The sinistral is here the hand of nonattention; let us call it The Trailing Hand. Although for writing it is the life- long habitually disused hand, it was the one first used and habited in writing, and its central mechanism in the right cerebral half-brain has preserved perfection of function, despite disuse, and “trails” more perfectly than the dextral in the next example, 2bR. The lateral space is again less completely filled by the sinistral hand, although it is the “trailer.” Z 2^7?. No. 2bh and No. 2bR were written under the same con- ditions as No. 20L and No. 2aR, i. e. synchronously with- out visual attention, but with visual and central attention fixed upon the sinistral movements, the dextral hand being the trailer. The sinistral space again is not filled; the ac-
