I have included here a copy of the Mezzotint of John Bird, Engraving by Valentine Green, after Lewis, published London, 1776.

John Bird was an accomplished and well-known optical and instrument maker, worked in London from 1740 until 1763. He worked for the great clockmaker George Graham. William Wales,  astronomer on James Cook's voyages, records a barometer and thermometer used on the voyages. An example of his work is in the Museum of History and Science at Oxford.
