A number of printing errors have been corrected without comment (e.g. missing quotation mark, missing letter). There are some inconsistencies in how the author spelled German cities/regions in the original publication. Notations in English, German with umlauts and German without umlauts are found. The following changes have been made:
Wurzburg changed to Würzburg, Siebenburgen to Siebenbürgen, Nuremburg to Nuremberg, Furstenberg and Furstenburg to Fürstenberg.
On pg. [3] portable was changed to potable.
Archaic spelling retained.
