Arcana naturae detecta
Antoni van Leeuwenhoek's Latin collection of microscope observations, published at Delft by Henrik van Kroonevelt in 1695 for scholars and correspondents of the Royal Society. Engraved plates group lettered figures on open white pages: insect anatomy, seeds, hairs, branching vessels in tissue, and microscope parts, useful for scientific diagram layouts, keyed labels, and fine stipple and line shading.
