Condition report:
Both volumes show significant signs of age and shelf wear. The Burn volume (1854) exhibits wear to the extremities of the cloth boards and some foxing to the internal leaves, particularly the frontispiece and title page. The Rankine volume (1866) has more pronounced condition issues, including a split to the cloth at the head of the spine and a large area of discolouration or staining to the front board. There is significant foxing and toning throughout the text block of the Rankine volume. Neither volume contains a dust jacket.
