Continuatio epistolarum, datarum ad longè celeberrimam Regiam Societatem Londinensem
A 1696 Latin edition of Antoni van Leeuwenhoek's letters to the Royal Society of London, published in Leiden by Cornelis Boutesteyn for natural philosophers and microscopists. Its plates are engraved diagrams of microscopic structures labelled with letters, such as a lens-like section, a shelled form, a cellular ring, and a tissue sketch, drawn in fine parallel hatching and dotted stipple. A designer could borrow their precise labelled-diagram style, the crosshatched shading, and the clean spacing of lettered callouts.
