The experiment with A. H. M., December 5 to 6, 1906, was fully discussed in a previous section in which the basal metabolism was considered. Although originally planned for a 24-hour experiment, it was soon apparent that the effect of ingesting oil could be found only by studying the results obtained in the periods immediately following the taking of the mayonnaise; hence the results of the experiment have also been computed on both the 12-hour and the 8-hour basis. These results are given in tables 19, 20, and 21.1 From the figures given in these tables, one may conclude that the effect of olive oil upon the metabolism is slight.
