CONDITION NOTES: GOOD. End papers inscribed with owner inscriptions and calculations, and a short message on a back stub.  Occasional random pen marks in pages, though no underlining or notes.  All collated leaves present without major tears or creases, though original binder's blank leaves (possibly) missing on front, and a heavily inscribed blank stub at back.  Front cover joint split and holding on most, but not all, cords.  Head cap perished, tail cap complete.  All corners heavily rubbed with boards exposed and softened.
