II. When the receiving and expressing senses are different. 
(1) If the eye is the expressing sense, and (a) the hand the 
receiving sense, 
lengths are greatly underestimated, the error decreasing as 
the length increases, ‘ 
If the eye is the expressing sense, and (4) the arm the receiving 
sense 
All lengths are greatly naderestimated, the error decreasing as 
the length increases. By combining the two conclusions we see 
that,— 
If the eye is the expressing sense, all lengths are greatly un-

All lengths are greatly exaggerated, the error daaag as
