In this obvious and easy manner he studied contemporary civilization in the capital.

He even carried his researches farther, and went one rainy afternoon to an exhibition of modern pictures in a pavilion of the Thiergarten, where from the small attendance he inferred an indifference to the arts which he would not ascribe to the weather.
