Experiments showed, that it is not possible to extract the organic matter of the oil shale without decomposing the substance. The present paper reports the quantity of nitrogen in several organic matters. The quantity of nitrogen remains nearly unchanged at the used operations. A considerable higher quantity of nitrogen was found only in one fraction. The consequences from this were discussed.
