children from it abates the inflammation, and thus affords relief. _It
is always well to leave one vesicle undisturbed_.

52. _If the infant have any "breaking out" upon the skin, ought that
to be a reason for deferring the vaccination_?

It should, as two skin diseases cannot well go on together; hence the
cow-pox might not take, or, if it did, might not have its proper
effect in preventing small-pox. "It is essential that the vaccine bud
or germ have a congenial soil, uncontaminated by another poison,
which, like a weed, might choke its healthy growth."--_Dendy_. The
moment the skin be free from the breaking-out, he must be
vaccinated. A trifling skin affection, like red gum, unless it be
severe, ought not, at the proper age to prevent vaccination. If
small-pox be rife in the neighbourhood, the child _must_ be
vaccinated, regardless of any "breaking-out" on the skin.

53. _Does vaccination make a child poorly_?

At about the fifth day after vaccination, and for three or four days,
he is generally a little feverish; the mouth is slightly hot, and he
delights to have the nipple in his mouth. He does not rest so well at
night; he is rather cross and irritable; and, sometimes, has a slight
bowel-complaint. The arm, about the ninth or tenth day, is usually
much inflamed--that is to say it is, for an inch or two or more around
the vesicles, red, hot, swollen, and continues in this state for a day
or two, at the end of which time the inflammation gradually
subsides. It might be well to state that the above slight symptoms are
desirable, as it proves that the vaccination has had a proper effect
on his system, and that, consequently, he is more likely to be
