1869, xii, 180pp, profusely illustrated, including twenty folding diagrams at the end. The title page is darkened as though a newspaper clipping might have been inserted there, the rest of the pages have no foxing. None of the diagrams seems to be missing, but there are two drawings designated as Drawing D, one in the text, one at the end, which are different. There are problems throughout the text designating the various drawings, (perhaps a mechanical engineer could figure it out). Extremities worn, outer hinges split, bottom 1.5 inch of backstrip lacking, else Fair, contents G. Should be rebacked or use as a working copy.
