, unexplained, and therefore uncertain arrest of the spread
of the grand physical scourges of mankind. The phenomena have been
suppressed, but the root of not one of them has been touched. Still
in our midst are thousands of enfeebled human organisms which only are
comparable with the savage. Still are left amongst us the bases of all
the diseases that, up to the present hour, have afflicted humanity.

The existing calendar of diseases, studied in connection with the
classical history of the diseases written for us by the longest
unbroken line of authorities in the world of letters, shows, in
unmistakable language, that the imposition of every known malady of
man is coeval with every phase of his recorded life on the planet. No
malady, once originated, has ever actually died out; many remain as
potent as ever. That wasting fatal scourge, pulmonary consumption, is
the same in character as when Coelius Aurelianus gave it description.
The cancer of to-day is the cancer known to Paulus Eginæta. The Black
Death, though its name is gone, lingers in malignant typhus. The great

The dancing mania of the Middle Ages and the convulsionary epidemic
of Montmartre, subdued in their violence, are still to be seen in
some American communities, and even at this hour in the New Forest
of England. Small-pox, when the blessed protection of vaccination is
withdrawn, is the same virulent destroyer as it was when the Arabian
