By paper-chromatography 8 amino acids and 2 amides were detected in free state in root nodules. These were ordinary amino acids and amides found in plant tissues. There was no specificity of the nodules as compared with the roots and the leves. But their contents were higher in the nodules than in other parts of the plants. Considerable ammount of ammonia was found in the nodules. The ratio of glutamine to asparagine was larger in the nodules and smaller in the roots and the leaves. These facts suggest that the metablism of soluble nitrogen in the nodules is the similar assimilation process as the host plant tissue, and the nitrogen compounds transfering to the host from the nodules may be chiefly amino acids and amides; probably glutamic and aspartic acids their amides and alanine.
