By this instrument, it is shown that there is relativity be-tween composition and shrinkage; the heavily tin alloys makeamalgams which shrink most notably. If to these alloys goldor copper is added, the shrinkage is lessened in approximatelyj List relation with the amount of non-shrinkers introduced! But it is to the measurement of the amalgams made fromthe heavily silver, tin, and copper; and silver, tin, gold, andcopper alloys that we are now most attracted; for shrinkagein connection with these is reduced to team rifle-practice. For this purpose, I now use the two-inch matrix — micrOmetric — and direct microscopic
