In thecase of two adjacent cavities one should befilled and finished before the filling of the otheris begun. To fill either cavity : Place a large pellet orcylinder of semi-cohesive gold in the linguo-gingival angle so as to reach the axial wall whileprotruding beyond the enamel. With a holdinginstrument in the left hand and such a pluggeras No. 5 or No. 6, Fig. 442, in the right, pack thegold into the angle and against the bevel of themargin by hand pressure. Place over thisanother piece of semi-cohesive gold coveringabout equally the axial, lingual, and gingivalwalls, and pack it into place, but do not en-tirely condense it. Next apply a smaller pelletof annealed gold against the central part of thelast piece, and with a small point, such as No. 1,thrust the annealed gold so as to force thesemi-cohesive gold ahead of it into the few
