11. Febris a pure contagiofo. Fever from contagious pus. 

 When the contagious matters have been produced on the exter- 

 nal habit, and in procefs of time become abforbed, a fever is 

 produced in confequence of this reabforption \ which differs 

 with the previous irritability or inirritability, as well as with the 

 fenfibility of the patient. 



1 2. Febris variolofa fecundaria. Secondary fever of fmall-pox. 

 In the diftinc"l fmall-pox the fever is of the fenfitive irritated or 

 inflammatory kind ; in the confluent fmall-pox it is of the fenfi- 

 tive inirritated kind, or typhus gravior. In both of them the 

 fwelling of the face, when the matter there begins to be abforb- 

 ed, and of the hands, when the matter there begins to be ab- 

 forbed, fhew, that it flimulates the capillary veflels or glands, 

 occafioning an increafed fecretion greater than the abforbents 

 can take up, like the action of the cantharides in a blifter ; now 

 as the application of a blifter on the flcin frequently occafions 

 the ftrangury, which fliews, that fome part of the cantharides is 

 abforbed ; there is reafon to conclude, that a part of the matter 

 of fmall-pox is abforbed, and thus produces the fecondary fever. 

 See Clafs II. 1. 3. 9. And not fimply by its ftimulus on the 

 furface of the ulcers beneath the fcabs. The exfudation of a 

 yellow fluid from beneath the confluent eruptions on the face 

 before the height is fpoken of in Clafs II. 1. 3. 2. 



The material thus abforbed in the fecondary fever of fmall- 

 pox differs from that of open ulcers, as it is only aerated through 

 the elevated cuticle ; and fecondly, becaufe there is not a con- 

 ftant fupply of frefh matter, when that already in the puflules 

 is exhaulted, either by abforption, or by evaporation, or by its 

 induration into a fcab. Might not the covering the face af- 

 fiduoufly and exaclly with plafters, as with cerate of calamy, or 

 with minium plafter, by precluding the air from*the puflules, 

 prevent their contracting a contagious, or acefcent, or fever-pro- 

 ducing power ? and the fecondary fever be thus prevented entirely. 

 If the matter in thofe puflules on the face in the confluent fmall- 

 pox -were thus prevented from oxygenation, it is highly proba- 

 ble, both from this theory, and from the fa<fts before mentioned, 

 that the matter would not erode the fkin beneath them, and by 

 thefe means no marks or fears would fucceed. 



13. Febris car cinomatof a. Fever from the matter of cancer. 

 In a late publication the pain is faid to be relieved, and the fe- 

 ver cured, and the cancer eradicated, by the application of car- 

 bonic acid gas, or fixed air. See Clafs II. 1.4. 16.
