This is an inflammatory tumour or swelling, attended with redness, heat, pricking pain, tension or re-sistance, with pulsation or throbbing. Those phlegmons that are flight, without any previous indisposition, are most likely to disperse; those that follow a fever generally suppurate; those in very old or dropsical people, when in a soft part, often turn to a gangrene or mortification; when in a glandular part, to a schirrus or cancer: likewise the parts most distant from the heart are most likely to turn to a gangrene, and those nearest the heart to an abscess.

These inflammations may be dispersed by plentiful bleeding, by purging with Epsom salt, by living upon veal or chicken broth; by taking six or seven grains of nitre dissolved in broth, three or four times a day.

But you must never attempt to disperse these tumours, if there is danger of a gangrene, if they are critical, if they are behind the ears, under the arm-pits, or in the groin; if the humour is malignant, as in pestilential or venereal buboes, or from the bites of venemous beasts; if the pain is exceeding violent; if the patient has a bad habit of body; or lastly, if there is any eruption on the skin, as the herpes or the itch.

This tumour may be brought to suppuration by moist and emollient poultices, to relax and soften the skin. "Take of "the crumb of white bread eight ounces, of white soap an "ounce, of new milk a sufficient quantity, boil them toge-"ther a little." It may also be promoted by plasters, ointments, or other unctuous topics.

When the swelling is ripe, it may be opened with a knife or lancet, according to the direction of the fibres of the mus-cles, avoiding large branches of the blood-vessels, and in the most depending part. Venereal buboes and scrofulous tumours are best opened with causticks; in venereal and pestilential buboes, we must not wait till they are ripe.

When the abscess is opened, it may be drest at first with dry lint only, or with a soft digestive spread on dry lint. Over the dossils of lint, lay a large pledgit of tow spread with basilicon, which will lie much softer than a defensative plaster. The same dressings are to be continued with a proper regimen, till the cavity is filled up with flesh by nature, taking care that the bandage fit loose and easy: it may be cicatrised with dry lint or desiccative powders, keeping the margin clean and free from proud or fungous flesh, by making a moderate compres-sure with dry lint, or by levelling the surface with Roman vitriol or red precipitate: the dressings may be renewed in twenty four hours, in hot weather oftner, or when the discharge is great.
