_Lake of Geneva._--The chronicler Marius (in the second volume of _Dom
Bouquet_) mentions that, in the reign of the sons of Clotaire, an
earthquake or landslip, in the valley of the Upper Rhone, enlarged the
Lemannus, or Genevese Lake, by thirty miles of length and twenty of
breadth, destroying towns and villages. Montfaucon, in his _Monumens de
la Monarchie_, i. p. 63., {407} states that the Lake of Geneva was
formed on this occasion: absurdly, unless he means that upon this
occasion its limits were extended to Geneva, having previously
terminated further east. What vestiges of this catastrophe are now
perceptible?
