PREFACE.

The present article is intended to be one of a series dealing with the functions of different parts of the cerebrum, more particularly with the so-called association areas. The publication of the present work has been considerably delayed, owing to the pressure of other duties, but it is hoped that the second article of the series, dealing with the parieto-occipito-temporal association area, will be ready

soon.

The experiments contained in this monograph were made at three institutions: The Harvard Medical School, the Dartmouth Medical School, and the McLean Hospital. I am under obligation to the officers of these institutions for assistance and advice in many ways.

An account of the experiments on cats has been previously reported in the American Journal of Physiology, and for permission to republish part of this work I am indebted to the editor, Dr. W. T. Porter.

A grant from the Carnegie Institution to the author, as research assistant, made it possible to continue the investigation of the functions of the association areas, and to extend the work to include experiments upon monkeys. I take this opportunity to acknowledge the aid thus rendered and to express my sense of obligation for it.
