Phila 1834 Key and Biddle. Very little spotting in text. Text lightly, evenly, browned but not particularly brittle. Original cloth-covered boards with paper spine label. Label is rubbed but largely legible.
Backstrip ends are chipped and worn down.
Cracking along outer hinges. Cover worn on all edges. Not easy to find in a fairly good original binding. Good, lightly foxed throughout, a bit worn. Thorough detailed technical survey of natural history of Alps.
