State, and a great Part of the Cure depends on the early and
speedy Evacuation of it.--In the yellow Fevers which appeared
in _Haslar_ Hospital, which are taken Notice of by Dr.
_Lind_, in his _Two Papers on Fevers_, the Blood was in quite
a different State from what it is in the Yellow Fever of the
_West Indies_; the Blood drawn from two of these Patients
became covered with a thick yellow Gluten, and the Serum was
of the Consistence of a thin Syrup, and of a deep yellow
Tinge, and tasted bitter; and in another who was bled two
Days before his Death, it threw up the same thick yellow
Gluten, tho' the red Part below was quite loose.

I could not observe any certain critical Days, or Periods, when this
Disorder terminated.--Some, who had it slightly, got well in a few
Days; with others, it continued longer: Some continued long feverish,
and would seem cooler and freer from Fever for a Day or two, and then
grow worse again; and many had repeated Relapses.

Neither could I observe any regular Crisis in this Fever. Sweat was
the Discharge which oftenest proved critical. Many seemed to be
relieved by a Purging; but as the greater Part had a Looseness after
some Days, which continued often through the Disorder, without
producing any very sudden Change in the Symptoms, it seemed to be a
favourable Circumstance; though it seldom carried off the Fever so
suddenly as to be manifestly critical. The Urine broke, and dropt a
Sediment, for the most part, as the Fever took a favourable Turn.

When this Fever proved mortal, it commonly assumed a continued Form;
the Tongue became parched and dry, the Patient delirious, with
Twitchings of the Tendons, Hiccup, and other fatal Presages; while
others were seized with a violent Diarrhoea, or Dysentery, which sunk
them irrecoverably.

In the Beginning, it was absolutely necessary to bleed the Patients
freely; and frequently to repeat the Evacuation, where the Symptoms
required it. The Blood was of a florid Colour, and commonly threw up
more or less of an inflammatory Buff.

In these Fevers, we were obliged to have particular Regard to the
first Passages, especially in the Beginning of the Disorder; for they
were generally loaded with bilious Humours[74]; which, if suffered to
remain in the Bowels; were either absorbed, and increased the Heat
and Fever, or brought on a violent Diarrhoea; and therefore, after
Bleeding, we gave a Vomit in t
