Philosophical transactions of the Royal Society of London
Philosophical Transactions of the Royal Society of London, a 1675 journal issued in London by the Royal Society, a learned scientific body, for natural philosophers and men of science. Its pictures are small and plain: a decorated initial H, an engraved coat of arms within a scrolled frame, a foliate ornamental strapwork panel, and a geometric diagram of three circles labelled A, B, C, which a designer could borrow for initials, heraldic cartouches, or technical diagrams.
