A previous report1 demonstrated that the surface area proportions of the head, trunk, upper extremities and lower extremities are nearly constant in adults, and that in infants and children the proportions of these parts are different, varying with age until, gradually, adult proportions are assumed. The head, it was demonstrated, decreased from 18 per cent of the total area at birth to 6 per cent in the adult; the lower extremities increased from 25 per cent at birth to 38 per cent in the adult. The trunk and upper extremities varied less progressively. The extremes of variation from the average proportions of seventeen adults of various physical conformation were: head, +0.8 and -0.4; upper extremities, +1 and -2.9; trunk, +6 and -2.3, and lower extremities, +2 and -4.2.
The component parts of the upper extremities were: arms, 26 per cent; hands, 73 per cent; lower extremities: thighs, 50 per
