In the course of his research among the so-called 'southern Slavs', carried out between 1872 and 1913, Baudouin de Courtenay (BdC) collected a large amount of dialectological texts he only managed to ...publish partly. According to his view of linguistics, these texts had to be generalizations both on the dialectological-ethnological aspect and on the purely linguistic one. The first two volumes of materials, dedicated to the Resian (BdC 1895) and to the Torre dialect/tersko (BdC 1904), fulfill the above first aspect, while the lexicographic repertoires, ie the Resian Dictionary and the Torre dialect Glossary, should have answered the second. Unable to achieve the latter part of the project, Baudouin left the task to others, in fact, for generations to come. Today, after more than a century, the Glossary has seen its light (Spinozzi Monai 2009), offering the possibility, among other things, of its comparison with the Materials ii. This paper intends to detect significant differences that emerge from this comparison and at the same time the substantial complementarity of the two works.
