has a very putrid smell, produce hectic fever or typhous? Sec 

 Class II. 1. 4. 16. 



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

 When the contagious matters have been produced on the external 

 habit, and in process of time become absorbed, a fever is produced 

 in consequence of this reabsorption; which differs with the pre- 

 Vious irritability or inirritability, as well as with the sensibility 

 of the patient. 



12. Febris variolosa secundaria. Secondary fever of small-pox. 

 In the distinct smail-pox the fever is of the sensitive irritated or 

 inflammatory kind; in the confluent small-pox it is of the sensi- 

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

 swelling of the face, when the matter there begins to be absorbed, 

 and of the hands, when the matter there begins to be absorbed, 

 shew, that it stimulates the capillary vessels or glands, occasion- 

 ing an increased secretion greater than the absorbents can take 

 up, like the action of the cantharides in a blister; now as the ap- 

 plication of a blister on the skin frequently occasions the stran- 

 gury, which shews, that some part of the cantharides is absorbed; 

 there is reason to conclude, that a part of the matter of small-pox 

 is absorbed, and thus produces the secondary fever. See Class II. 

 1. 3. 9. And not simply by its stimulus on the surface of the 

 ulcers beneath the scabs. The exsudation of a yellow fluid from 

 beneath the confluent eruptions on the face before the height is 

 spoken of in Class II. 1. 3, 2. 



The material thus absorbed in the secondary fever of small- 

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

 the elevated cuticle; and secondly, because there is not a constant 

 supply of fresh matter, when that already in the pustules is ex- 

 hausted, either by absorption, or by evaporation, or by its indura- 

 tion into a scab. Might not the covering the face assiduously and 

 exactly with plasters, as with cerate of calamy, or with minium 

 plaster, by precluding the air from the pustules, prevent their con- 

 tracting a contagious, or acescent, or fever producing power? and 

 the secondary fever be thus prevented entirely. If the matter in 

 those pustules on the face in the confluent small-pox were thus 

 prevented from oxygenation, it is highly probable, both from this 

 theory, and from the facts before mentioned, that the matter 

 would not erode the skin beneath them, and by these means no 

 marks or scars would succeed. 



13. Febris carcinomalosa. Fever from the matter of cancer. In 

 a late publication the pain is said to be relieved, and the fever 

 cured, and the cancer eradicated, by the application of carbonic 

 acid gas, or fixed air. See Class II. 1 , 4. 16.
