21. Maps of Oxford and Cambridge, by Ralph Aggas; the former dated 1578,
the latter 1592; about three feet by four in size.
These extremely curious and valuable maps were bequeathed by Dr.
Rawlinson. Having become decayed and dilapidated by exposure, they
were some few years ago carefully mounted on canvas, on a wooden
frame, and covered with glass; by which means they are effectually
secured from further injury of the same kind.
