STATISTICAL. The patients on the register at the end of the year numbered 6,661 (m. 3,753, f. 2,908), or 278 (m. 181, f. 97) more than at the beginning; and the daily average under treatment during the year was 6,199 (m. 3,503, f. 2,696), or 267 (m. 161, f. 106) more than in the previous year ; while the total under care was 7,446. Patients belonging to the Native race numbered 98 (m. 51, f. 47) at the end of the year. The admissions numbered 1,063 (m. 587, f. 476), or 32 less than in the previous year. Of these, 157 had been previously under care, making the proportion of readmissions 14-77 per cent., and 906 patients were admitted for the first time. The ratio to population of all admissions (exclusive of Maoris) was 7-18 (m. 7-77, f. 6-56) to 10,000, and of first admissions 6-11 (m. 6-73, f. 5-46), so that 1,392 persons in the general population contributed one patient, and 1,636 contributed a patient admitted for the first time. The discharges (excluding transfers) numbered 365, or 17 less than in 1930. 118 (or 2 more) harmless unrecovered persons were returned to the care of friends; and 247 (m. 127, f. 120) recovered—l 9 less than last year —representing a percentage of 23-37 (m. 21-64, f. 25-21) on the total admitted. With voluntary boarders added the percentage rises to 36-13. Altogether, 44-52 per cent, of the inmates admitted were able to leave institutional care. Of a total of 7,446 patients under care, 420 (m. 221, f. 199) died, or 6-76 per cent, on the average number resident. An inquest is held in the case of every death, whatever the cause. The causes are detailed in Table XII, and the following is the percentage of causes mainly contributing : Senile decay, 28-12; disease of the brain and nervous system group, 31-25 ; heart-disease, 28-75 ; tuberculosis, 7-18. In Table XIII the principal causes assigned for the mental breakdown in the admissions are stated ; but as a matter of fact they are merely approximations, and these, with the small numbers with which we have to deal, show such divergences from year to year that the proportion assigned to any one cause in any one year cannot be assumed to be our average incidence. Causation is always complex, and the most potent factor is the individual. Hereunder the assigned causations in the table referred to are grouped and shown in their relative proportions :— Males.
