A piece of liver is used as control. if the liver bit floats, the test has no meaning, it is clear that putrefaction has set in. If all the pieces of lung float, they are crushed under a weight and tested again. floatation is positive when the baby has respired. But if the piece sink after pressure, no respiration has taken place. if some piece float while otherb sink, it mean feeble respiration taken place.
