The mass is not tendereven on firm pressure. There is dull-ness over it, but not complete patient notices that the mass changes in position as she moves about, and when she sits up itmoves far down into the abdomen, while when on her back it isfrequently beneath the right ribs. When this mass is out frombeneath the right costal margin the right kidney can not be felt,nor on the left side, on the deepest inspiration, could the kid-ney be palpated.
