Sir William Jackson Hooker (1785–1865) was an eminent British botanist, best known for expanding and developing the Royal Botanic Gardens at Kew into a leading centre of botanic research and conservation. At the age of nineteen he undertook an expedition to Iceland, his first outside Britain. Unfortunately, all his specimens and notes were destroyed in a fire on the return voyage (described in Volume 1), but he was able, with the help of the notes made by Sir Joseph Banks on an earlier expedition, to write this account. His work was first published privately in 1811, but a second edition was published in 1813 and is reproduced here. In 1809 England and Denmark-Norway were at war, and Iceland was a Danish dependency. Volume 2 offers Hooker's first-hand observations on the relationship between the two countries, and also includes detailed descriptions of the many volcanoes on the island.
