This book, "Function Und Begriff Vortrag gehalten in Der Sitzung Vom 9. Januar, 1891 Der Jenaischen Gesellschaft F?r Medicin Und Naturwissenschaft", by Gottlob Frege, is a replication of a book originally published before 1891. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible.
