ling off, venesection should be immediately
used; which prevents the danger of consumption. At this time also change of
air is of material consequence, and often removes the cough like a charm,
as mentioned in a similar situation at the end of the chin-cough.

_Rubeola inirritata._ Measles with inirritated fever, or with weak pulse,
has been spoken of by some writers. See London Med. Observ. Vol. IV. Art.
XI. It has also been said to have been attended with sore throat. Edinb.
Essays, Vol. V. Art. II. Could the scarlet fever have been mistaken for the
measles? or might one of them have succeeded the other, as in the measles
and small-pox mentioned in Sect. XXXIII. 2. 9.?

From what has been said, it is probable that inoculation might disarm the
measles as much as the small-pox, by preventing the catarrh, and frequent
pulmonary inflammation, which attends this disease; both of which are
probably the consequence of the immediate application of the contagious
miasmata to these membranes. Some attempts have been made, but a difficulty
seems to arise in giving the disease; the blood, I conjecture, would not
infect, nor the tears; perhaps the mucous discharge from the nostrils might
succeed; or a drop of warm water put on the eruptions, and scraped off
again with the edge of a lancet; or if the branny scales were collected,
and moistened with a little warm water? Further experiments on this subject
would be worthy the public attention.

11. _Scarlatina mitis._ The scarlet fever exists with all degrees of
virulence, from a flea-bite to the plague. The infectious material of this
disease, like that of the small-pox, I suppose to be diffused, not
dissolved, in the air; on which account I suspect, that it requires a much
nearer approach to the sick, for a well person to receive the infection,
than in the measles; the contagion of which I believe to be more volatile,
or diffusible in the atmosphere. But as the contagious miasmata of
small-pox and scarlet fever are supposed to be more fixed, they may remain
for a longer time in clothes or furniture; as a thread dipped in variolous
matter has given the disease by inoculation after having been exposed many
days to the air, and after having been kept many months in a phial. This
also accounts for the slow or sporadic progress of the scarlet fever, as it
infects others at but a very small distance from the sick; and does not
produce a quantity of pus-like matter, like the small-pox, wh
