This is the second volume of a study alleging that the Treaty of San Ildefonso (1777) set the just boundary between Brazil and Uruguay at the Rio Ibicuí. If Brazil has expanded further, it has been through fraud, intimidation, and the connivance of Argentina. A secondary theme running through the second volume is that neither traditional party, blancos or colorados, can be fairly accused of surrendering to Brazilian imperialism.

Space does not permit discussing the merits of the main theses. However, this writer agrees that Professor Charles E. Nowell’s estimate of the first volume is applicable to both, “a useful résumé of the documentary evidence on the subject.” (HAHR, XXXVII, 109) One might add that there are some interesting maps in this book, and that the author is beating a dead horse.
