The Heaviest Part Of The Body

Bulk f u bulk the heaviest part of the body is tlie head. Not only are the bones constituting the skull more dense than those of any other portion of the skeleton, but the brain, wliich they protect, is, bulk for bulk, heavier than any other organ. The average weight of the alult human brain is 2.37 per cent of that of the whole body, but with the newborn child the proportionate weight is much greater, averaging 14.34 per cent. The relative weight of the entire skeleton to the body is 15.85 per cent., and that of its muscular investment 43.1. The heart, which keeps the whole human machine going, the motive power and support of vitality, bas, notwithstanding the immense amount of work it does and the muscular energy it has to bring to bear upon that work, merely a relative weight of 0.52 to the whole framework.
