he rest, and is gradually pushed out whole and undecayed; on its
rising up a pus-like mucus is seen discharged from the gum, which surrounds
it; and the gum seems to have left the tooth, as the fangs or roots of it
are in part naked.

M. M. Where the tooth is sound it can only be saved by evacuations by
venesection, and a cathartic; and after its operation two grains of opium,
a blister may also be used behind the ear, and ether applied to the cheek
externally. In slighter cases two grains of opium with or without as much
camphor may be held in the mouth, and suffered to dissolve near the
affected tooth, and be gradually swallowed. See Class I. 2. 4. 12.
Odontalgia may be distinguished from otitis by the application of cold
water to the affected tooth; for as the pain of common tooth-ach is owing
to torpor, whatever decreases stimulus adds to the torpor and consequent
pain; whereas the pain of an inflamed tooth being ceased by the increased
action of the membranes of it is in some measure alleviated by the
application of cold.

8. _Otitis._ Inflammation and consequent suppuration of some membranes of
the internal ear frequently occur in children, who sleep in cold rooms, or
near a cold wall, without a night-cap. If the bones are affected, they come
out in a long process of time, and the child remains deaf of that ear. But
in this case there is generally a fever attends this inflammation; and it
then belongs to another genus.

M. M. A warmer night-cap. Warmish water should be gently syringed into the
ear to keep it clean twice a day; and if it does not heal in a week, a
little spirit of wine should be added; first about a fourth part, and it
should be gradually increased to half rectified spirit and half water: if
it continues long to discharge matter with a very putrid smell, the bones
are injured, and will in time find their exit, during which time the ear
should be kept clean by filling it with a weaker mixture of spirit of wine
and water; or a solution of alum in water; which may be poured into the
ear, as the head is inclined, and shook out again by turning the head, two
or three times morning and evening. See Class II. 1. 4. 10.

9. _Fistula lacrymalis._ The lacrymal sack, with its puncta lacrymalia and
nasal duct, are liable to be destroyed by suppuration without fever; the
tears then run over the eyelids, and inflame the edges of them, and the
cheeks, by their perpetual moisture, and saline acrimony.
