TitleUnpublished paper, 'On the colour of leaves of plants and their autumnal changes' by Arthur Hill Hassall
CreatorHassall; Arthur Hill (1817-1894); British physician; chemist; microscopist
DescriptionHassall writes: 'Chlorophyll, the name given by botanists to the green colouring matter of the leaves of plants, is not, as hitherto obtained, a simple substance, but is composed, in part at least, of constituents whcih are non essential to its green colour, though iron is deemed to be an indispensible ingredient.' Hassall shares experimental observations on chlorophyll.
