> Chapter 12, p. 232, Hayek writes, "There was even an economist among the
   contributors to the first volume of L'Industrie, St. Aubin, although one
   whom J.B. Say unkindly described as 'the clown of political economy'."
   Does anyone know who St. Aubin is, and where Say said this about him? <

The publications of Camille de Saint Aubin (also known under the pseudonym Nibuatnias) can be found in the catalogue of the Biblioth???que National de France.

About the input of Camille de Saint Aubin in Saint-Simon's *Industrie*, see the "avant-propos" of Vol. XVIII of the *Oeuvres de Saint-Simon & d'Enfantin* (which corresponds to Vol. II of the *Oeuvres de Saint-Simon*), in particular on p. 10-11 and p. 15, n. 1 [This edition can be consulted online via the Gallica website of the Biblioth???que National de France.]

Saint Aubin is also mentioned in Luc Marco, "From the dynamics of the entrepreneur to the analysis of the firm. La science des affaires, 1819-1855", in: Gilbert Faccarello (Ed.), *Studies in the History of French Political Economy. From Bodin to Walras*, London, Routledge, 1998, pp. 284-318, more specifically on p. 312, n. 24.
