the right lobe, on which there were many large livid fpots, 

 thongli neither rotten or ofFenfive; and the left lobe had 

 fmall black fpots on it> refembling thofe marks left under 

 thefkinby gun powder. Upon cutting into any of the 

 larger fpots, which appeared on the right lobe, a bloody 

 fauies iffued from them without frothing, whereas upon 

 cutting thofe parts which appeared found, a whitifh froth, 

 but flightly tinged with blood, followed the knife. 



This is a faithful hiftory of this complaint, as it ap- 

 peared in all the cafes I have met with. 



Dr. Douglas^ of Bofton, in the year 1736, publilhed 

 an account of the firft appearance ofthedifeafe in this 

 country; from which I find that it put on much more ma- 

 lignant and putrid fymptoms at that time, than it has late- 

 ly been attended with, efpecially in this city, where dif- 

 eafcs of the putrid kind feldom occur; and was fo con- 

 ftantly attended with the eryfipelatous fymptoms, that he 

 terms it an eruptive miliary fever, with an angina uleuf- 

 culofa. And even in this place, fome of the oldeft, and 

 moft refpedable praditioners, aifure me, they have feen, 

 but a few years ago, the fame difeafe of which I am now 

 treating, attended both with the eryfipelatous appearances- 

 and highly putrid fymptoms. 



Upon the whole, I am led to conclude that the prefent 

 difeafe, as well as other fimilar difeafes, which have made 



their appearance at different times, and in different places, 

 arofe from a particular difpofition of the air, or miafmata 

 Jul generis } which more or lefs, according to particula^r 

 circumftances, generate an acrimony in the humours, and 

 difpofe them to putrefadion; and which have a fingular 

 tendency to attack the throat and trachea, affeding the 

 mucous glands of thefe pans, in fuch a way, as to occafi- 

 on them to fccret their natural mucus, in greater quanti- 

 ties than is fufficient for the purpofcs of nature: And 

 which in this particular fpecies, when fecreted, is either 

 really of a tougher or more vifcidconfiflcnce than natural,, 

 or is difpofed to become fo from refl: and ftagnatiom
