Among the witnesses examined by the Commissioners appointed to inquire into the constitution and government of the British Museum in 1847-1849 Augustus De Morgan was one of the more prominent, and his testimony contains some very interesting elucidations of bibliographical principles. It is to be found in the Report of the Commissioners . . . London, 1850, under questions 5704*-5816*, 6481-6528, and 8966-8967, being p. 375-384, 425-431, and 591-595 of the Report. Part of his testimony has been reprinted by Mr. Frank Campbell in his The theory of national and international bibliography, . . . London 1896, p. 279-291.
