Excerpt from book: The facts, therefore, respecting the excreta of a population of 10,000 adults may be thus tabulated : Table I.—Fcal Matter Passed Per 10,000 or Adult Population Per Diem. Pounds.

The quantities given are somewhat below the normal. The facts chapter{Section 4were collected from a number of sources, the ratio of children to adults being that adopted by Roderer and Eichhorn.

The solid constituents of the urine which, at the age of ten, are on an average 0.8 oz. daily, increase, according to my observation, up to 2.5 ozs. in the adult.
