His sojourn at Zurich lasted twenty-one years, when, in 1881, he returned to his own canton. He was not long, however, to breathe his native air, his laborious career being suddenly cut short in 1886. His works are numerous and varied, but all are remarkable for great power, authority, and calm. =Rauchenstein=, H., Der Feldzug Cæsars gegen die Helvetier, Zurich, 1882.--=Relatio Conflictus Laupensis.=--=Reportorium= der Abschiede der Eidgenössischen Tagsatzungen, 1803-1848, 3 vols.

Educated in Germany and Holland, he returned to Switzerland to become professor of history at the University of Lausanne. The _Histoire de la Réformation en Suisse_ was but a part of a projected general history of Switzerland which was never completed. Ruchat says of his labours: “I have been tempted nine times to give up the enterprise and live in peace; but the desire to serve my country has ever reinvested me with courage. I seek not glory, but truth and the public good. I have always endeavoured to write as though some day I were to be called to account for the products of my pen.” * * * * *
