In the “Journal of Mental Science” for April, 1883, I presented some statistics as to the recovery and death-rates of asylums, especially directed to the question of the effect of the size of the asylum upon them. In that communication I stated an opinion (p. 9) that the dominant element governing the different rates of recovery in different asylums was to be found in the different classes of cases admitted into different asylums, and expressed a hope of some day being able to make a further research in this direction. Table VII. of the tables of the Association obviously afforded the most hopeful available means of doing so, but how much could not be seen until a laborious abstract of its contents for a number of asylums over a series of years was made.
