    under observation, but I have not included these in my paper, as I have no new observations to offer thereon. In young infants at birth it is not at all unusual to see slight degrees of staining, due to some abnormal condition of the blood- vessels ; but this staining for the most part disappears spon- taneously during the early months of life. CoLOUK.—Among the foregoing, all shades from bright scarlet to plum colour, were observed. Sometimes the surface was dull, sometimes quite shiny; sometimes the nasvus was quite flat, sometimes considerably raised and papillated. I have seen some with overhanging margins, somewhat mushroom like. They are often covered with hairs, even when situated on parts not usually hairy; the hairs are then coarse and hypertrophied. The orifices of the skin glands, usually coarse and hypertrophied, can often be seen on the surface of these nsevi. Spontaneous Ulceration.—In nineteen of the cases, spon- taneous ulceration was going on when first seen, while in many others it was evident that a similar ulceration had taken place, from the presence of cicatrix on the surface of the naevus, not brought about by treatment. 'It would thus appear that spontaneous ulceration is by no means a rare condition; it is remarkable how seldom haemorrhage occurs under these circumstances. In one case only have I seen any considerable amount, and this occurred in a child with a well-marked hgemorrhagic diathesis. Spontaneous Cuee.—Though mentioned in text-books, I have not myself met with any cases of spontaneous cure. After destruction, by caustics, of the cutaneous portion, the subcutaneous part may cease to spread; doubtless the inflam- matory process finds its way into the deeper structures and helps to obliterate the vessels. I should not advise leaving a nsevus on any prominent position untreated in the hope that a spontaneous cure might set in; the more probable result would be a great increase in its size. Heredity, and Family Predisposition.—In a certain number of cases, a distinctly hereditary history was obtained. I have not, however, made inquiries on this score in the majority of my patients, and the details are therefore very incomplete. In many of the cases I found that other children in the same family were the subjects of nasvus. Nor have I found any causes predisposing to the development of nasvus. In only one case, have I recorded a haemorrhagic diathesis as present. Syphilis was not present in an undue proportion of the
