only what was laft exhibited, mixed with 

 phlegm } and others again had what is called 

 the black vomit *. The reaching to vomit 

 continued a longer or fhorter time, according

* That which is called the Hack vomit, at firll fight, ap- 

 pears to be black ; but on a more careful examination, I 

 obferved, that this colour proceeded from a great quantity 

 offmall, flakey, black fubftances which floated in the liquor 

 thrown up by vomit ; but the colour of this liquor was 

 much the fame with that which the patient had laft drank, 

 -"ahd vVas by no means black. Tiiofe black flakey fubftances 

 are the bile mixed with, or adhering to the mucus which 

 Jined the ftomach. For, upon difl'edion of thofe who died 

 bf this difeafe, not only in this but former years, 1 always 

 obferved that the ?nucus of the ftomach was abraded, arid 

 the bile in its cyfiis was black and fometimes very vifcid. 

 In a Lad who died of this difeafe in the beginning of the 

 ■fourth day, and who was immediately opened, the bile was 

 not only black, bqt had the confiftence of thick Feuice-tar- 

 pentine, and was exceedingly tough. On the infide of the^ 

 ftomach, there were feveral carbuncles or gangrenous fpecks. 

 And in all thofe I have difTefted, who have died of this dif- 

 eafe, I have not only always obferved the fame, but like- 

 ways that the blcod was very fluid, and the veflels of the 

 'vifcera much diftended ; from whence I have been very in- 

 clinable to think, when the difeafe was not conquered in its 

 ia^Jladium, that, about the time of the termination of the 

 fever, there y^a zmitajlafii of the morbid matter to the 

 vi/cera.
