D. J. M., March 23, June 3, And June 7, 1910

In this series of 3 experiments, 221 grams, 398 grams, and 376 grams of cream, respectively, were taken. The subject was not especially satisfactory, as he was inclined to be restless; it is particularly unfortunate, therefore, that he should have been selected for this study in which so slight an effect upon the metabolism would be produced as with cream. Hence the three experiments can be treated only in a general way and discussion of the individual periods is unjustifiable. The results of the experiments are given in tables 188,189, and 190. From an examination of the data it is seen that there was no positive increase in any of the factors measured in the experiment of March 23. In the experiment on June 3 there was a total increment of about 4 grams in carbon-dioxide production, 11 grams in oxygen consumption, and 20 calories in heat production. Similar increases in the first two factors are seen in the experiment of June 7, but not in heat production. The detailed pulse records (not given in the tables) show very little increase in the experiment of March 23, but in the experiment of June 3 there was a change from an average of 63 in the preliminary period to an average of 69 after food. A similar change in the pulse rate occurred in the experiment of June 7.
