There are two points that are very far from being deter^ mined: the one the fate of the products of digestion; the other the exact limit to which digestion is carried. How much—e. g., of proteid matter—does actually undergo conversion into peptone; how much is converted into leucin and tyrosin; or, again, what proportion of the albuminous matters are dealt with as such by the in- testine without conversion into peptone at all, eithtr as soluble proteid or in the form of solid particles ? 1. It is generally believed that solu- ble sugars are absorbed, usually after conversion into maltose or glucose, by the capillaries of the stomach and intes- tine. 2. There is some positive evidence of the presence of fats, soaps, and sugars in unusual amount after a meal in the por- tal vein, which implies removal from the intestinal contents by the capillaries, though, so far as experiment goes, the fat is chiefly in the form of soaps, Certain experiments have been made.
