I am privileged to publish here a few very interesting fragments of Acropolis vases, the paintings of which are executed wholly or partially on a white ground. Naturally the number of these fragments is comparatively small, but they are of greater interest than those of black-figured or red-figured technique, as enlarging the somewhat meagre list of extant specimens of this class. When I last had the opportunity of examining the collection, before it had been removed from the Acropolis and undergone the systematic sorting so ably performed by Drs. Wolters and Graef, and subsequently by Dr. P. Hartwig, there were portions of fourteen vases, the majority of which were kylikes, a few having the white ground on both sides of the vase but most of them showing a combination of a plain varnished or a red-figured exterior with interior scenes painted on a white ground, or even a white slip outside and of work within. Inasmuch as the whole collection has now been worked over, it is not worth while to enumerate the total, as it appeared some years ago. In the case of the most interesting vase, which now appears for the first time (Plate X.), I have reason to believe that all extant fragments are included in the Plate, several additional drawings having been executed by M. Gilliéron, whose work, it is needless to say, is characterized by its usual admirable fidelity.
