A manual for managers, designers, weavers, and all others connected with the manufacture of textile fabrics, containing definitions, derivations and explanations of technical terms, the use made of many substances; rules, tables, and some elementary instructions for beginners
Alfred Spitzli's 1881 technical manual, published in West Troy, New York, for mill managers, designers, and weavers, defining trade terms and listing materials, rules, and tables for the textile industry. The plates are small wood engravings of inspection equipment—compound microscopes, pocket magnifiers, retort stands, and a lamp—drawn in fine parallel hatching with maker names lettered on the bases and catalogue numbers below, useful as isolated instrument silhouettes or ruled-tone shading references.
