Fig. la: Syringing of the left auditory meatus with cold water. It will be seen 
that immediately after the douching a nystagmus appears, in which a slow 
contraction is invariably followed by a quick relaxation. 
Fig. 15: Illustrates the same with a quicker rotation of the kymograph. (The 
lever is shifted more towards the timeline, so that the contraction of the M. externus 
is not so small as it looks to be). 
Fig. le: Syringing of the right meatus with cold water. 
Here just the reverse takes place to Fig. la. Slow relaxations are followed by 
rapid contractions. The intense relaxation is very apparent just at the beginning 
of the douching. 
Fig. 1d: Presents the same picture as Fig. lc at a later douching of the left 
meatus, with which the alternating relaxations and contractions are still distinctly 
visible.
