SELECTION OF PLUGGER POINTS ANDMALLETS. Plugger points exceeding seven-tenthsof a millimeter in diameter seldom shouldbe used for condensing cohesive better density and more speed maybe obtained by using large pieces of goldand a small plugger. It requires fortyten-pound blows of a mallet accompaniedby fifteen pounds of hand pressure on aplugger seven-tenths of a millimeter indiameter properly to condense one-thirty-second of a sheet of gold. The ideal wayto obtain this force is by a hand pluggerwith a hand mallet used by an force is applied with the fingersholding the plugger in the pen grasp.(Fig. 15.) This hand pressure partiallycondenses the gold and holds the toothtightly against the peridental membrane, WOODBURY. MANIPULATION
