    and may, as when they occur on other parts of the body, be divided into the erectile and the non-erectile, the passive and the active, or the cutaneous and sub-cutaneous. They may occur on any part of the external surface of the eye- lids, varying in extent, colour, and elevation, from that of a small shot, of a purple hue, occupying the border of the tarsus, to a tumour the size of a vpalnut, but in shape and colour resembling a ripe mulberry, and engaging the entire Hd, or even proceeding from and often filling up a portion of the orbit. So many, and often such contradictory names, have been applied to naevus maternus of the eyelids, both con- genital and acquired, that the superficial or inattentive reader is liable to fall into error, not only in nomenclature, but in a practical and diagnostic point of view; and in a disease of this nature, often endangering life, yet frequently proving innoxious, it is of the utmost consequence rightly to under- stand its peculiar nature, its seat, and its varieties. Angiek- tasia, Telangiektasia, Tumor fungosus sanguineus, Morum congenitum patpebrarum, Gefdss-Erweiterung, and Balg- geschwulste, are applied to this disease by the Germans— the Tumeur erectile of the French, but Mauuoir distinctly calls it Fungus hcsmatodes ; while among English and Ame- rican surgeons it is known as the Aneurism by anastomosis of John Bell, its original describer, ncevus maternus, aneurisma racemosum, and varicose aneurism, ^c. Mr. Middlemore, as would appear from his work, considers nasvus and varicose aneurism as distinct from aneurism by anastomosis. Much of this confusion of names appears to arise from the pecu- liarity of the seat, the active or passive character, the colour, and the predominating vascularity of the tumour, as whether it is venous or arterial. This congenital disease often appears as a small, irregu- lar, slightly-raised, pale red mark on the lids, but increasing somewhat in size, and particularly in depth of colour (fre- quently assuming a bright scarlet), on the infant crying or making any exertion ;—or, it may be raised, and of the shape
