By adding together the several sums of _increase_ which have occurred in both classes, and the increase in the number of criminal lunatics, three hundred and forty-two (342), who have been provided for, since 1864, in a special asylum at Broadmoor; and deducting the sums of _decrease_ which have occurred by removals and redistribution of patients among the several asylums and registered houses, we have, as a grand total of _increase_ during the ten years, fourteen thousand two hundred and thirty-eight (14,238). I have presented the above statistics somewhat in detail, in order that it may be more apparent among what classes of society this large increase has mainly occurred. It will accordingly be observed that, while it has been only seventeen (17) per cent. among the private patients, it has been about seventy (70) per cent. among the pauper class. It is apparent that the above statistics present only the total number of increase, without relation to the increase of the population. To enable us to appreciate their full significance, another statement, therefore, becomes necessary. The ratio of the insane to the sane, the total number of the population being estimated at the middle of the year, for the several years of the decade, was as follows: In 1859 one in 535 " 1860 " " 523 " 1861 " " 507 " 1862 " " 495 " 1863 " " 478 " 1864 " " 466 " 1865 " " 460 " 1866 " " 449 " 1867 " " 441 " 1868 " " 430 exhibiting a higher ratio of the insane to the sane for every year of the decade. I now introduce the statistics of the second decade, viz., from 1869 to 1878 inclusive; and perhaps it is fair to assume that these will be more nearly perfect than those of the former period, as the system employed had been longer in operation, and the conditions of the problem somewhat simplified, as the result of previous labors. For convenience, I shall group together the private and pauper patients. In 1869, there were of both private and pauper patients in the county and borough asylums twenty-six thousand eight hundred and sixty-seven (26,867); in 1878, there were of the same classes of persons, thirty-seven thousand seven hundred and sixty-three (37,763): exhibiting an _increase_ of ten thousand eight hundred and ninety-six (10,896). There were in registered hospitals, in 1869, of both private and pauper patients, twenty-three hundred and fifty-two (2,352); and in 1878, twenty-seven hundred and seventy-eight (2,778): showing an _increase_ of four hundred and twenty-six (426). In licensed houses, there were, in 1869, four thousand seven hundred and ninety-six (4,796); and in 1878, there were four thousand two hundred and two (4,202): exhibiting a _decrease_ of five hundred and ninety-four (594). In naval and military hospitals, in 1869, there were two hundred and nine (209); and in 1878, three hundred and sixty (360): an _increase_ of one hundred and fifty-one (151).
