Impetigo, again, has four species. The least bad is that which presents a semblance to scabies; for there is redness and some hardness and ulceration and erosion. But it is distinguished from scabies because there is more ulceration and there are pustules like pimples, and in it is seen an appearance as of small bubbles from which after a time little scales are detached; and this recurs at fixed seasons. The second kind is worse, almost like a pimple, but rougher and redder; it has various shapes; small scales are detached from the skin surface; there is more erosion; it spreads more rapidly and widely, and both comes and goes at fixed seasons even more markedly than the previous sort; it is called rubrica. The third kind is worse still; for it is thicker, harder and there is more swelling; there are cracks in the skin and more active erosion. This form also is scaly, but the scales are black. It spreads widely and not slowly. It varies less in the times at which it increases or subsides, and is never quite got rid of: its name is black impetigo. The fourth kind, which is quite incurable, differs in colour, for it is whitish and like a recent scar, and has small pallid or whitish scales; some are like lentils, and when these are removed there is sometimes bleeding. Otherwise its humour is white, the skin hard and chapped; it spreads widely. Now all these kinds occur generally on the hands and feet; they also attack the nails. There is no more efficacious remedy than that which I have mentioned above as prescribed by Protarchus for scabies. But Serapion used soda 2·32 grams, and sulphur 4·64 grams, taken up with plenty of resin.
