it will be necessary to take away some Blood.
_Observ._ part III. ch. vii. sect. 5. Dr. _Lind_, in his
_second Paper on Fevers_, p. 66. says, "To all who are
supposed to be infected by Fevers, during this Stage of
Rigours, a gentle Vomit is immediately to be exhibited before
the Fever be formed, and before the Fulness or Hardness of
the Pulse renders its Operation dangerous. If the Vomit be
delayed too long, and especially if Bleeding must precede it,
the most certain and favourable Opportunity of procuring
Safety for the Patient is past.--That he has found it equally
serviceable in preventing Relapses, when it is given at the
Return of the Shiverings." A loose Stool, or two, should be
procured by the Emetic or Clysters, and he advises Sweating
immediately after, in the manner recommended by Dr.
_Pringle_. At other times "he gave five Grains of Camphire
every four Hours, with large Draughts of Vinegar-whey. Eight
Persons in ten, he says, got quite well by this Treatment."

I have never had sufficient Opportunities of trying this
Method of Prevention, to determine any thing certain about
it; but it may be worth while to practise it.

After Evacuations, if the Pulse kept up, we commonly gave nothing but
the saline Draughts, with the _Pulvis contrayervae_, or some temperate
Medicine, for the first Day or two. As soon as we could distinguish
the Fever to be of the malignant kind, and that the Pulse rather sunk,
we joined some of the Cordials to the saline Medicines, and allowed
the Patient more or less Wine, according to the Degree of the Fever.
Dr. _De Haen_ has found Fault with Dr. _Pringle_ and Dr. _Huxham_, for
administering cordial Medicines and Wine in the low State of this
Fever; but nothing answered so well with us as these Remedies under
such Circumstances; and I have frequently seen every Symptom changed
for the better by their Use; and even when I gave the Bark, in the
Manner recommended by _De Haen_, I often found it necessary to join
the free Use of Wine[9], Cordials and Blisters[10], in order to
support the Patient's Strength.

[9] _Petrus a Castro_, in his Account of a Petechial Fever,
which was frequent at _Verona_, tells us, that the Sick had a
great Thirst, and an Aversion to Meat, but all of them had
the strongest Desire for Wine, and were perpetually asking
for it, even those who at other Times used to be
