[72] Dr. _Pringle_ takes Notice of this yellow Colour or Jaundice. He says, “some grow yellow, as in the Jaundice. This was found more frequent during the first Campaign than afterwards; it was an unfavourable, but not a mortal Symptom.” _Observ._ part iii. ch. 4.--_Hippocrates_ mentions the Jaundice occurring in Fevers, _Aphor._ iv. § 62 & 64; and he reckons it a favourable Symptom in ardent Fevers, where it happens on the seventh Day. See _Book on Crises_’s, sect. 3. [73] Does this Fever, when accompanied with this universal Yellowness of the Skin, approach to the Nature of the yellow Fever of the _West Indies_? As I had so few Cases of this Kind under my Care, I cannot determine any thing about it from my own Experience; but, from the Accounts of others, I should believe them to be very different Disorders.--In the yellow Fever of the _West Indies_, the Blood appears quite loose and dissolved, without the least Appearance of Size, even on the first Day; and the general Yellowness appears on the third or fourth, with Signs of a total Dissolution, and gangrenous Diathesis of the Blood: Whereas, in the Remitting Fever of _Jamaica_, Mr. _Nasmith_ tells us, (See Dr. _Lind_’s first Paper on Fevers), there is always an inflammatory Diathesis of the Blood. The Yellowness in both depends on a Redundancy and Absorption of Bile; but in the yellow Fever of the _West Indies_, the Bile is in a much more putrescent 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.
