Sir John Richardson (1787–1865), surgeon, naturalist and Arctic explorer, went on Sir John Franklin's first two Arctic expeditions as ship's doctor and naturalist, and made observations and collected a large number of plant and animal specimens from the Canadian Arctic. On his return to England after the second expedition he began to write this four-volume work of natural history, first published between 1829 and 1837. A volume is dedicated to each of the classes of mammal, bird, fish and insect, which are found in the Canadian Arctic. This work is an interesting example of pre-Darwinian natural history, full of detailed descriptions of the appearance, anatomy and behaviour of the different species. Volume 2 was first published in 1831 and focuses on the species of birds found in the Canadian Arctic. It was co-authored with naturalist and illustrator William Swainson (1789–1855) and contains many illustrations.
