A philosophical essay: declaring the probable causes, whence stones are produced in the greater world ... Being a prodromus to a medicinal tract concerning the causes, and cure of the stone in the kidneys, and bladders of men
A 1672 London philosophical essay by physician Thomas Sherley, printed for William Cademan, on how stones form in nature and a prelude to a treatise on kidney and bladder stones, written for a learned readership. The three pictures are printer's ornaments and a decorated initial, not scientific diagrams: a cherub-and-scroll border, a grotesque central cartouche, and a woodcut initial O with a leafy design beside running text. A designer could draw on their symmetrical scrollwork, putti and foliate letterforms for historical borders and capitals.
