It will be well known to all to whom these remarks are addressed, that Statistical Tables of the Causes of Insanity in the Admissions into Asylums began to be collected by the English Commissioners in Lunacy for the first time in 1876. In that year returns upon a definite system and plan were asked for and received from all asylums throughout England and Wales, the results being published in the Commissioners' Blue Book for that year. In the following year, 1877, the corresponding statistics were not collected, but in 1878 they were resumed in a slightly modified form as regards the list of causative agencies from that originally issued, and, on the amended plan, they have since year by year been continued.
