The response of secondary endings of de‐efferented muscle spindles in the soleus muscle of the anaesthetized cat was recorded during stretching of the muscle at velocities of 5‐30 mm/sec. Stimulation of single fusimotor fibres, most and probably all of which were static fusimotor fibres, produced no appreciable change in the normally small dynamic sensitivity of these endings.
