les and scarlatina,
the person who sleeps in the patient's room is much more likely to
contract the disease than she who sits up and watches at night keeping
wide awake. Whoever takes charge of a fever patient during the night
should therefore sit up and watch, not lie down and doze, and this not
for the patient's sake only, but for her own.

It can scarcely be necessary to say that in every, even the mildest,
attack of typhoid fever the attendance of the doctor is needed from
first to last. He may come every day, and may daily do nothing but
merely watch. The disease will run its course, the greatest skill cannot
cut it short, though now and then instead of lasting for three or even
four weeks it comes to an end spontaneously in fourteen days. Skilled
watching is what the competent doctor gives. You would not despise or
underestimate the pilot's skill, who steered your barque through a
dangerous sea in smoothest water, because he knew each hidden rock or
unseen quicksand on which but for his guidance you might have made
shipwreck.

=Small-pox.=--At the present day, thanks to vaccination, and to
re-vaccination, _small-pox_ is rarely met with in the well-to-do classes
of society, though it is not yet a century ago since it found its
victims not only among the poor, but among the highest in the land. It
does, however, occur sometimes after vaccination, and sometimes, though
very rarely, an attack of small-pox fails to furnish an absolute
guarantee against the occurrence of a second.

Small-pox, unmodified by previous vaccination, sets in in the child with
violent sickness; vomiting, sometimes recurring frequently for
forty-eight hours, with much depression, or even stupor; in some
instances even actual convulsions, and fever; but neither with the
sore-throat of scarlatina, nor with the sneezing, cough, and running at
the nose of measles. At the end of from forty-eight to sixty hours, an
eruption of pimples appears on the face, forehead, forearms and wrists,
whence it extends to the body and the lower limbs. They are reddish in
colour, rather pointed in form, and at first scarcely raised above the
surface; so that the eruption looks at first like the very early
eruption of measles; though the tiny pimples felt as if beneath the skin
serve even then to distinguish the one disease from the other. In
another forty-eight hours the character of the pimples has changed into
that of little vesicles or pocks, depressed instead
