Philosophical transactions of the Royal Society of London
The Philosophical Transactions of the Royal Society of London, published in London from 1666, was the learned society's journal of scientific papers, issued for natural philosophers and men of science. Its folding copperplate pages show geometric solids and optical diagrams, with crystal forms drawn as hexagonal prisms, pyramids and cut shapes in fine black line, useful to a designer for technical line work, schematic layouts and diagram plates.
