If a Vein is open'd soon after the Distemper is come on, the Blood generally appears of a fresh florid Red; the _Crassamentum_ is rather of a lax gelatinous Texture, than dense or compact; the _Serum_ yellow, and in a large Proportion. The Urine is at first crude, and of a pale Whey-Colour: As the Disease advances, it turns yellower, as if Bile was diluted in it and soon after the Patient shews any Marks of Recovery, it commonly grows turbid, and deposits a farinaceous Sediment. They seldom have any Stools, if the Symptoms are favourable, from the Time when the Purging, which generally attends the Accession, ceases. This Discharge is frequently bilious, and without any Pain: Tho' these Circumstances differ in different Habits. They complain less of Thirst in this than in other acute Diseases. The Tongue is generally moist, and not often furr'd: In some nevertheless it is cover'd with a thick white Coat or Fur, and those who are so affected, often complain of Soreness about the Root of the Tongue. The _Uvula_ and _Tonsils_, tho' they are sometimes so much swell'd, as to leave but a very narrow Entrance into the Gullet, and this Entrance frequently surrounded with Ulcers or Sloughs; yet the Patients often swallow with much less Difficulty and Pain than might be expected under such Circumstances. They frequently complain, soon after they are taken ill, of an offensive putrid Smell, affecting their Throats and Nostrils, which oft occasions Sickness before any Ulcerations appear. In those who have this Disease in a severe manner, the Inside of the Nostrils, as high up as can be seen, frequently appears of a deep red, or almost livid Colour: After a Day or two, a thin corrosive _Sanies_, or with it a white putrid Matter of a thicker Consistence, flows from them, which is so acrid, as to excoriate the Part it lies upon any considerable time. This is most observable in Children, or in young and very tender Subjects, whose Lips likewise are frequently of the Colour above-mention'd, and cover'd on the Inside with Vesicles containing a thin _Ichor_, which excoriates the Angles of their Mouths, and the Cheeks where it touches them.
