The laboratory, or, School of arts : containing a large collection of valuable secrets, experiments, and manual operations in arts and manufactures ...
The Laboratory, or School of Arts is a 1799 London technical compendium compiled by Godfrey Smith, printed by C. Whittingham for several booksellers, and aimed at tradesmen and home experimenters seeking recipes and manual processes. Its copperplate plates show sundials, optical instruments and small mechanical setups with precise line-engraved fig-numbered diagrams that a designer could use for clean technical linework and labelled schematic layouts.
