PERILS OF PRECOCITY.
Baillet mentions one hundred and sixty-three children endowed with extraordinary talents, among whom few arrived at an advanced age. The two sons of Quintilian so vaunted by their father did not reach their tenth year. Hermogenes, who at the age of fifteen taught rhetoric to Marcus Aurelius, who triumphed over the most celebrated rhetoricians of Greece, did not die at an early age, but at twenty-four lost his faculties and forgot all he had previously acquired. Pico di Mirandola died at thirty-two; Johannus Secundus at twenty-five, having at the age of fifteen composed admirable Greek and Latin verses and become profoundly versed in jurisprudence and letters. Pascal, whose genius developed itself when ten years old, did not attain the third of a century. In 1791, a child was born at Lubeck, named Henri Heinneken, whose precocity was miraculous. At ten months of age he spoke distinctly, at twelve learned the Pentateuch by rote, and at fourteen months was perfectly acquainted with the Old and New Testament. At two years he was as familiar with geography and ancient history as the most erudite authors of antiquity. In the ancient and modern languages he was a proficient. This wonderful child was unfortunately carried off in his fourth year.
