One of the cases was a child who at birth resembled an ordinary infant of five months.

From four to fifteen months his penis enlarged, until at the age of three it measured when erect 3 inches.

At this age he was 3 feet 7 inches high and weighed 64 pounds.
The last case mentioned was an infant who experienced a change of voice at twelve months and showed hair on the pubes.

At three years he was 3 feet 4 1/2 inches tall and weighed 51 1/4 pounds.

Smith, in Brewster's Journal, 1829, records the case of a boy who at the age of four was well developed; at the age of six he was 4 feet 2 inches tall and weighed 74 pounds; his lower extremities were extremely short proportionally and his genitals were as well developed as those of an adult.
