Not illustrated. 1897 edition. Excerpt: ... stood in the laboratory for some time previously to its being boiled for the experiment. The stomach contained 2436 grams of fat acids, 'i.e., l8'7S per cent. of the total fat was present in the stomach as free fat acids. The percentage of the neutral fat had diminished, while the percentage of the fat acids had increased. The fat acids, combined as soaps in the stomach, remained exactly the same as the quantity originally given, but since the percentage had increased from 0'06 to 0'10, it is not at all likely that that alone of the components of the total fat had wholly remained in the stomach, so that we may consider that this case is no exception, and that the stomach formed not only fat acids but also soap. In the small intestine only 0'97? gram of fat was found, and since no less than 9'836 grams had passed through the pylorus during the period of digestion, either 8859 grams had passed on into the large intestine or had been absorbed. The total fat contained only 0349 gram as neutral fat, so that the percentage had fallen to 35'85 per cent. (the milk given contained 96'69 per cent.). The free fat acids amounted to O'608 gram, that is 62'19 per cent. of the total fat. As originally the milk only contained 3'25 per cent. of fat acids, we can conclude that no less than 5894 per cent. of the neutral fat had been converted into fat acids in its passage as far as the caecum. The fat acids present as soaps had increased to 002 gram, which raises the percentage of fat acids present as soaps to no less than 2'06, an amount which closely resembles that present in the foregoing case. In the large intestine we unfortunately cannot follow the changes were lost in the process of separation. We, however, see that only 0402 gram of the more
