6. that is, I suppose, the cold
periods, and consequent exacerbations of fever, in this malignant
scarlatina, occur twice in a lunar day; which is about ten minutes less
than 25 hours; so that if the commencement of one cold fit be marked, the
commencement of the next may be expected, if not disturbed by the
exhibition of wine or opium, or the application of blisters, to occur in
about twelve hours and a half from the commencement of the former; or if
not prevented by large doses of the bark.

No one could do an act more beneficial to society, or glorious to himself,
than by teaching mankind how to inoculate this fatal disease; and thus to
deprive it of its malignity. Matter might be taken from the ulcers in the
throat, which would probably convey the contagion. Or warm water might be
put on the eruption, and scraped off again by the edge of a lancet. These
experiments could be attended with no danger, and should be tried for the
public benefit, and the honour of medical science.

12. _Miliaria._ Miliary fever. An eruption produced by the warmth, and more
particularly by the stimulus of the points of the wool in flannel or
blankets applied to the skin, has been frequently observed; which, by cool
dress, and bed-clothes without flannel, has soon ceased. See Class I. 1. 2.
3. This, which maybe called _miliaria sudatoria_, has been confounded with
other miliary fevers, and has made the existence of the latter doubted. Two
kinds of eruptions I have seen formerly attended with fever, but did not
sufficiently mark their progress, which I conceived to be miliary
eruptions, one with arterial strength, or with sensitive irritated fever,
and the other with arterial debility, or with sensitive inirritated fever.

In the former of these, or _miliaria irritata_, the eruptions were distinct
and larger than the small-pox, and the fever was not subdued without two or
three venesections, and repeated cathartics with calomel.

The latter, or _miliaria inirritata_, was attended with great arterial
debility; and during the course of the fever pellucid points appeared
within the skin, particularly on the soft parts of the fingers. And, in one
patient, whom I esteemed near her end, I well recollect to have observed
round pellucid globules, like what are often seen on vines in hot-houses,
no larger than the smallest pins' heads, adhere to her neck and bosom;
which were hard to the touch, but were easily rubbed off. These diseases,
