Show Ichthyol. Tho Importation of Ichthyol, a peculiar pe-culiar nsphaltlc material found In Austria, Aus-tria, which finds application after appropriate ap-propriate chemical treatment ns a very Important medicament, has been, along with many other products, cut off by tho war. The raw material comes from a fosslllferous deposit near Secfeld, in tho Au3trlnn Tyrol. It Is carefully selected se-lected nnd subjected to dry distillation. Tho dlstlllato thus obtained Is then Eulphonntcd nnd subsequently neutralized neutral-ized with ammonia. Tho use of this material has greatly Increased In tho Inst fow years, and It has proved very beneficial. Almost Immediately following follow-ing tho beginning of tho war Its prlco doubled, going to over CO cents an ounco. Already, however, a firm In St. Louis has a material on tho market, which has been favorably recommended recommend-ed ns an efficient substltuto, closely resembling re-sembling Ichthyol itself.
