B's Reactions to Red-Green. 



B was given test for test with J (see J's record) with similar averages up to March 25th. Notice- 

 able position error began to appear which grew steadily worse. This error, as in H's case, was 

 finally eliminated by the introduction of the glass partition. The error persisted for fifty-one 

 days. Ten to twelve trials were given per day during this entire period.
