I well recolleft to have obferved rpund pellucid globules, like 

 \vhat are often feen on vines in hot-houtes, no larger than the 

 fmalleft pins' heads, adhere to her neck and bofom ; which were 

 to the touch, but were eafily rubbed off. Thefe difeafes, 

 if they are allied, do not differ more than the kinds of fmall-pox ; 

 but require many further obfervations. 



The eruption Vo often feen on children in the cradle, and call- 

 ed by the nurfes red-gum, and which is attended with fome de- 

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

 the contact of flannel next their tender (kins, like the miliaria 

 fudatoria ; and like that requires cool air, cool clothes, and lin-

13. Peftis. The plague, like other difeafes of this clafs, feems 

 to be fometimes mild, and fometimes malignant ; according to 

 the teftimony of different writers. It is faid to be attended 

 with inflammation, with the greateil arterial debility, and to be 

 very contagious, attended at an uncertain time of the fever with 

 buboes and carbuncles. Some authors affirm, that the conta- 

 gion of the plague may be repeatedly received, fo as to produce 

 the difeafe ; but as this is contrary to the general analogy of all 

 contagious clifeafes, which are attended with fever, and which 

 cure themfelves fpontaneoufly , there is reafon to fufpecl:, that 

 where it has been fuppofed to have been repeatedly received, 

 fome other fever with arterial debility has been miftaken for it, 

 as has probably univerfally been the cafe, when the fmall-pox 

 has been faid to have been twice experienced. 



M. M. Venefeftion has been recommended by fome writers 

 on the firft day, where the inflammation was fuppofed to be at- 

 tended with fufficient arterial flrength, which might perhaps 

 fometimes happen, as the bubo feems to be a fuppuration ; but 

 the carbuncle, or anthrax, is a gangrene of the part, and (hews 

 the greateft debility of circulation. Whence all the means be- 

 fore enumerated in this genus of difeafes to fupport the powers 

 of life are to be adminiftered. Currents of cold air, cold water, 

 ice, externally on the hot parts of the fkin. 



The methods of preventing the fpreading of this difeafe have 

 been much canvaffed, and feem to confift in preventing all con- 

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

 remove the fick into tents, on fome airy common, by the fide of 

 a river, and fupply them with freih food, both animal and veg- 

 etable ; with beer and wine, in proper quantities ; and to encour- 

 age thofe who can, daily to waih both their clothes and them- 

 felves. 



The pejl'is vnccina, or difeafe amongfl the cows, which afflict- 

 ed this ilhnd about half a century ago, feems to have been a
