Ichtheyol a Kind of Asphalt.

In a report on asphalt by the United States geological survey the following Interesting remarks about ichthyol are found: “A peculiar form of ashphaltic material found in Austria finds application, after appropriate chemical treatment, as a medicament under the name Ichthyol (and used for erysipelas, eczema, etc.). It Is not prepared in the United States. The raw material from which it is derived is a fossiliferous deposit which is found near Seefeld, in the Austrian Tyrol. The material mined at this place is carefully selected as to grade and is subjected to dry distillation. The distillate thus obtained is then sulphonated and subsequently neutralized with ammonia. The finished product resulting from this process is the commercial article known as ichthyol. The exact chemical composition of ichthyol has not been determined.”
