Gamma radiograph showing Roman joints in the arms of a figure. The type of joint used to attach the separately cast head cannot be determined in this radiograph. Gamma radiography was used due to the lack of available high-kV X-radiography. Thomas Ball (American, 1819–1911), Daniel Webster, 1853, sand cast probably after 1858, probably by the Ames Manufacturing Company, Chicopee, Massachusetts, H. 75.6 cm (Gilcrease Museum, Tulsa, inv. 0826.93). See fig. 213 for an overall view.
