In cases not very severe or extensive, when the skin only is affected, the constitutional treatment already mentioned is first to be employed, and then the affected part must be freely punctured with a fine lancet, at numerous points, as recommended by Sir R. Dobson. These punctures should reach the vascular layer, but not go deeper: the serous effusion, if there be any, is thereby evacuated—the over-distended vessels are relieved of a considerable portion of their contents—and the œdematous swelling, with the formation of phlyctenæ, is prevented. The part is afterwards to be fomented for half an hour, or an hour, with bags containing chamomile flowers or hops; the fomentation, repeated at intervals, proves highly grateful to the feelings of the patient, allays any irritation which the making of the punctures may have produced, and keeps the skin perspirable. Under this treatment, every vestige of erysipelas will generally disappear in the course of a few days. In more severe cases, especially in the extremities, the parts must be freely incised. The incisions ought to extend through the integuments and cellular substance, and their length and number must be proportioned to the extent and severity of the affection. One or two pretty free incisions, if made in the proper place, where the greatest degree of boggishness, marking the disorganised state of the tissues, is discovered, will generally suffice—the vast good and the relief afforded depends partly upon the abatement of the tension, in consequence of the evacuation of the effused fluids—upon the unloading of the over-distended bloodvessels of the part, and upon the acceleration of the suppurative process, which is often critical. The constitution is, probably, relieved by the suppuration of the wounds, and the consequent drain of the offending particles.
