Würzburg is not an industrial town. There appears to be no special reason why the population and the wealth of the city should increase rapidly, and yet the old town is surrounded with fine new quarters, fashionable squares, pretty walks and fine wide streets, handsome houses and villas. Here, as elsewhere, that singular phenomenon of our age, the immense increase in the number of well-to-do families, is distinctly apparent. If this continue in the same proportions, the “masses” of the future will not be composed of those who live on wages and salaries, but of those living on profit, interest, or revenue. Revolutions will become impossible, for the established order of things would have more protectors than assailants. These countless comfortable residences, these edifices of all kinds which spring up in every direction, with their luxurious and opulent appointments, all this wealth and well-being, is the result of the employment of machinery. Machinery increases production and economizes labor, and as the wages of labor have not diminished, the number of those who could live without working has increased. Würzburg possesses an ancient University. It is a very old sixteenth-century building, situated in the centre of the town. As they recently did me the honor to confer on me the degree of _Doctor honoris causa_, I wished to see the Rector to offer him my thanks, but I had not the good fortune to meet him. On the Boulevard, special institutes have been constructed for each separate science, for chemistry, physics, and physiology. Immense sums have been spent in Germany to add a number of those separate institutes to the different Universities. The eminent professor of chemistry at Bonn, M. Kekulé, recently took me over the building constructed for his branch of science. With its Greek columns, and its palatial façade, it is considerably more extensive than the whole of the old University. The subsoil devoted to experimental and metallurgical chemistry resembles immense works or foundries. The professor’s apartments are far more sumptuous than those of the first authorities. Neither the Governor, the Bishop, nor even the General himself, can boast of anything to be compared with them. In the drawing-rooms and dancing saloons the whole town might be assembled. This Institute has cost more than a million francs. In Germany it is very rightly considered that a professor who has experiments to make ought to live in the same building where are the laboratories and lecture-rooms. It is only thus that he is able to follow analyses which need his supervision, at times even at night. Comparative anatomy and physiology have also each their palace. Several professors of natural sciences complain that it is really an excess. They say they are crushed by the extent and complications of their appurtenances, and especially by the cares and responsibilities they involve; nevertheless, if exaggeration there be, it is on the right side.
