ch altered or modified in its character. Indeed in children, in whom
of course vaccination has been but comparatively lately performed,
small-pox when it occurs will, in the majority of cases, be so mild
that the real nature of the disease will be with difficulty determined:
so mild, that again and again has a parent been heard to exclaim,
"Surely these few scattered pimples cannot be the small-pox!" If,
however, as the pimples progress, they are narrowly watched, and are
seen to become depressed in their centre; if there has been the
precursory rigor, etc.; and if the source of the disorder can be traced
to some case of undoubted small-pox, the child in fact having been
exposed to contagion, no doubt ought to exist in reference to the
nature of such a case, however slight may be the character of the
disease.

The usual progress, however, of small-pox modified by vaccination is
as follows. The first stage is the same usually as in the natural form
of the disease. As soon, however, as the eruption appears, the
modifying power of the vaccination becomes apparent. The eruption will
be found to be generally both less in quantity and more limited in its
extent; or if even it should come out profusely, and cover a large
extent of the surface of the body, still the controuling power of the
vaccination will immediately show itself after its appearance,--first,
in the complete subsidence of all the febrile symptoms which will now
take place; and, secondly, in reference to the eruption, part of which
will die away at once, and the remainder will by the fifth day be
filled with the opaque yellowish fluid, then dry up, becoming hard and
horny, and falling off will leave a mottled red appearance of the skin,
and now and then slight pitting.

Such is the usual progress of the disease: subsequent to vaccination,
it is a mild and tractable disorder. It is right, however, to mention
that small-pox has occurred even to the vaccinated in almost as severe
a form as the confluent natural small-pox, and running its regular
course unaltered or unmodified. Such instances, however, are extremely
rare, and form the exceptions to the general rule; for "no reasonable
doubt can be entertained, from the abundance of facts now before the
world, that such modification is the law of the animal economy, and
that the regular or natural progress is the exception."
