Abstract
ALTHOUGH it is not the purpose of this paper to consider in detail the general factors that as a rule affect equally the growth of both limbs, a few words about normal growth may not be amiss.Nature produces regularly in the human being, as in many other animals, paired, symmetrical, mirror-imaged extremities of essentially identical length. These normal growth processes are complex and dynamic, beginning with the union of an ovum and a sperm, which carry in their chromosomes the hereditary factors (genes) that determine whether the person will have the muscular legs of an athlete, the shapely limbs . . .
