Two kinds of nonaggressive mice were used as subjects: 1) males from a strain selectively bred for nonaggressiveness (TNA) and 2) males from a strain selectively bred for aggressiveness (TA) but made nonaggressive by defeats in fights. The aggressiveness of neither type of animal was increased by injections of ethyl alcohol in concentrations of 1 gm/kg and 1.5 gm/kg. Three series of experiments were performed. The results were incompatible with the assumption of a general physiological aggression‐heightening effect of ethanol, and also with an assumption of removal by alcohol of learned inhibitions against aggression.
