Scientific American, Vol. 34, No. 23 (1876)
Scientific American, volume 34, number 23, a weekly American periodical of 1876 aimed at inventors, engineers and general readers interested in mechanical science. Its pictures are wood-engraved mechanical drawings of presses, tools and machines, with some crowded exhibition scenes; a designer could take from them the clean line structure of Victorian machinery and its numbered, labelled diagram conventions.
