These are probably to be explained by the different physiology of the new-born child and the adult. Most of the alkah in meconium is combined with sulphuric acid, and the latter is no doubt derived from the taurin of the bile, which is not absorbed as it is in extra-uterine life. Part also comes probably from the shed epithelium of the intestinal tract. The lower proportions of calcium, iron, and phosphorus can be explained by the greater need for these elements in the growing organism as compared with the adult. Ury has endeavoured to differentiate the inorganic salts and nitrogen excreted by the alimentary tract from those derived from the food, by comparing the proportions present in watery extracts of the fceces with those found in the whole stool, and these again with the urine :— Watery Total Fseces Per cent Total E.xcretion Extract of Fceces in Extract Urine Per cent in Urine Per cent in^^■atery Extract Nitrogen (N) Hydrochloric acid 1-051 3'2495 32-5 33-516 97-0 3-0 (HCl) Sulphuric acid (SO ) Lime (CaO) ..
