The fragment consists of six vellum leaves, or twelve pages, which apparently formed part of a gathering or quire of the original volume. The leaves measure 11-3/8 by 7 inches (286 x 180 millimeters); the written space measures 7-1/4 by 4-3/8 inches (175 x 114 millimeters); outer margin, 1-7/8 inches (50 millimeters); inner, 3/4 inch (18 millimeters); upper margin, 1-3/4 inches (45 millimeters); lower, 2-1/4 inches (60 millimeters). The vellum is well prepared and of medium thickness. The leaves are bound in a modern pliable vellum binding with three blank vellum fly-leaves in front and seven in back, all modern. On the inside of the front cover is the book-plate of John Pierpont Morgan, showing the Morgan arms with the device: _Onward and Upward_. Under the book-plate is the press-mark M.462.
