Formed matteraccumulates in the tissues as age advances, and thusinterferes with the free access of nutrient matter tothe bioplasm. As we grow old the proportion of the living to thelifeless matter of the organism becomes less and less,but even in advanced age and in the driest of growingtissues, living matter is still to be demonstrated inconsiderable amount, and can be discovered inadvanced age without difficulty.
