remedy, its ill
effects being sometimes the production of a nettlerash or some mild
form of joint pains. In small doses, it will prevent the occurrence of
diphtheria in those exposed, or liable to exposure, to the disease.
The proper dose and method of employing antitoxin it is impossible to
impart in a book of this kind. Paralysis of throat, of vocal cords, or
of arms or legs--partial or entire--is a frequent sequel of
diphtheria. It is not caused by antitoxin.

The points which it is desirable for everyone to know are, that any
sore throat--with only a single white spot on the tonsil--may be
diphtheria, but that when the white spot or deposit not only covers
the tonsil or tonsils (see Tonsilitis) but creeps up on to the
surrounding parts, as the palate (the soft curtain which shuts off
the back of the roof of mouth from the throat), the uvula (the little
body hanging from the middle of the palate in the back of the mouth),
and the bands on either side of the back of the mouth at its junction
with the throat, then the case is probably one of diphtheria. But it
is often a day or two before the white deposit forms, the throat at
first being simply reddened. The fever in diphtheria is usually not
high (often not over 100 deg. to 102 deg. F.), and the headache, backache, and
pains in the limbs are not so marked as in tonsilitis.

=MEMBRANOUS CROUP.=--Membranous croup is diphtheria of the lower part
of the throat (larynx), in the region of the Adam's apple. If in a
case of what appears to be ordinary croup (p. 83) the symptoms are not
soon relieved by treatment, or if any membrane is coughed up, or if,
on inspection of the throat, it is possible to see any evidence of
white spots or membrane, then a physician's services are imperative.

It is not very uncommon for patients with mild forms of diphtheria to
walk about and attend to their usual duties and, if children, to go to
school, and in that inviting field to spread the disease. These cases
may present a white spot on one tonsil, or in other cases have what
looks to be an ordinary sore throat with a simple redness of the
mucous membrane. Sore throats in persons who have been in any way
exposed to diphtheria, and especially sore throats in children under
such circumstances, should always be subjected to microscopical
examination in the way we have alluded to before, for the safety of
both the patient and the public.

There is still another point perhaps not generall
