[17] Regeneration implies that there has been degeneration, and it cannot be positively affirmed that such degeneration has, on the whole, occurred in such a manner as to affect the race. Reibmayr (_Die Entwicklungsgeschichte des Talentes und Genies_, Bd. I, p. 400) regards degeneration as a process setting in with urbanization and the tendency to diminished population; if so, it is but another name for civilization, and can only be condemned by condemning civilization, whether or not physical deterioration occurs. The Inter-departmental Commission on Physical Deterioration held in 1904, in London, concluded that there are no sufficient statistical or other data to prove that the physique of the people in the present, as compared with the past, has undergone any change; and this conclusion was confirmed by the Director-General of the Army Medical Service. There is certainly good reason to believe that urban populations (and especially industrial workers in factories) are inferior in height and weight and general development to rural populations, and less fit for military or similar service. The stunted development of factory workers in the East End of London was noted nearly a century ago, and German military experience distinctly shows the inferiority of the town-dweller to the country-dweller. (See e.g. Weyl, _Handbuch der Hygiene_, Supplement, Bd. IV, pp. 746 _et seq._; _Politisch-Anthropologische Revue_, 1905, pp. 145 _et seq._) The proportion of German youths fit for military service slowly decreases every year; in 1909 it was 53.6 per cent, in 1910 only 53 per cent; of those born in the country and engaged in agricultural or forest work 58.2 were found fit; of those born in the country and engaged in other industries, 55.1 per cent; of those born in towns, but engaged in agricultural or forest work, 56.2 per cent; of those born in towns and engaged in other industries 47.9 per cent. It is fairly clear that this deterioration under urban and industrial conditions cannot properly be termed a racial degeneration. It is, moreover, greatly improved even by a few months' training, and there is an immense difference between the undeveloped, feeble, half-starved recruit from the slums and the robust, broad-shouldered veteran when he leaves the army. The term "aggeneration"--not beyond criticism, though it is free from the objection to "regeneration"--was proposed by Prof. Christian von Ehrenfels ("Die Aufsteigende Entwicklung des Menschen," _Politisch-Anthropologische Revue_, April, 1903, p. 50).
