Body volume was measured on 14 male adults at 7 intervals during a 24 hour period using a water displacement technique. The variation in body densities fell within the accepted limits of error propagated by the technique. Body densities were also performed on 173 male adults ranging between the ages of 17-69. Values were effectively ranked in terms of age and body fat, demonstrating a continued increase in body fat with an increase in age. These values were independent of body weight. The human body volumeter is a simple, rapid and effective device which compares favorably with the underwater weighing technique for estimating body density in large populations. The precision for estimating body fat is 0.488 kg when the residual lung volume is measured but is reduced to 1.52 kg when the volume is estimated.
