Editorial note — Comparative Mortality of Great Capitals.

[Footnote 140: M. Vacher here tells a story of his endeavor to make some ozonometrical observations in the Paris hospitals, which were prohibited by the Directeur de l'Assistance publique—an officer of whom M. Vacher is continually complaining on the ground that they would frighten the patients. He remarks that on one occasion when travelling in the pontifical states, some gendarmes found in his possession a psychrometer and an aneroid barometer, and thought they were weapons of destruction. He would have been arrested but for M. Matteucci, then Director of Police. He complains bitterly of the comparative want of enlightenment in the "administration" of his own country. But no hospital would have allowed his experiments.]
