For this reasononr operations with foil are much harderthan our gold inlays made of pure castgold; for this reason, also, we should bevery careful to use the correct lines offorce and the proper placing and step-ping of the plugger while condensingcohesive gold. A piece of flat gold willlie upon an anvil evenly, but if it isstruck in the center with a hammer, itcan never by any manner of malleting bemade to lie flat again. The same is aptto happen if we use cohesive gold in thinpieces, or go over it a second time. Weshould use non-cohesive foil whenever weare sure that it will be firmly held inplace, either by the walls of the tooth orby cohesive gold. The folds of gold slid-ing on each other not only allow us to uselarger pieces of foil, but they insure ourproducing a more perfect adaptationto the margin. For this reason, non-co-hesive gold may be used in
