"(d) Acute hallucinosis: This is chiefly an auditory hallucinosis of rapid development with clearness of the sensorium, marked fears, and a more or less systematized persecutory trend. "(e) Chronic hallucinosis: This is an infrequent type which may be regarded as the persistence of the symptoms of the acute hallucinosis without change in the character of the symptoms except perhaps a gradual lessening of the emotional reaction accompanying the hallucinations. "(f) Acute paranoid type: Suspicions, misinterpretations, and persecutory ideas, often a jealous trend, hallucinations usually subordinate; clearing up on withdrawal of alcohol. "(g) Chronic paranoid type: Persistence of symptoms of the acute paranoid type with fixed delusions of persecution or jealousy usually not influenced by withdrawal of alcohol; difficult to differentiate from non-alcoholic paranoid states or dementia praecox. "(h) Alcoholic deterioration: A slowly developing ethical, volitional and emotional change in the habitual drinker; apparently relatively few cases are committed, as the mental symptoms are not usually looked upon as sufficient to justify the diagnosis of a definite psychosis. The chief symptoms are ill humor and irascibility or a jovial, careless, flippant, facetious mood; abusiveness to family, unreliability and tendency to prevarication; in some cases definite suspicions and jealousy; there is a general lessening of efficiency and capacity for physical and mental work; memory not seriously impaired. To be excluded are residual defects due to Korsakow's psychosis, or mental deterioration due to arteriosclerosis or to traumatic lesions. "(i) Other types, acute or chronic (to be specified)." Shadwell[222] states that in twenty-six Italian asylums 18.6 per cent of their cases were directly or indirectly the result of alcoholism. Twenty-one and one-tenth per cent of the males and 4.37 per cent of the females admitted to the institutions of Switzerland from 1901 to 1904 were alcoholics. Twenty-one and thirty-seven hundredths per cent of the admissions to the hospitals in Denmark between 1899 and 1903 were suffering from alcoholic psychoses. He gives the admission rate in Austria as fourteen per cent and in France, 12.5 per cent. Clouston some years ago estimated the admission rate in Great Britain and Ireland to be about twenty per cent.
