In the experiments herein described, data were obtained concerning the influence of morphine and ether, separately and together, on the function of the kidneys, that is, on the rate and composition of the urine secreted. It has been known for a long time that anesthesia diminishes the volume of urine secreted, and data exist also concerning the effect of anesthetics on metabolism in general, as represented by the composition of the urine, but we were unable to find a detailed study of the effects of anesthesia on the function of the kidneys.
