In 1743 Edwards published the first volume of his "A Natural History of Uncommon Birds", the fourth volume of which appeared in 1751; three supplementary volumes, under the title "Gleanings of Natural History", were issued in 1758, 1760 and 1764. The two works contain engravings and descriptions of more than 600 subjects in natural history not before described or delineated. He likewise added a general index in French and English, which was afterwards supplied with Linnaean names by Linnaeus himself, with whom he frequently corresponded.
