Abstract
The practical values surveyed by means of electric prospectings have their seasonal variations according to the geology of the area.
In every four seasons they have peculiar p-a curves, especially in the pyroclastic areas. On the seasonal variations in the former paper by the author, someone were against him, though they should recognize the fact that the features of the p-a curves resulted from the practical survey coincide with the geology of the practical area. And then, their attitudes as if they close their eyes to facts on the ground that the seasonal variations of p-a curves do not coincide with their theoretical values, must be revised frankly.
