Those persons who have attentively examined the interesting gallery of the _Histoire du Travail_ in the International Exposition of 1867, must have remarked a magnificent collection of these artistic productions of primeval ages. There were no less than fifty-one specimens, which were exhibited by several collectors, and were for the most part extremely curious. In his interesting work, 'Promenades Préhistoriques à l'Exposition Universelle,' M. Gabriel de Mortillet has carefully described these objects. In endeavouring to obtain some knowledge of them, we shall take as our guide the learned curator of the Archæological Museum of Saint-Germain. We have, in the first place, various representations of the mammoth, which was still in existence at the commencement of the reindeer epoch. The first (fig. 64) is an outline sketch, drawn on a slab of ivory, from the cave of La Madelaine. When MM. Lartet and Christy found it, it was broken into five pieces, which they managed to put together very accurately. The small eye and the curved tusks of the animal may be perfectly distinguished, as well as its huge trunk, and even its abundant mane, the latter proving that it is really the mammoth--that is the fossil--and not the present species of elephant. [Illustration: Fig. 64.--Sketch of a Mammoth, graven on a Slab of Ivory.] The second figure is an entire mammoth, graven on a fragment of reindeer horn, from the rock-shelters of Bruniquel, and belongs to M. Peccadeau de l'Isle. This figure forms the hilt of a poniard, the blade of which springs from the front part of the animal. It may be recognised to be the mammoth by its trunk, its wide flat feet, and especially by its erect tail, ending in a bunch of hair. In point of fact, the present species of elephant never sets up the tail, and has no bunch of hair at the end of it. A third object brought from the pre-historic station of Laugerie-Basse (M. de Vibraye's collection) is the lower end of a staff of authority carved in the form of a mammoth's head. The prominent forehead, and the body of the animal stretching along the base of the staff, may both be very distinctly seen. On another fragment of a staff of authority, found at Bruniquel by M. V. Brun, the cave-lion (_Felis spelæa_) is carved with great clearness. The head, in particular, is perfectly represented. Representations of reindeer, either carved or scratched on stone or horn, are very common; we mention the following:--
