AUTHOR’S PREFACE.

The following pages contain an account of a long series of experiments made to determine the action of saline purgatives. Many of the results have been separately published in various scientific journals, and they are now gathered together with certain new material in an attempt to give as connected and complete an account as possible of the action of this class of drugs.

The experiments were begun at the suggestion of Professor Loeb, to whom I am greatly indebted for the constant interest which he has taken in the work, and whom it is a pleasure to thank for many helpful suggestions.
