On [p. 338], the reference to “37. Scott to Conner, Mar. 16” seems a corruption for “164Scott to Conner”, which agrees with all other references to this source.

On [p. 486], a reference printed as “6 Memoir on Mex. finances.” most likely should be “61Memoir on Mex. finances. Sen. 19; 30, 1, pp. 2–4 (Scott).” There is a separate reference to that memoir in [note 2], using 61.

Also on [p. 486], the asterisk appearing in “Amer. Review, Jan., 1848, p. *2” is not explained.

In the Section A of the Appendix, the ordered list of numbered resources is missing #368. Nor are there any references to that number.
