Geographical Distribution Of Disease.

Considerable attention has been paid, with
in the last thirty years, to The origin and eau.
ses OF diseases. The statistics collected on
this subject have established fact long sus.
pected by the medical profession, which 10,

epidemics. Mr. Keith johnson, in late
work, has gathered together many curious
facts pertinent 10 this problem. The plague,
for example has never appeared in the New
World, nor in the Southern hemisphere, and
