A 1691 Latin treatise on the hot springs of Bath, England, written by physician Thomas Guidott and printed in London at the author's expense for natural philosophers and physicians. Its copperplate plates show stone masonry, engraved coats of arms, a plan of a walled structure, and mineral deposit specimens drawn in fine hatched line, offering a designer historical scientific diagrams with dense, precise cross-hatching.
