Philosophical transactions of the Royal Society of London
Philosophical Transactions of the Royal Society of London is a scientific periodical published in London by the Royal Society from 1666 for its fellows and natural philosophers. Its plates are engraved and manuscript-style diagrams: a ruled grid of numbered scales and angled lines, a long narrow survey sheet with plotted lines, a fan-lit doorway elevation with panelled doors, and a ridged landscape profile with a tiny row of trees, offering a designer precise technical line work, numerals and measured geometry.
