NUMERICAL.

As each movement may be compared with three other movements, and as there were five subjects and four variations in the conditions, there are sixty opportunities of comparing the time required to move the image in the direction in which the object was moved with the time taken to move it in the other directions.  In 45 instances the time was less, in 3 the same, and in 12 greater.
