This volume, along with three others numbered 70, 71, and 73, forms a set with the general title "Cases and Points" and the specific title "Quadruplex Case" on their spines. Volume 72 contains Patent Office proceedings for 1875 and 1876 and closely related litigation involving rights and title to seven Edison patent applications pertaining to duplex and quadruplex telegraphy. This volume appears first in the sequence because most of its documents relate to Patent Office proceedings that chronologically precede the civil court records contained in the other three volumes. The volume has been selected in its entirety with a few exceptions indicated below.

1. Reply of counsel for Mr. George B. Prescott to the respective briefs of B.F. Butler, Esq., counsel for Edison, and John H. B.
