When a multitude of facts are taken into account, thei^e.

There are two points that are very far from being deter-mined : the one the fate of the products of digestion; the otherthe exact limit to which digestion is carried. How much—e. g.,of proteid matter—does actually undergoconversion into peptone; how much isconverted into leucin and tyrosin; or,again, what proportion of the albuminousmatters are dealt with as such by the
