, which he had recently founded. A number of German Jesuits responded to the call, among them Epping, who set out in June, 1872, for Quito to become professor of mathematics. He learned Spanish and wrote a textbook of geometry.
The political disturbances which followed the assassination of Moreno (6 August 1875) made it necessary for the Jesuits to return to Europe, and Epping arrived in the Netherlands in the fall of 1876. He spent the remaining years of his life at
Blijenbeck, and later at Exaeten, teaching astronomy and mathematics, devoting his leisure to research and literary work.

Eight years later he published ''Astronomisches aus Babylon oder das Wissen der Chaldäer über den gestirnten Himmel'' (Freiburg im Breisgau, 1889). This work was of importance both from the standpoint of astronomy and chronology. It contains an exposition of the astronomy of the ancient Babylonians, worked out from their
