    On these four days the uriue became alkaline both after breakfast and after dinner; and the effect of dinner is ob- served to be more intense, as well as more enduring, than that of breakfast. In constructing this and the succeeding tables of means a difiBlculty arose as to how to deal with those hours which on some of the days exhibited an acid, and on others an alkaline urine, such for example as from ten to eleven and eleven to twelve. The plan adopted has been to take a separate mean for the acid days and a separate mean for the alkaline days. This will explain why at these hours the urine is made to appear both acid and alkaline. Any obscurity or inconvenience arising from this will be obviated by a study of the companion tables, which give in extenso the daily results for the acid- ity and alkalinity. TABLE II. exhibits the hourly Variation of Reaction for the days composing Table I. The Phis sign is prefixed when the urine tvas Acid, and the Minus sign when Alkaline.
