Retrieved May 31, 2013. Calhoun engaged William A. Weaver, the superintendent of the 1840 census, to review the figures and check them against related data from the 1830 census. Ibid. Weaver reported that he had examined "each specification of error" and concluded that the memorialists had themselves erred in their claims. While there doubtless had been minor errors, he said, there had been no glaring methodological mistakes as charged. See William Edwin Hemphill, ed., The Papers of John C. Calhoun: 1845, Columbia: Univ. of South Carolina Press, 1993, vol. 21, p. 156.
