ever began to appear again among the Sick, sent
from the Army, to the Hospital at _Natzungen_; and it continued to be
frequent through the Summer and Autumn; and the greatest Part of these
Fevers this Year terminated in regular Agues, mostly in Tertians, and
were cured by the Bark; whereas the Year before very few terminated
this Way.

This Disorder in the Beginning had commonly the Appearance of a
continued Fever; and many had a Sickness and Vomiting, and threw up a
Quantity of yellow Bile, mixed with the Contents of the Stomach. In a
few Days, especially after Bleeding, the Remissions became clear; tho'
on its first Appearance in _June_ 1761 they were short, and rather
obscure; and it seemed still to partake a good deal of the Nature of
the common Inflammatory Fever, the Blood being very sizy; but as the
Season advanced, the Remissions became more evident, and the Paroxysms
more like those of an Ague; and the Blood less sizy, tho' at all
Seasons of the Year it had some Appearance of an inflammatory Buff in
this Disorder. The Sick were restless and uneasy at Night; but
commonly felt themselves cooler and lighter in the Day-Time: and
although they had no cold Fit, as the Fever came on at Nights, and
many of them no Breathing Sweat, as they became cooler and freer from
the Fever in the Morning; yet the Fits were so remarkable, that many
of the Patients used to say they had a regular Fit of an Ague every
Night, or towards the Morning; and some few, that they had the Fit
every second Night. As the Season advanced, the Remissions appeared
more distinct. However, there was always a good Number in whom the
Fever went on in a continued Form, through its whole Course, without
any Signs of Remission; tho' they had all the other Symptoms of this
Fever. In a few Instances the Fever, after it came to remit, changed
again into a continued Form.

The Heat in the Time of the Paroxysms rose high, and several were
delirious during its Continuance[70]; but were quite sensible in the
Intervals, though never wholly without the Fever.

[70] I did not see the Delirium rise so high, nor the
Paroxysms so severe, as in the Marsh Fever described by Dr.
_Pringle_.

At the End of _July_ 1761, four or five were attacked with a Bleeding
at the Nose, in the Time of the Paroxysms, and became cooler
afterwards; but it did not prove a Crisis in any of them.

The Urine in the Beginning was commonly of a high Colour, though
sometimes it
