Case-study design as printed: the author measured "two brothers", with initial measurements sometimes at birth, sometimes at the end of the first, second or third months. Height, weight, limb segments and head dimensions were measured with spring scales, tape lines, sticks and callipers.

"Having these things more or less in mind, I have attempted to take regular measurements of two brothers. The initial measurements were, in some cases, taken at birth and in others at the end of the first, second and third months."

For the first child, measurements covered "a period of six years and four months"; the second child's measurements were more frequent and regular over three years and four months. Both boys were reportedly normal, with only light colds and light measles attacks.

"They were, however, carefully made and extend from the end of the first month until the present time (January, 1930), a period of six years and four months."
