Subtracting from the total amount of permanganate thus used the quantity required to equalize the 100 c.c. of solution No. 1 and the 100 c.c. of the manganous sulphate, we shall have the quantity of permanganate reduced by the nitric oxide.

It consists in precipitating all the manganese in the state of peroxide, dissolving it in a ferrous solution so as to bring back the manganese to the manganous slate, and determining volumetrically, by means of potassium permanganate, the quantity of ferrous salt which has been converted into ferric.

We also made a number of determinations, using a solution of manganous sulphate in the place of the oxalic acid.

One molecule of permanganate equals one molecule of nitric oxide when manganous sulphate is used, since no part of the permanganate employed in this method is reduced below the superoxide condition.

Finally, the excess of manganous sulphate is determined, in the manner described by Volhard, by means of solution No. 3.

The details of the method are as follows: A solution of manganous sulphate slightly stronger than No. 1 is prepared.

The advantage of this method lies in the fact that it is not necessary to dissolve the oxide which is precipitated upon the glass within the tubes, E, E, since, in the presence of an excess of permanganate, the reduction by nitric oxide extends only to the formation of MnO_ {2}; also in the fact that the solution of manganous sulphate is more stable than that of oxalic acid.

The contents of E, E, together with the rinsings from the tubes, are poured into a capacious flask. 100 c.c. of the manganous sulphate and
