30 PHILOSOPHICAL TRANSACTIONS. [aNNO 1713. 



is frequently attended with a shivering, bilious vomiting, &c. According to 

 the greater or less power of the latent miasma, the symptoms are always more 

 or less violent. 



The petechiae or malignant spots, which are always very dangerous, especially 

 in this contagion, raged violently. I have observed of them also 4 distinct 

 species. The first look like flea-bites, and have been called by some authors 

 pulicares. They break forth reddish, and soon changing their colour, grow 

 brown, and at last black. They are round, and spread all over the body, ex- 

 cepting the face, where they are not always found. The 2d species appears in 

 the form of lentils, and are called lenticulares; they are likewise at first ruddy, 

 but in about 24 hours change colour, becoming dark and ash-coloured: *they 

 Spread, as the former, all over the body. The 3d sort appears in large round 

 spots, of the same colour as the former, but are found only here and there on 

 the body: sometimes they are also intermixed with the lentil kind. The 4th 

 species is not unlike the measles, and spreads all over the body. After 2 or 3 

 days you find them shoot into little blisters rising to a head, but containing no 

 matter. They dry away the 5th day, at which time the patient's death is not 

 far off. After they are dried away, the skin is rough, and much like that of a 

 smoked goose, only not quite of the same colour. To these might be added a 

 5th species. These appear not till after death, either in points, or spots. They 

 show themselves mostly on the back and breast, and give plain indication that 

 there was a malignity which killed the patient. 



Many pernicious symptoms appear also at the breaking out of these several 

 petechise; as pain in the head and loins, vomiting, diarrhoea's, palpitations of 

 the heart, great anxieties, faintings, shivering in all parts of the body, which 

 are frequently succeeded by heat or sweat, deliria, epileptic fits, lethargy, a 

 dismal hippocratic face, staring eyes, bleeding at the nose, inordinate menstrual 

 fluxes. In short the symptoms are so many and various, that it is impossible 

 to observe them all. 



Next are the pi ague- stripes or rays, called, by Joh. Bapt. Sitonius, vibices, 

 and by others, molopes. They are not seen before the latter end, for death 

 itself attends them : and this used to happen very unexpectedly, though the 

 symptoms were tolerable, and attended by hopes of recovery; yet like lightning 

 they shot upwards from the breast to the face, all in strokes of various colours, 

 blue, green, brown, and yellow; first covering the face as high as the nose, 

 and from thence spreading farther to the forehead. This so disfigured the 

 patient, that he was frightful to behold: his eyes grew stiff, his tongue trembled, 

 his speech gradually ceased, and inwardly there was great anxiety and confusion; 

 from all which the struggle between life and death might well be observed.
