Though there was some difference in various subjects, yet he never once saw a 

 well-digested or concocted phlegm, or mucus: on the contrary, the greatest part 

 was of a jelly-like nature, glary, and somewhat transparent, mixed with a white 

 opaque thready matter, sometimes more, sometimes less, resembling a rotten 

 membranous body or slough. Such a slough he had seen generated on the skin 

 of one of these patients in the neck and arm, where blisters had been before ap- 

 plied. The blisters had been dressed with colewort leaves, and ran but little; 

 but, contiguous to them, small red pustules, not exceedingly fiery, arose, which, 

 sweating plentifully in a few hours, became quite white; these, hourly enlarging 

 their bases, united, and covered a large surface, fresh pustules arising in the 

 adjacent parts. This white surface had the aspect of an oversoaked membrane, 

 which, being oversoaked, was become absolutely rotten. The part blistered, if 

 not quite, was in effect dry, and the flux from the slough was incredibly great. 

 If he mistook not, clothes 10 times double, the child's shift, a double bed-gown, 

 were wet quite through, and a large spot was seen in the bed of some hands 

 breadth, and this in a very few hours. He scratched the slough with his nail ; it 

 separated with ease, and without being felt by the child. What , his nails took 

 off afforded the same appearance with the matter of the spittle before-mentioned. 

 Hence, he thought, he saw sufficient reason to convince him that the disorder in 

 the larynx and aspera arteria was similar to this, generated in the same manner, 

 and arising from the same internal cause; and supposing this conjecture true, the 

 production of every symptom seems easy to be accounted for. 



Dea 1748, while the morbus strangulatorius was at Liskard, a child here and 

 there had red pustules, not unlike the above, which broke out in the nape of 

 the neck, and threw off a surprising quantity of thin transparent ichor, vastly 

 glutinous when dry. These were easily cured in the beginning, if managed 

 aright; but, being drawn with colewort leaves, or poulticed according to the direc- 

 tion of our old female practitioners, the above mentioned slough was soon gene- 

 rated. Dr. S. was desired to look on a poor person's child in this unhappy situa- 

 tion, who, with little intermission for near 2 days, had bled profusely at the 

 nose; her pulse was almost gone; the bleeding was with difficulty stopped; but, 

 being quite exhausted, in about 6 hours she sunk in a faint fit. The slough 

 had spread from shoulder to shoulder, extended full a third down her back, 

 and seemed very thick. All treated in the above manner died. Scarifying af- 

 forded no relief. 



Now, though this was not properly the morbus strangulatorius, yet he appre- 

 hends it was analogous to it, and produced from the same cause; and it is likely, 

 had the anatomical knife been employed, what was seen on the back of one 

 might have been discovered in the aspera arteria of the other. There is a cir- 

 cumstance which adds to the probability of this opinion, viz. in one or more in-
