Saussure's views on linguistic geography are not-as the position of the chapter entitled 'Linguistique géographique' in the Cours de linguistique générale might appear to suggest-a mere appendage to his proposals for the science of linguistics. On the contrary, they constitute an important part of Saussure's argument and must be seen in the context of the debate about the work of Gilliéron in the early decades of the 20th century. © 1993.
