DECREASE OF LUNACY IN LONDON.

According to the Parliamentary Returns in May, 1819, the total number of lunatics comprised in the circle of London and different private asylums, amounted to 2,005, which Dr. Burrows calculates as proving an increase of only five on an average in twenty years, notwithstanding the increase of our population. The late Dr. Heberden and Dr. Willan both concurred in this statement. The large district of Mary-la-bonne, which some years ago comprehended the greatest proportion of inhabitants in the metropolis, not less than 80,000,—from 1814 to the year 1819 received only 180 female lunatics, and 118 males.
