On reisolation, successive scores tended downward toward the original level. On the other hand, the behavior of 16 male guinea pigs reared in groups 18 WILLIAM C. YOUNG and given 10 preliminary tests deviated markedly in a competitive situation according to the dominance or submissiveness of the animal. When they were replaced in isolation the behavior returned even more quickly to the level shown during the preliminary tests (Fig.

If stimulation is continued until voluntary termination is produced, the duration of the reflex can be measured with a stop-watch. T h e response may be considered terminated when any one of the following signs is evident: a) a sudden or gradual return of the back and pudendum to a normal position; b) a sudden return of the feet to the normal position and a loss of the wide stance cha1,acteristic of the reHex; c) kicking with the hind feet; d ) dashing forward; e) squatting; f) urinating; and g) an abrupt termination of the growl accompanied by a soft squeal.

Much of the description of the behavior as we have seen it and of the method we employed is repeated in this review, with the addition of quantitative features and relationships to changes in genital structures. The collection of many of the data depended on our willingness to make continuous, day and night observations over several consecutive reproductive cycles.
