specially frequented in ancient times, and whole districts were supplied from these favoured localities.

One of the most remarkable of these manufactories is that discovered by Dr Leveillé at Pressigny-le-Grand, in France, about half-way between Tours and Poitiers. Here there is an abundance of good flint of a honey colour, and of even, though coarse, texture. This flint was largely used in ancient times: the fields are covered with nuclei, flakes, etc.; and implements made here, and easily recognizable by the peculiar colour, have been found in various parts of France, and even, it would seem, in Belgium. I have in my collection a block of Pressigny flint, from which a flake more than 12 inches in length has been struck. The large nuclei of this form (fig. 85), which from their shape are known as "livres de beurre," have excited a good deal of discussion. They are generally from 8 to 13 inches in length, shaped more or less like a boat, with a broad butt at one end, tapering gradually to the other.
