Not illustrated. 1873 edition.

The epidermis is very loosely attached. If the crusts are removed, they are again quickly produced, and when cleansing the lids is neglected they reach a considerable size in a short time. e. The cartilage is scarcely ever primarily and independently inflamed. But inflammation of the tarsal glands (blepharitit tarsalis) is frequently observed. Yet all the tarsal glands are never inflamed, or even the whole of one single gland. At least, the certain proof of such a process is as yet wanting. The inflammation is confined to single acini, or to a portion of the common tube. The pathological process is the same in its nature as in acne ciliaris. The anatomical peculiarities, however, the great distance of the acini from the mouths of the glands, the washing over of the inner lip of the lid with lachrymal fluid, the displaced position and the involution of the greater part of the gland in a firm, undistensible, fibrous tissue, cause many peculiarities. It is to be ascribed to this, that low grades of the process are not noticed. There must be quite a severe proliferation of tissue, in order to soften the cartilage which participates in it, and to cause it to be distended by the glandular contents, and also to involve the more superficial layers in the process, and thus making the redness and swelling of the inflammatory collection noticeable externally. The product of the proliferation of tissue is purulent, as is necessitated by the severity of the process; either pure pus, or a thickish gelatinous mass streaked with blood, which more exact examinations have shown to...
