the edges) a piece of cardboard of the same size is inserted to make the expanse of the linen stiff and secure as a cover for the chalice. Yet, it is most fitting that the material of the pall should be altogether congruous with its origin, and consist of a strip of linen, about as long as the width of the corporal, folded up in one square, stitched at the edges, and stiffened with starch. The size of the pall should not exceed the diameter of the paten.
The purificator is a piece of fine white linen about thirteen inches square, hemmed with a narrow hem, and having a small equal-armed cross embroidered in white thread in the middle. The purificator is folded in three parts lengthwise, i. e., one-third folded over the central third, and the other third part folded over upon the double fold.
The veil, which should be made of silk, may be about twenty-four inches square, and thus large enough to cover the chalice and paten and touch the corporal on all sides; yet it will suffice if the veil be not more than sixteen or eighteen inches square, and cover only the anterior part of the chalice. For material, a silk that is light in weight, and which will fall in graceful folds on all sides, and not over burden the pall, is to be preferred. Stiff and heavy silk, and heavy embroidery are most undesirable in a chalice veil. For ornament a small equal-armed cross may be embroidered in the centre of the veil, or a somewhat larger one in the centre of that part which hangs in front of the chalice.
The burse is a case in which the corporal, folded, is kept when it is not in use upon the altar. The burse should be about eight or nine inches square, and be made of two squares of card-board covered on one side with silk, and on the other (the inner when made up) with white linen. These two parts are stitched together on one of the four sides; and the edges which are at right angles with the same stitching are connected by flexible linen folds, so as to allow the unfastened edges to open to a width of about three inches. One of the outer sides of the burse may be ornamented with embroidery.
Where coloured vestments are used the burse and the veil will agree in colour with the silken vestments of the priest; otherwise they may always be white.
