The nutrient enema.

Since Voit and Bauer (1869) published their observations on nutrient enemata, numerous papers have been written dealing with the question of absorption from' the rectum.' As yet, no unanimity of opinion exists regarding their value. In recent years, few contributions to the subject have been made. The present paper is a report of investigations performed with three of the more important substances which are commonly used in nutrient enemata, namely, glucose, normal saline and predigested protein.
