George Field (chemist)

This obstacle, however, led him to consider the nature of its cultivation, and with a well-devised project he waited on Sir Joseph Banks for his advice, and, as he hoped, his co-operation.

Field continued his application of science to the purposes of the artist with good effect; his dexterity and care in the preparation of delicate colours set all competition at defiance.

Among his other inventions may be mentioned his metrochrome and his conical lenses, which produced a continuous rainbow with varied effects of refractions.

He bequeathed to the Royal Institute of British Architects six architectural drawings by J. L. Bond; to the Hanwell Lunatic Asylum ‘The Maniac,’ by R. Dawes, R.A.; while to the library of London University he gave a portrait of Dr. William Harvey, by Mirevelt.

Another professional treatise, his Rudiments of the Painter's Art; or, a Grammar of Colouring (London, 1850), was revised and in part rewritten by R. Mallet in 1870, and again in 1875 by E. A. Davidson, who added sections on painting in sepia, water-colours, and oils.
