Except that found at Notre Dame d'Or, as already mentioned, it is the only mould Avith which I am acquainted designed to cast palstaves or celts of Mr. Du Noyer's fourth class.

The two parallel ridges which ]u-oject from the upper part, and the transverse ridge which unites them at the base, aiford space for the cavities, which were designed to produce the corresponding ridges in the celt itself, the transverse ridge representing the " stop- ridge " of the celt. In the inside view we observe at the top an hemispherical cavity, into which the metal was poured. Immediatoly below tliis cup-hke cavity, and between the two parallel cavities designed to form the lateral ridges of the celt, we see a portion of the mould occupying the same space which would be occupied in the manufactured celt by VOL.
