ulcers have been supposed sometimes to ensue with
subaxillary abscesses. Add to this, that the making two punctures either on
the same, or one on each arm, secures the success of the operation in
respect to communicating the infection.

Thirdly, at the time of the fever or eruption the application of cool air
to those parts of the skin, which are too warm, or appear red, or are
covered with what is termed a rash, should be used freely, as well as
during the whole disease. And at the same time, if the feet or hands are
colder than natural, these should be covered with flannel. See Class IV. 2.

10. _Rubeola irritata, morbilli._ The measles commence with sneezing, red
eyes, dry hoarse cough, and is attended with sensitive irritated fever. On
the fourth day, or a little later, small thick eruptions appear, scarcely
eminent above the skin, and, after three days, changing into very small
branny scales.

As the contagious material of the small-pox may be supposed to be diffused
in the air like a fine dry powder, and mixing with the saliva in the mouth
to infect the tonsils in its passage to the stomach; so the contagious
material of the measles may be supposed to be more completely dissolved in
the air, and thus to impart its poison to the membrane of the nostrils,
which covers the sense of smell; whence a catarrh with sneezing ushers in
the fever; the termination of the nasal duct of the lacrymal sac is subject
to the same stimulus and inflammation, and affects by sympathy the lacrymal
glands, occasioning a great flow of tears. See Sect. XVI. 8. And the
redness of the eye and eyelids is produced in consequence of the tears
being in so great quantity, that the saline part of them is not entirely
reabsorbed. See Sect. XXIV. 2. 8.

The contagion of the measles, if it be taken a sufficient time before
inoculation, so that the eruption may commence before the variolous fever
comes on, stops the progress of the small-pox in the inoculated wound, and
delays it till the measle-fever has finished its career. See Sect. XXXIII.
2. 9.

The measles are usually attended with inflammatory fever with strong pulse,
and bear the lancet in every stage of the disease. In the early periods of
it, venesection renders the fever and cough less; and, if any symptoms of
peripneumony occur, is repeatedly necessary; and at the decline of the
disease, if a cough be left after the eruption has ceased, and the
subsequent branny scales are fal
