PREFACE.
The following pages are the first two of the chapters of “Contributions to Practical Medicine,” as they stand in the fourth edition, 1904, of that book. They include my lectures on the causes and treatment of insomnia, in the necessarily colloquial style in which they were uttered. For the convenience of my professional brethren, these chapters now are offered to them in a separate form in this little book. Every word has been revised and many additions have been made, by the fruits of later experience, for the sake of clearness, completeness, and precision; this has been done with hope of usefulness in medical practice, and with the aim of accuracy in diagnosis and success in therapeutics.
