That a uniform statistical method should be generally adopted by all those connected with the insane is greatly to be desired, for though statistical researches have met the fate of all other methods (‘Annales Psychologiques,’ July, 1856), have been received with un-reflecting infatuation, or been the subject of unmerited reproach, according as they have given us useful facts or have led us into error, yet everything leads us to expect that the extension of a statistical programme, would furnish us with useful data, for the examination of some of the most important questions relative to mental alienation.
