The Tableland._ Apart from Villarino's journey on the Rio Negro in the eighteenth century, the first journey across the Patagonian tableland is that of G. Chaworth Musters, _At Home with the Patagonians_ (London, 1871). In the early volumes of the _Bol. Inst. Geog. Argent._ will be found the results of various explorations between 1878 and 1885 by Argentine travellers. With this group of documents, which provided the first material for his conclusions, we may associate the geological studies of Florentino Ameghino, "L'age des formations sedimentaires de Patagonie" (_An. Soc. Cient. Argentina_, l, 1900, pp. 109-130, 145-160, and 209-229; li, 1901, pp. 20-39 and 65-90; lii, 1901, pp. 189-197 and 244-250; liii, 1902, pp. 161-181, 220-249 and 282-342) and "Les formations sedimentaires du cretace superieur et du tertiaire en Patagonie" (_An.
