feet have been
cold; till on covering them with warm flannel, as the feet have become
warm, the face has cooled. See Sect. XXXV. 1. 3. Class II. 1. 3. 5. IV. 2.

M. M. Evacuations, abstinence, oil externally on the nose, warm diluent
fluids, warm shoes, warm night-cap.

8. _Expectoratio calida._ Warm expectoration consists of the increased
secretion of mucus from the membrane, which lines the bronchiae, or
air-cells of the lungs, without inflammation. This increased mucus is
ejected by the action of coughing, and is called a cold, and resembles the
catarrh of the preceding article; with which it is frequently combined.

M. M. Inhale the steam of warm water, evacuations, warm bath, afterwards
opium, sorbentia.

9. _Exsudatio pone aures._ A discharge behind the ears. This chiefly
affects children, and is a morbid secretion; as appears from its fetor; for
if it was owing to defect of absorption, it would be saline, and not fetid;
if a morbid action has continued a considerable time, it should not be
stopped too suddenly; since in that case some other morbid action is liable
to succeed in its stead. Thus children are believed to have had cholics, or
even convulsions, consequent to the too sudden healing of these morbid
effusions behind their ears. The rationale of this is to be explained from
a medical fact, which I have frequently observed; and that is, that a
blister on the back greatly strengthens the power of digestion, and removes
the heart-burn in adults, and green stools in children. The stimulus of the
blister produces sensation in the vessels of the skin; with this additional
sensorial power these vessels act more strongly; and with these the vessels
of the internal membranes of the stomach and bowels act with greater energy
from their direct sympathy with them. Now the acrid discharge behind the
ears of children produces sensation on that part of the skin, and so far
acts as a small blister. When this is suddenly stopped, a debility of the
digestive power of the stomach succeeds from the want of this accustomed
stimulus, with flatulency, green stools, gripes, and sometimes consequent
convulsions. See Class II. 1. 5. 6. and II. 1. 4. 6.

M. M. If the matter be absorbed, and produces swelling of the lymphatics of
the neck, it should be cured as soon as possible by dusting the part with
white lead, cerussa, in very fine powder; and to prevent any ill
consequence an issue should be kept for ab
