Caption title.
John Clark (ca. 1725-ca. 1790) was an optical instrument maker, jeweller, and goldsmith whose shops were located in Edinburgh between 1749 and 1796.  "He was the second earliest Scottish microscope maker (John Finlayson was the first in 1743) and produced high-quality instruments that optically were much better than compound microscopes at the time.  Clark first offered microscopes, made in silver, for sale in 1749, subsequently modifying their design in 1754, and ultimately advertising a brass instrument in 1773. John Clark had at least three shops: one at James Gilliland's Jeweller, at the upper-end of the Luckenbooths (1749); one at Parliament Close (1751-1755); and one at Sir Isaac Newton's Head... (1773-1782)."--Catalogue of the The Golub Collection, University of California, Berkeley.
