![ing on dilatation of the lymphatics, and arising from oft-recurring attacks of erj^sipelas, or chronic eczema. In these cases also the same treatment may be tried. I now pass on to consider a peculiar form of hypertrophy, followed by fatty degeneration of the cellular elements, and of the sheaths of the vessels, known as Xaoithelasma. The appearance of a dusky spot above the internal palpebral ligament, marks the commence- ment of this curious affection. It generally attacks women over forty, about fifty per cent, of whom have had, at one time or another, an attack of jaundice. The deformity occasioned by this yellow, dirty-looking frame around the eyes, is quite sufficient to justify excision of the altered portions. This may be easily done by raising the patches up with a forceps, and then snipping thein off with curved scissors. I am inclined to think that the early reiaoval of patches as soon as noticed, checks the further progress of the disease. In many cases where I have thus operated, I have requested the patients to return immediately, should an}^ new spots appear in the neighbourhood of those removed. I have not as yet had any cases of relapse. I now come to the subject of tumours of the lids, but will mention only two varieties, both of which frequently come under the notice of the ]Dractitioner, namely, granuloma and epithelioma. Cystic tumours, lipoma, sarcoma, and carcinoma, demand pm-ely surgical treatment, that is to say, removal, and need Hot therefore be considered here. Granuloma of the lids is also known as Chalazion. It was long confounded with atheromatous cysts, which are very rare in the skin of this part, and with a cystic dilatation of the meibomian glands, which singly never constitutes a chalazion. Still, this pathological change may help to form a granuloma by invading the interior of a tarsal gland, and bringing about the obliteration of its excretory duct, or by merely forming a diverticulum to the gland, and so causing it to assume a cystic development. A granuloma appears by preference on the external surface of the tarsus, on which it always, more or less, encroaches; it may, how- evei', primarily invade the felt-like tissue, as it increases dis- tending this in every direction, in such a manner as to thin the tarsus chiefly in the direction of the conjunctiva; lastly, it may become localised at the orifice of a tarsal gland, in which case it forms a prominent tumour most marked on the internal edge of the lid. In practice, chalazion may further be distinguished as external, c](https://iiif.wellcomecollection.org/image/b21948823_0037.jp2/full/800%2C/0/default.jpg)
