Contrary to what is said in some of the older textbooks, growth in height does not proceed by fits and starts, nor does growth in upward dimensions alternate with growth in transverse ones. The more carefully measurements are taken, with precautions, for example, to minimize the decrease in height that occurs during the day for postural reasons, the more regular does the succession of points in a graph of growth become. Many attempts have been made at finding mathematical curves that fit, and thus summarize, human growth data. What is needed is a
