It is clear that loss of sulphate occurs. It is equally clear that this loss of
sulphate is not accompanied by a parallel loss of sulphur. The data are an indica-
tion of what is taking place. More accurate figures, obtained under exceptionally
favourable conditions, are given in a later table.

                    EXPERIMENTS WITH MATURE HAY.

                (a) Excretion of volatile phenols and sulphates.

Simultaneous determinations of volatile phenols and sulphates were made
firstly on the basal ration and secondly on the ration supplemented with sodium
