More errors were made at these points when the left ear was 
closed than when both were open. The same number of errors in 
the aggregate was made with the two instruments, and nearly the 
same at the two points o and 50. Upon the whole there was a 
slight inclination to err towards the right. 
The following diagrams show the points at which each sound 
was located. The Roman numerals indicate the points where the 
sounds were produced. The figures at the end of the heavy lines

represent the number of sounds supposed by the subjects to be 
located at those points. (A) represents the supposed locations of 
the sounds when the subjects used both ears, and (b) when they 
used only the right ear. As there are two hundred and forty lines 
in each diagram and twelve points where sounds were made, twenty 
lines would terminate at each point, if all the sounds had been cor- 
rectly located by the subjects. The tendency in the diagrams to 
vary from this regular arrangement shows the general trend of 
errors in locating the sounds.
