Criticizing the former theories on metamorphism that had been set up by the past authors such as Grubenmann-Niggli, Harker etc., the writer emphasized that the role of "metasomatism" in rook-alteration must be all the more greatly weighed in our future studies. In order to get the recognition of the true nature of metasomatism, we must proceed our investigations not with the descriptive or abstract phisico-chemical methods, but with the historical and geological methods firmly .based on our energetic field-works. So we should always understand the metamorphic rocks as the "Produkte der tektonischen Vorgange" as Eskola says. In the sense of the above, it is by all means needed to consider the present problem…… the cordierite-metasomatism or Mg-Al metasomatism…… from a higher standpoint without restricting our scope of object merely to this special rockfacies.
