    the diaphragm (by changes in size of uterus, bladder, burst- ing of hepatic and diaphragmatic hydatid cysts, &c.) gives rise to erythema and urticaria. The mode of occurrence of the exanthem, its topography, its sudden disappearance prove sufficiently that this was not -a case of Hebra's E. multiforme exudativum but an evanescent reflex angio-neurosis. Polstebnoff mentions that in his two cases of E. papulatum in jaundice the dorsa of the hands were not affected. The author gives details of five other somewhat similar •cases, and claims to have shown that there are a number of angio-neurotic exanthemata, which are entirely different from, and easily distinguishable from Hebra's E. multiforme. Following Auspitz, he proposes to call these angio-neurotic exanthemata Erythanthemata (fpJ0poc = red ; ai<0oc = blos- som), and defines them as angio-neuroses of an erythemato- papular type. Urticaria is included in this group, but E. multiforme and nodosum (which Auspitz included in it) do not belong to it; no more does E. neuriticum, which is a con- gestive dermatitis, and, as Charcot and Mitchell have shown, somewhat akin to chilblain. The author in conclusion gives a classification of angio- neuroses : Type I. Anasmia. (1) Angio-spasm of the fingers ( dead fingers ). (2) Local asphyxia resulting in necrosis (Raynaud's disease). (3) Ergotism. Type II. Cyanoses. (1) Livedo annularis and frigore. (2) Perniosis. {3) Cyanotic form of local asphyxia. Type III. (Edema. {1) Acute circumscribed oedema (Quincke's disease). (2) Urticaria factitia.
