The second is composed of the 'leaf' types, which are solely characteristic of the Solutrean and which degenerate and entirely disappear at its close; these latter are the arrow and lance head forms, many of which are fashioned with a rare degree of perfection and exhibit the beautiful broad Solutrean retouch across the entire surface of both sides of the flake, together with perfect symmetry, both lateral and bilateral; they are commonly known as the willow-leaf (narrow) and the laurel-leaf (broad) forms. The explorers of the type station of Solutré have discovered five principal shapes, as follows: (1) irregular lozenge; (2) oval, pointed at both ends; (3) oval, pointed at one end; (4) regular lozenge; (5) arrow-head form with peduncle, doubtless for attachment to a shaft. The perfected Solutrean laurel-leaf spear heads do not reappear in any other Upper Palæolithic period, but their resemblance to Neolithic flints is very marked. The 'willow-leaf' spear heads (_pointes de saule_), chipped on only one side, characteristic of the _early Solutrean_, may possibly be contemporary with the closing Aurignacian culture of Font Robert. At Solutré layers have also been discovered rich in bone implements and in graving-tools, as well as small 'laurel-leaf' points worked on only one face. As regards the general tendencies of the early Solutrean culture in Dordogne, at the Grotte du Trilobite (Yonne), and in Ardèche, there is a marked decline in the work in bone and in the variety and workmanship of all the implements, excepting only that of the primitive flattened spear heads, made of flakes, retouched in Solutrean fashion, but on one side only. Typical deposits of early Solutrean culture are found at Trou Magrite, in Belgium, at Font Robert, Corrèze, and in the third level of the Grotte du Trilobite, Yonne; in the second level we find flints with the nascent Solutrean retouch. The distinctive implement of the 'high' or _middle Solutrean_ is the large 'laurel-leaf' point, flaked and chipped on both sides and attaining a marvellous perfection in technique and symmetry. The finest examples of these spear heads are the famous _pointes de laurier_, fourteen in number, discovered at Volgu, Saône-et-Loire, in 1873: they were found together in a sort of cache and, it would seem probable, were intended as a votive offering, for one at least was colored red, and all were too fragile and delicate to be of any use in the chase. They are of unusual size, the smallest measuring 9 inches, and the largest over 13-1/2. In workmanship they are equalled only by the marvellous Neolithic specimens of Egypt and Scandinavia.
