With so large a number of respiration experiments, it seems needless to discuss them individually; hence only the statistical data are given here, grouped according to the carbohydrate used, with the idea of including the results later in general summary tables and discussing not only the influence of the individual carbohydrates upon the basal metabolism, but likewise the effect of variations in the amounts ingested. The preliminary experiments with the universal respiration apparatus on the influence of the ingestion of food were made with the cooperation of Professor Otto Cohnheim, formerly of Heidelberg, who kindly volunteered as a subject while he was a guest of the Nutrition Laboratory in the fall of 1909. The details of the experiments with Professor Cohnheim are given in tables 154 and 155. The details of the whole series of respiration experiments following the ingestion of carbohydrates are given in tables 126 to 168. Statistical data not included in the tables are given in the following pages for a number of the experiments. When no further data are available, no mention is made of the experiment in the statistical text.
