Tome sixième.
A French technical volume titled Tome sixième, held by the Eisenbibliothek Schlatt, with no clear date or intended readership given in the record. Its single picture is a dense tabulated page of engine measurements comparing a Cornish-cylinder steam engine with a Boulton and Watt engine, set out in columns of loads, pressures and totals. For a designer it offers little beyond a raw grid of ruled cells and small serif figures, useful only as a texture or an example of dense nineteenth-century tabular typesetting.
