Method Primary source abstract: "The body of the second lumbar vertebra was obtained from 95 apparently healthy subjects and from 14 clinical cases of osteoporosis. For the purposes of this investigation “children” were defined as individuals under 17 yr. Each vertebra was trimmed of surrounding tissue and the neural arch was sawn off flush with the body. The volume of the body was then measured by water displacement. It was next Cut into four or five coronal slices."
Comments P.1914 left column top paragraph: "Within the axial skeleton, the rate of marrow conversion is more gradual and continues into and throughout adulthood. The relative proportion of red marrow decreases by nearly half between the 1st and 8th decades, from 58% to 29% (primary source)."
