My quotation from Galiani's _Dialogues on the Grain Trade_ was downloaded 
from the Bibliotheque Nationale de France 
http://gallica.bnf.fr/ark:/12148/bpt6k88409r.  There are two other works by 
Galiani there: _De' doveri de' principi neutrali verso i principi 
guerreggianti, e di questi verso i neutrali_ [Reprod. de l'ed. de, [Milan] : 
[s.n.], 1782] and _Opuscules philosophiques et litteraires, la plupart 
posthumes ou inedites_ [with Simon-Jerome Bourlet de Vauxcelles, Paris : 
Impr. nationale, 1796].  In engish there is a translation of the seventh 
dialogue [my quotation was from the 8th dialogue], in the collection 
_Commerce, Culture, and Liberty: Readings on Capitalism Before Adam Smith,_ 
ed. Henry C. Clark (Indianapolis: Liberty Fund, 2003) electronically 
available from .THE ONLINE LIBRARY OF LIBERTY at

Galiani was witty, sarcastic, vitriolic, and sometimes outright obscene, in 
his criticism of the Physiocrats.  See, e.g., F. Steegmuller: A Woman, a 
Man, and Two Kingdoms : The Story of Madame D'Epinay and the Abbe Galiani 
[Knopf, 1991].   Only Voltaire was better (L'homme aux 40 ecus).

I fully agree with Alain Alcouffe that the Britannica entry is totally 
unfair to Galiani.
