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 sec-

ond portions, devoted respectively to the development of the senses and of

the will. The present volume contains the third part, treating of the devel-

opment of the intellect; and three appendixes are added containing supple-

mentary matter.

Professor Preyer considers that the development of the power of using lan-

guage is the most prominent index to the unfolding of the intellect. He dif-

fers with Professor Max Mueller, however, on the question whether the op-

eration of thinking can be carried on without the use of words (see the recent

elaborate work of the latter on "The Science of Thought").

At my suggestion, the painstaking translator of this book has prepared a full

conspectus, showing the results of Professor Preyer's careful observations

in a chronological order, arranged by months. This considerable labor will

render the book more practical, inasmuch as it will enable each reader to see

at a glance the items of development of the child in the several departments

brought together in epochs. This makes it possible to institute comparative

observations under the guidance of Professor Preyer's method. I think that

I do not exaggerate the value of this conspectus when I say that it doubles

the value of the work to the reader.
