Fig. 173 represents a simple apparatus used for rolling and cuttingthis description of lozenges. Among the recent inventions is aglass roller of considerablestrength and durability, de-signed for rolling out pastry;being open at both ends, itmay be filled with warmwater and securely corked;in this way a temperature ismaintained favorable to thesoftness and tenacity of themass. It is well adapted touse in making lozenges. Theroller shown in the cut isof hard wood. The rolling-board IS adjusted as tOllOWS: Board, roller, and punch, for making lozenge*. Fig. 272 CONSEKVES, CONFECTIONS, ETC. Having a punch of a certain diameter, a small portion of the mass isrolled and cut out, and its weight ascertained; if it be too heavy, thecake is rolled thinner, and so on until adjusted to the required weight;a strip is now tacked on to each side of the board, within the rangeof the roller, and corresponding in thickness with the cake, so thatthe roller, when passed over, will reduce the medicated mass to theright point. A board arranged in this way should be kept for eachkind of lozenges, as the weight of different materials varies, and, inadjusting it, a small allowance must be made for the moisture presentin the soft mass, which increases its bulk. In dividing a mass extem-poraneously, it is convenient to roll the whole out into a square oroblong cake of suitable size, and then, with a spatula, divide it equallyinto a definite number of rectangular masses. Some manufacturers have, independently of their cutting punche
