In addition to these works we have the recent researches of Marsh, who has completed to an extraordinary degree our knowledge of the genealogy of the genus Equus, by numerous discoveries (fig. 117) in America (Wyoming, Green River, White Hirer). The eocene Orohipjjus, in which the small posterior toes were present as well as the three principal toes which rested on the ground, was succeeded in the Lower Miocene formation by Anchitherium with three hoofs ; and the latter was followed by the Hipparion of the Pleiocene formations; and this is the ancestral form of the existing genus Equus. The origin of most orders of Mammalia, such as Rodentia, Cheirop- tera, Proloscidea, Cetacea, etc., cannot be clearly traced out, but for certain orders, as the Prosimice, Carnivora, Ungulata, and Jio-.
