The idea here is that Victor would travel northeast to Basel on the confines of Switzerland,
thence follow the Rhine to Strasbourg, where he would be met by Clerval who, suspending
his course of studies at the University of Ingolstadt, would have travelled west across
Germany to join him. The two would then proceed north by boat through Germany into
Holland where the Rhine empties into the North Sea just beyond Rotterdam. This is
essentially the return route followed by Mary Godwin and Percy Shelley in their 1814
excursion memorialized in A History of a Six Weeks' Tour.
