CLASS II. 1. 3. lo. OF SENSATION. 



I well recollect to have observed round pellucid globules, like 

 what are often seen on vines in hot-houses, no larger than the 

 smallest pins' heads, adhere to her neck and bosom; which were 

 hard to the touch, but were easily rubbed off. These diseases, if 

 they are allied, do not differ more than the kinds of small-pox; but 

 require many further observations. 



The eruption so often seen on children in the cradle, and call- 

 ed by the nurses red-gum, and which is attended with some de- 

 gree of fever, I suspect to be produced by too great warmth, and 

 the contact of flannel next their tender skins, like the miliaria 

 sudatoria; and like that requires cool air, cool clothes, and linen 

 next their skin. 



13. Pestis. The plague, like other diseases of this class, seems 

 to be sometimes mild, and sometimes malignant; according to 

 the testimony of different writers. It is said to be attended with 

 inflammation, with the greatest arterial debility, and to be very 

 contagious, attended at an uncertain time of the fever with bu- 

 boes and carbuncles. Some authors affirm, that the contagion 

 of the plague may be repeatedly received, so as to produce the 

 disease; but as this is contrary to the general analogy of all con- 

 tagious diseases, which are attended with fever, and which cure 

 themselves spontaneously; there is reason to suspect, that, where 

 it has been supposed to have been repeatedly received, some 

 other fever with arterial debility has been mistaken for it, as has 

 probably universally been the case, when the small-pox has been 

 said to have been twice experienced. 



M. M. Venesection has been recommended by some writers 

 on the first day, where the inflammation was supposed to be at- 

 tended with sufficient arterial strength, which might perhaps some- 

 times happen, as the bubo seems to be a suppuration; but the 

 carbuncle, or anthrax, is a gangrene of the part, and shews the 

 greatest debility of circulation. Whence all the means before 

 enumerated in this genus of diseases to support the powers of life 

 are to be administered. Currents of cold air, cold water, ice, 

 externally on the hot parts of the skin. 



The methods of preventing the spreading of this disease have 

 been much canvassed, and seem to consist in preventing all con- 

 gregations of the people, as in churches, or play-houses; and to 

 remove the sick into tents, on some airy common, by the side of 

 a river, and supply them with fresh food, both animal and vege- 

 table; with beer and wine, in proper quantities; and to encou- 

 rage those who can, daily to wash both their clothes and them- 

 selves. 



Thepestis vaccina, or disease amongst the cows, which afflict- 

 ed this island about half a century ago, seems to have been a
