EDITOR'S PREFACE.

This second volume contains the further investigations of Professor
Preyer on the mind of the child. The former volume contained the first
and second portions, devoted respectively to the development of the
senses and of the will. The present volume contains the third part,
treating of the development of the intellect; and three appendixes are
added containing supplementary matter.

observations in a chronological order, arranged by months. This
considerable labor will render the book more practical, inasmuch as it
