has been traced between the origin of a cholera epidemic, and the
arrival of an individual from an infected to a previously healthy
neighborhood, that there should be no doubt as to the spread of the
disease by human intercourse. This point may be considered as so

assumption of a grave responsibility. The evidence which is
advanced against the contagiousness of cholera does not weaken the
accumulated force of the facts in its favor, some of which do not
admit of a reasonable doubt, but it only shows that the liability
to contagion is diminished, or strengthened, by certain localizing
causes. Preconceived opinions, although honestly taken, have been
in many instances an obstacle to the belief in the communicability
of cholera from individual to individual, and the same result has
been produced in others from a failure to appreciate the indirect
manner in which the disease is believed, on good evidence, to be
communicated. The other methods supposed to account for the exten
