Third edition, revised, published in 1884. Beautiful quality book - bound in leather with the emblem for the royal indian engineering college embossed in gold on the front, marbled edged pages, 1885 bookplate for the college on the pastedown. The front cover board has become loose, otherwise the binding is superb. some other wear and rubbing to the cover, and age browning to the pages.
