rmany_, tells us, that the
Malignant Fever broke out in a violent Degree, and Half the Number
died by the Way, and federal others soon after their Arrival[147].

[146] During the Campaign in _Hungary_, in the Year 1717,
Count _Boneval_ preserved both himself and Family from
Disorders, by taking himself, and making all his Domesticks
take, two or three Times a Day, a small Quantity of Brandy,
in which Bark had been infused, at a Time when all the Rest
of the Army were infected with malignant Disorders. A
Regiment in _Italy_ continued healthy by the Use of the Bark,
when the Rest of the _Austrian_ Army, who did not pursue the
same Method, were greatly annoyed with Sickness. See
_Kramer._ quoted by Dr. _Lind_.

Commanding Officers ought always to endeavour to proportion the Time
the Men are to be upon Duty to the Weather and the Nature of the
Climate. The Time of standing Centinel in very hard Frost, and in cold
wet Weather, or in the Heat of the Day in Summer, when the Weather is
very warm, and in hot Climates, ought to be shorter than when the
Weather is dry and more temperate.

The Marches of Troops ought, if possible, during the Time of very hot
Weather, to be made either very early in the Morning, in the Evening,
or at Night; and Officers, during the Course of an active Campaign,
ought to spare their Men as much as possible.

And when they are in Quarters, and have nothing to do, they should
narrowly inspect into their Manner of living; and have them out daily,
when the Weather will permit, and exercise them, or march them two or
three _English_ Miles a-Day, in order to prevent their falling sick
for want of Exercise; for Soldiers left to themselves are very subject
to Diseases when they come into Quarters after an active Campaign, by
leading too indolent a Life, if Officers do not take Care to prevent
it. However, at such Times, the Exercise ought to be moderate, and the
Men should not be brought out in wet Weather.

OF MILITARY HOSPITALS.

Whenever Men are seized with Distempers, they ought immediately to be
separated from those in Health, and either sent to the Regimental[148]
or General Hospital.

[148] Some of the regimental Surgeons in _Germany_, when they
took the Field, had always some spare Tents carried along
with their Medicine Chests; and when any of their Men fell
sick in Camp, and they co
