A line was inadvertently dropped from Antoni Malet's review of Galileo's Diálogo sobre los dos máximos sistemas del mundo, on p. 92 of the March 1996 issue. ‘Italian candido, for white, turned into Spanish cóncavo (p. 204)’ should read: ‘Italian candido, for white, turned into Spanish cándido (p. 73) or concavo, for orb or orbit, into Spanish cóncavo (p. 204)’. We apologize for this oversight.
