    The table on page 1128 [omitted here] has been adapted from Letheby. The quantit ies given are some- what below the normal. The facts were collected from a number of sources, the ratio of children to adults being that adopted by Roderer and Eichhorn. My own experiments would lead me to give one pint as an average quantity of urine passed by chili Inn daily, up to the age of ten years, the quantity gradually increasing up to three pints in the adult. The solid constituents of the urine which, at the age of ten, are on an average 0.8 ounces daily, increase, according to my observation, up to 2.5 ounces in the adult. The quantity passed by girls and women is rather less than that passed by boys and men. The faeces passed by girls and women are consider- ably less than that passed by boys and men. The calculations in the table state the amount as less than one-third. My own observations, however, scarcely support these numbers. It would, I think, be more accurate to regard the frecal matters passed by female children and adults as about one-half that passed by male children and adults. The general showing of the omitted table is to the effect that, while there is two and a half times as mucli solid matter in the urine as in the faeces voided by an adult man, there is more than two and a quarter times as much in the voidings of persons of all ages and botl sexes, when taken in the proportion in which thej ordinarily exist in town populations. In these wastes, as in all others, the pure water con-
