ous, or
whatever it may be, either mixed with the Blood, or lodged in
the Bowels, or in some other Part of the Body; that a great
Part of this Matter is thrown out of the Body, in the Time of
the Paroxysm; but that so much remains as serves by Way of a
Ferment to assimilate other Particles to its own Nature;
which, when collected in a certain Quantity, produce a new
Fit; and, according to the Time that it takes to produce this
Quantity, the Disorder assumes the Form of a Quotidian,
Tertian, or Quartan Ague.

The Soldiers were subject to this Disorder, particularly in Spring, if
they took the Field soon, and in Autumn: The Frequency of it was in a
great Measure determined by the Nature of the Ground on which they
were encamped, or the Situation of the Garrison or Town in which they
were quartered; for the lower and moister the Camp or Garrison, and
the more moist the Season, the more subject an Army is to Agues; and
the drier the Situation of the Camp or Garrison, and the finer and
drier the Weather is, the freer they are from Disorders of this Kind.

In Winter 1761, we had but very few Agues in the Hospitals; but on the
Return of the Troops from the Expedition into _Hesse-Cassel_, and
during the Spring, some (though not many) were attacked with Quotidian
and Tertian Agues, and but very few with Quartans.--In _July_ and
_August_ they were more frequent, and accompanied with more bilious
Symptoms. At _Bremen_, during the latter End of Autumn, and throughout
the Winter and Spring 1762, we had Agues of all Sorts, and many
inveterate Cases; and all this Spring, and during the Summer and
Autumn, the Ague was the epidemic Disorder all over _Westphalia_, as
well as among the Troops.

In Spring 1761, what Agues we had were mostly Tertian, some Quotidian,
and but two or three of the Quartan Kind. They were, for the most
part, mild, and yielded to the Bark.--Some of them began in the Form
of a continued Fever; but after Bleeding, and the Use of the cooling
Medicines for a few Days, they began to remit, and at last ended in
regular Quotidian or Tertian Agues: Others, at first, appeared in Form
of Remittent Fevers, attended with a strong throbbing Pulse; but
changed to regular Intermittents by pursuing the antiphlogistic Method
of Cure; and some from the Beginning assumed the Type of Quotidian or
Tertian Agues, but often attended with a good deal of Fever, for the
first two or three Days; and
