This is the record of careful investigations of the action of formalin on the achorion, both culturally and on the diseased scalp. The results show the absolute futility of using formalin in a watery solution, but the authors think that further work on the action of spirituous solutions and vapour is desirable. A. W. ON A CASE OF ERYTHEMA NODOSUM OF UNUSUAL COURSE AND ATYPICAL LOCALISATION. EINIS. (_Derm. Zeitschr._, Bd. xi, Heft 7. p. 493.) A little boy, aged 2-1/2 years, was brought up with four slightly raised swellings, two, each as large as a half-crown, being situated symmetrically on the cheeks, and two, each as large as a sixpence, on the temples. The history showed that exactly a year before the child had suffered from a similar eruption on the lower legs, and the doctor who treated the child for former attacks identified the eruption with the fresh one. The peculiarity in the course showed itself in the access of colour and pain in the nodes every day about noon, though there was no fever, and the child seemed to be in very good health with the exception of a few swollen sub-maxillary glands. A. W. SEVERAL CASES OF ATROPHY OF THE SKIN. ALEXANDER. (_Derm. Zeitschr._, Bd. xi, Heft 5, p. 338.) Four cases in all are alluded to in this paper. The first patient, a man aged 31 years, showed all the symptoms of an epidermolysis bullosa, with slight ulceration, but the affection was said to have begun at the age of 18 and only to occur periodically. The second case was that of an old woman, aged 70 years, who also had an abdominal tumour, of which she died. Material showed that there was a complete loss of the papillæ, the elastic tissue had disappeared to only the slightest traces, and there were signs of inflammatory infiltration present. The third case was that of a woman, aged 55 years, with marked syringo-myelia; and the rash, which appeared as small nodules, terminating in atrophy, affected the axillæ, the inner sides of the upper arms, the groins, the inner sides of both thighs, the back, and abdomen. The author says that one is tempted to connect this with the condition of the cord, but to do so is the purest theoretical speculation. The fourth case was a woman, aged 42 years, who showed on the left side of the nose a circular patch as large as a sixpence, over which the skin was of a bluish-red colour, and somewhat infiltrated. There were some scars caused by the therapeutic use of electrolysis. (From the short description of this last case it does not seem clear why the diagnosis of Lupus erythematosus was not made.—A. W.)
