attentively all the Symptoms and Variations of the 
Difeafe ; and then the periodical Return of the 
worfer Symptoms at dated Times will afford a 
very certain Proof that it is a Fever in Difguife. 
It ought alfo to be confidered whether the Fever, 
which is joined with another Difeafe, be only a 
Symptom of that Difeafe, or be an idiopathick 
Difeafe itfelf and complicated with the other : For 
if it be a Symptom of the other Difeafe, it will be 
in vain to attempt to remove it without curing the 
idiopathick Difeafe at the fame Time, by mixing 
the Bark with fuch Remedies as are indicated. But 
in a complicated Cafe, the Cure of both Difeafes 
may either be attempted together, or the Fever 
may be cured by the Bark though the other Difeafe 
Hill remains. 
It fometimes happens, when the Bark has not 
been given in due Quantities, that the febrile Mat- 
ter is fo far weakened that it no longer produces 
the ufual Paroxyfm or Exacerbation, but excites 
only fome Symptoms ; and thefe, though not fo 
violent, yet as they continue long, are no lefs trou- 
blefome to the Sick; fuch are Lofs of Strength- 
and Appetite, a Naufia , Anxiety in the Region of 
the Bread, Oppreffion of the Stomach, Inflation 
and Gripings of the Belly, a Cough, Pains of the 
Head, Night-Sweats, a Dropfy, cache&ick and 
rheumatick Affe&ions, or others of the like Nature. 
It is cudomary with the Vulgar to afcribe all thefe 
to the Bark ; though very unjuftly, fince the too 
fparing Ufe of it ought rather to be blamed, or 
elfe its Badnefs, it being either not genuine, or by 
fome Means impaired in its Virtues. For if the 
bed Bark be fele&ed and given in due Quantities, 
thefe Diforders will difappear in a little Time. 
In inflammatory, putrid, malignant, and pedi- 
lential Fevers, the Efficacy of the Bark feems in-
