Abstract
The 9 determinations of surface area on 3 children from 2 to 5 years reported in the first paper of this series, are not sufficient to warrant the computation of a formula for surface area at this age level but their relation to the trend of previous determinations by other methods on both living and dead may be determined.
A preliminary survey of the literature furnished 135 actual determinations of the surface areas of normal individuals who ranged from birth to late maturity in age and whose heights and weights were given. The minimal body weight in this series was 2.5 kg. The sources and methods are as follows: Fubini and Ronchi, 1 1 living adult, geometric method; Meeh, 2 16 living males, 6 days to 66 years, coating and geometric method, Ssytscheff, 3 23 males and females, 15 days to 43 years, coating method; Lissauer, 4 8 male and female cadaver, 28 days to 15 months, coating method; Lassablière, 5 15 determinations each based on averages of 2 or 3 living children, one day to 24 months, geometric method; Pfaundler 6 (including Costner), 14 infant cadavera from one-fourth month to 18 1/2 months, coating method; Du Bois et al., 7 , 8 8 living males and females, 12 to 32 years, 1 female cadaver, 21 months, coating method; Wörner.” 16 living males and females from 5 to 50 years, coating method; and Frontali, 10 33 living boys and girls from 24 days to 12 years, integrator method.
The trend of increment of surface area of these cases with body weight is shown in Fig. 1. This trend has been fitted by 2 variations of the method of least squares. The first expression is:
