The red boards are stained, the preliminaries foxed and the edges of the pages are damaged from page 50 to page 90. This does not affect the print. A sound, though externally unattractive copy, which looks unprepossessing, but is actually a treasure trove of information on "...the use of coal-tar dyestuffs in lake-making, and in leather, fur, wood, paper, etc...." Fascinating.
