572 Prof. C. 8. Sherrington. On Reciprocal [Nov. 3, 
speed, and in about 6 seconds after cessation of the stimulus the muscle 
had nearly regained the length it had just prior to the observation. — 
Fig. 3. 
The observation of which fig. 3 reproduces the record was carried out some- 
what similarly to that of fig. 2. The stimulation of the excitatory afferent 
nerve was of the same intensity as in fig. 2, but was continued longer. The 
stimulation of the inhibitory afferent nerve was, however, weaker, namely 
75 Kronecker units instead of 100; it was, however, three times as prolonged. 
Under the simultaneous stimulation of the two nerves the muscle assumed 
and maintained, as the record shows, a degree of contraction greater than 
under the combined stimulation in the experiment furnishing fig. 2.
