The difcharge of an unhealthy fore blackens filver probes, 

 and preparations of lead. This efl'ed is imputed by Dr. 

 Crawford to the fulphurated hydrogen gas generated in 

 the matter. Phil. Tranf. vol. Ixxx. for the year 1790.

Ufe of Paj. — By fome it is fuppofed to carry off humours 

 from the conilltution. Suppuration is fometimes regarded 



or iffues are made in found parts before allowing other 

 fores to be dried up. Suppuration is fometimes excited 

 with a view of making parts, fuch as indurated fwellings, 

 diflblve into pus ; but we have endeavoured to (hew that 

 no difi'olution of the folids is concerned in^ the produftion 

 of pus. 



A fecretion of pus is looked upon as a general prevention 

 oi many, or of all, the caufes of difeafe. Hence iilues are 

 made to keep off both univerfal as well as local difeafes. 

 However, the ufe of pus is perhaps unknown ; for it is 

 brmed mofl; perfedfly from healthy fores, and in healthy 

 :onllitutions ; and large difcharges from parts not very 

 ■flential to hfe, produce very little change in the conftitu- 

 lion, and as little upon being healed up, whatever fome may 

 luppofe to the contrary. 



This is certainly the cafe with many old ulcers, the fup- 

 ]uration from which feems to have httle or no effedl in 

 mpairing the health. Nor is there any real reafon to be 

 Ifraid of heaUng fuch ulcers, when poiuble, lell a worfe 

 lifeafe ftiould follow from the itoppage of the difcharge, 

 o which the fyllem is fuppofed to be habituated fo much, 

 hat the continuance of fuch difcharge is eflential to health. 

 Every one knows, that when there is no interference of 

 -rt, that is, when the furface of a fore is left uncovered, 

 ne thin part of the matter evaporates, and the thick part 

 ri-ies and forms a fcab. Nature, therefore, feems to have 

 •jficrned, that one ufe of pus (hould be to make a cover 

 irprnteftion for ulcerated furfaces. 

 Among the fecondary ufes of fuppuration may be men- 

 oned, opening a communication between a difeafe and the 

 -.ternal furface of the body ; forming a paflage for the 

 :it of extraneous bodies, &c.

PUSTULE, PusTULA, in Medletne, a fmall elevation 

 of the cuticle, upon an inflamed bafe, containing ^aj-. 



Pullules originate from an inflammation of the flcin, and 

 the confequent partial efliufion of purulent matter under the 

 cuticle, by which the latter is elevated into Imall circuin- 

 icribed tumours. Puftules are of various fizes, fometimes 

 very minute, and fometimes extending to half an inch in 

 diameter ; and they terminate either in fmall ulcerations, or 

 more commonly in fcabby crulls. Dr. Willan conftituted 

 an order of cutaneous difeafes under the head of pujiules, 

 including five genera, impetigo, porrigo, ecthyma, va- 

 riola, and fcabies ; but he never completed this part of his 

 work, a brief compendium of which has been drawn up by 

 Dr. Bateman. (See his Practical Synopfis of Cutaneous 

 Difeafes, 1813.) See alfo Impetigo, Poi;rigo, Small- 

 pox, and Itch. 



By many writers the ufe of the word pujlule is very 

 general, including not only purulent elevations of the fliin, 

 but veiicles and even pimples ; and it mull be admitted 

 that the befl; ancient authority fanftions even a more extenfive 

 acceptation of the word, including even wheals, " quae ex 

 urtica vel fudore nafcuntur." (Cellus, lib. v. cap. 28.) 

 But not only the etymology (quafi pus tullt), but accuracy 

 of language would lead us to limit the term to purulent erup- 

 tions, as in the above definition, and as fome correct writers 

 have done. See Prof. Arnemann, Comment, de Aphthis.
