coil from the primary remaiuved the same in the two observations (figs. 14 and 1B). 
The observation of fig. 1B was made from the same preparation as fig. 1a and about 
4 minutes later. The moment of delivery of the individual stimuli is marked by the 
abscissze on the myogram : in fig. 14 six were delivered before the reflex contraction 
set in ; similarly in fig. 1B, six were delivered before the reflex relaxation set in. The 
intensity of the stimulating shocks was feeble, hence the relatively long latent 
period. Time recorded in hundredth seconds above, in seconds below.
