On the Identity of Erysipelas and Acute Lymphangitis.  Verneuil and Clado, after many microscopical experiments, say on this subject: Erysipelas and acute lymphangitis are two affections, closely related to each other, which are best and most frequently observed on the surface of the body, the nature and relations of which have often been discussed without all perfectly agreeing on these points. Some consider them one and the same disease, or at the most two forms of the same disease; others separate them entirely, although admitting that they may exist at the same time and become one.Those taking the former view (among whom are Verneuil and Clado) advance the following arguments:1. They have the same anatomical seat in common; lymphangitis occupies the trunk, and erysipelas the branches of the lymphatic system; both invade the ganglions.2. The similarity in the pathological process; the two affections present, wherever they are visible, the
