Abstract

Hutton made a geological collection to illustrate his theory of the Earth, and frequently cited phenomena displayed by specimens in it to support his arguments. His followers also considered that the evidence provided by the collection would help to establish his views. After Hutton's death it was given to the Royal Society of Edinburgh which, however, under the terms of its charter, was obliged to lodge it in the Natural History Museum of the University. The Museum's curator, the Wernerian, Robert Jameson, thought the collection of little account, and neither displayed it nor kept it together. By the mid-1830s most of it had been dispersed or thrown away, and nothing is known of it since. The list of specimens compiled by its first trustees has also disappeared. By piecing together information in Hutton's writings and letters, and in those of his friends, we learn something about the contents of the collection and how it was formed, and also add to our knowledge of his acquaintance. The final section of the article brings together all Hutton's descriptions of his rocks and minerals and, in doing so, demonstrates the weight of proof that he rested on careful visual analysis of hand specimens
