A small phlegmon, which appears under the form of a conical, hard, circumscribed tumour, having its seat in the dermoid texture. At the end of an uncertain period, it becomes pointed, white or yellow, and gives exit to pus mixed with blood. When it breaks, a small, grayish, fibrous mass sometimes appears, which consists of dead areolae tissue. This is called the Core, Setfast, Ventriculus seu Nucleus Furunculi, (F.) Bourbillon. The abscess does not heal until after its separation. The indications of treatment are,-to discuss by the application of leeches and warm fomentations, - or, if thus cannot be done, to encourage suppuration by warm, emollient cataplasms. When suppuration is. entirely established, the part may be opened or suffered to break, according to circumstances. The term blind boil is given to an indolent, imperfectly suppurating, phlegmonous tumour, of the kind described above, which is often seated in a sebaceous follicle, as in Acne indurata.
