Bouvier's Law Dictionary, Revised 6th Ed (1856):

SCHEDULE, practice. When an indictment is returned, from au inferior court
in obedience to a writ of certiorari, the, statement of the previous
proceedings sent with it, is termed the schedule. 1 Saund. 309, a, n. 2.
     2. Schedules are also frequently annexed to answers in a court of
equity, and to depositions and other documents, in order to show more in
detail the matter they contain, than could otherwise be conveniently shown.
     3. The term is frequently used instead of inventory.
