In the U. S. the census of 1880 reported 40,942 insane in hospitals, and 51,017 not in hospitals, a total of 91,959 known insane. In 1903 the number in hospitals had increased to 150,151. The number not in hospitals was not known and cannot be determined accurately, but it is conservatively estimated as certainly not less than 30,000, and probably it is far greater than this. But taking a total of 180,000 known insane as a conservative figure, the ratio of known insane in the total population was 225 per 100,000 in 1903, as compared with 183 per 100,000 in 1880. P. 33. The latest census reports for the U. S. give data relative to the dependents and defective in institutions. Insane and feeble-minded, at least 100,000; paupers in institutions 80,000, ⅔ of whom have children and are also physically and mentally deficient: prisoners 100,000; juvenile delinquents 23,000 in institutions; the number cared for in hospitals, dispensaries, homes of various kinds in the year 1904 was in excess of 2,000,000. From these figures we get a rough total of nearly 3,000,000. The foregoing are representative data:—they are published by the volume. It is always the same story—rapid increase of the unfit, defective, insane, criminal, slow increase, even decrease, of the normal and gifted stocks. It is with such conditions in mind that Whetham writes: “This suppression of the best blood of the country is a new disease in modern Europe; it is an old story in the history of nations, and has been the prelude to the ruin of states and the decline and fall of empires.” P. 35. _EUGENICS RECORD BULLETIN.

Cold Spring Harbor, N. Y._ In the report of the year ending September 30th, 1909, the New York State Commission in Lunacy gives the number of insane patients in state hospitals and private institutions as 31,540, or one to 276 in the general population. This figure does not include the inmates of institutions for the feeble-minded and for epileptics, it does not include the neuropathic subjects who find their way into prisons, reformatories, almshouses, dispensaries, hospitals for incurables, general hospitals, neurological clinics, etc., and above all, it does not include the many neuropathic subjects whose infirmities are latent, or of such nature as not to incapacitate them for ordinary occupations and life at large.
