From the preceding Account of the Sore Throat attended with Ulcers, it will, I believe, appear, that this Disease is widely different from a common Sore Throat, or simple Inflammation of any of the Parts about the _Fauces_; both as to the Subject commonly affected by it, the Manner of its Attack, the Progress of the Symptoms, and its Conclusion: For the sore Throat with Ulcers generally attacks Children; and of these Girls more frequently than Boys, as hath been observ'd: If Adults are seized with it, they are commonly such as have been very much conversant with the Sick, or else are weak and infirm: And it seems to affect those Adults in the severest manner, who have been previously indisposed, or whose Strength has been reduced by unseasonable or immoderate Evacuations. On the contrary, the common _Angina_, or an Inflammation of the Tonsils, most frequently attacks the healthy, the vigorous, and robust; the weak, the delicate, and infirm, are less exposed to it, at least suffer less from it, than the former. As both Diseases are attended with a Fever, and as most Fevers come on with Shivering or Chilness, this Symptom may at least appear equivocal: But if Sickness, or Vomiting, or Purging, or an acute Head-ach, towards the back Parts or Top especially, or if all these, come on in the Space of a very few Hours, which they generally do, where the Disease is vehement, it may justly be esteem'd of the malignant or putrefactive kind: But if an erysipelatous Redness discovers itself in the _Fauces_, or if any Ulcerations or white Sloughs appear in them, the Disease is evident. In some Cases, the Symptoms have been so obscure, that it was difficult to determine to which Class they properly belonged: But in these Circumstances the Disorder was so favourable, that, supposing it not to be of the ulcerated kind, no other Inconvenience seemed likely to ensue from treating it as such, than a Suppuration; which is often an Event rather to be chosen than avoided. The Redness of the Skin in the Face, Neck, Breast, and Hands, is another obvious and distinguishing Characteristic, which in Children and young People especially, seldom fails to accompany this Disorder. In the common sore Throat, a local Inflammation is the Disease: All the Symptoms are derived from this Source: An acute throbbing Pain, greatly increased upon swallowing even Liquids, is the principal Grievance. In the other, the whole Habit suffers, as if by a _Stimulus_ of a peculiar Nature and although the Throat is always more or less affected, yet it is sometimes the least Part of the Patient's Complaint; and Instances have occurr'd to me of considerable Sloughs being formed, before any Soreness or Pain in the _Fauces_ hath been mention'd.
