the use of those cataplasms : not to say, that these are rather an argument of 

 the benefit arising from their use. 



In the confluent kind, generally a micturition and dysury came on about the 

 12th or 13th day; and that when no blisters were applied. If a large quantity 

 of turbid urine followed, it was soon succeeded by urine, which deposed a very 

 large sediment ; but if it proved thin and limpid, and in small quantity, a deli- 

 rium, tremor, subsultus tendinum, and other convulsive symptoms soon 

 followed. 



There were no symptoms so certainly fatal, at the turn of these small-pox, 

 as a delirium ; and, what is of constant ill omen in all kinds of eruptive fevers 

 at the state of the disease, a dyspnoea, or the anhelosa respiratio : bleeding on 

 the first appearance of them, frequently saved the patient ; the omission of 

 which a few hours, made the case irrecoverable. 



It was very common in persons afflicted with these pox, that 8 or 10 pustules 

 would run together, and form a large vesication, full of a limpid, crude matter, 

 which would continue so several days after the incrustation. In one that died, 

 mortifications were seen under these bladders. It was necessary to let out this 

 matter with a lancet, or needle, as soon as possible, lest it should cause an ul- 

 ceration, as it did when left to itself. 



In two patients, several of the pustules were filled with a bloody sanies : it 

 was surprising to find one of them get so easily over the distemper, though she 

 laboured also under the flux kind. 



The desquamation was very slow ; the black crusts adhering several days, 

 nay weeks, after the turn, while abundance of purulent matter gleeted from 

 under them. These left very ugly cicatrices. No application seemed to have a 

 better effect, in this case, than frequently fomenting the parts with warm milk, 

 or milk and water ; this diluted the acrid salts, washed them oft', and softened 

 the skin : oily liniments, by stopping the pores, are frequently hurtful. 



In a case or two a repullulation of pustules under the crusts in the face and 

 hands, when thrown off", were observed. This particularly in the boy, that 

 recovered with purple spots. The latter were distinct, though the former were 

 in the greatest degree confluent. 



Nothing so certainly abated, an<l took off" the secondary fever after bleeding, 

 if indicated, as gentle cathartics; such as rhubarb, manna, tartar, infus. senn. 

 and the like. The hot, scammoniate, aloetic purgers, seem not so proper, at 

 least, to begin with. These were given the 10th, llth, I'ith, or 13th days, 

 if the patient had a quick pulse, feverish heat, dry tongue, head-ach, restless 

 anxiety, and other symptoms of the putrid fever. Some one, or other of
