First edition, first printing. 604pp, with tables, diagrams etc in text. Orange cloth-covered boards with black titles front and spine. 8vo. Cloth a little tired, slightly soiled around extreme edges, gently rounded at spine tips. A little spotting on text block edges and endpapers else internally neat, clean, bright and tight. A small fault in manufacturing at pp12-13, resulting in minor misfold on paper at base of gutter.
