Cunningham, a physician, was naturalist aboard the Nassau, a steamer sent to survey the Strait of Magellan and the adjacent channels. This book contains a narrative of the voyage and natural history descriptions. Cunningham’s own interest was in the ornithology of the region, but he also discussed the botany of the area, mentioning his collections of plants in the Royal Herbarium, Kew, and promising articles on the reptiles, amphibia, fishes, mollusca, and crustacea in Linnean Transactions. He acknowledged the help of Hooker, Huxley, Newton, Flower, Sclater, Salvin, Gray, Gunther, and Baird.
