Argument for Mr. Prescott in the matter of the appeal of Edison and Harrington from the decision of the Commissioner of Patents of March 20, 1875, to the Honorable the Secretary of the Interior. 14 pages. [The decision of Secretary Columbus Delano appears on pages 13-14.]
Although this pamphlet is not bound in Volume 72, Prescott's argument is part of the Patent Office proceedings involving the title to Edison's duplex and quadruplex patent applications and has therefore been selected with related documents in this volume.
