tered it fully. Therefore his work is one of the few epochal publications of our time.
In the following demonstrations, the reader will, on the whole, easily distinguish what originated with Morgan and what was added by myself. In the historical sections on Greece and Rome, I have not limited myself to Morgan's material, but have added as much as I could supply. The sections on Celts and Germans essentially belong to me. Morgan had only sources of minor quality at his disposal, and for German conditions—aside from Tacitus—only the worthless, unbridled falsifications of Freeman. The economic deductions, sufficient for Morgan's purpose, but wholly inadequate for mine, were treated anew by myself. And lastly I am, of course, responsible for all final conclusions, unless Morgan is expressly quoted.
