A practical treatise on cast and wrought iron Bridges and Girders, as applied to railway structures, and to buildings generally, with numerous examples, drawn to a large scale, selected from the public works of the most eminent engineers
A practical engineering treatise by William Humber, published in London by E. & F. N. Spon in 1857, aimed at railway engineers and builders who needed large-scale drawings of iron bridges and girders. Its plates show elevations and sections of railway viaducts, lattice girders and a circular cast-iron framework, drawn in clean line with dimensions and lettering. A designer could take from them the rhythm of repeated arches, the diagonal bracing of lattice trusses, and the radiating spokes of a wheel-like structure as graphic motifs.
