Even Sherrington's experiments do not relate to the present study directly as they were concerned with the immediate scratch reflex of the dog to a cutaneous stimulus, whereas this work² deals with a sustained type of itch paroxysm which tends to fluctuate in intensity between peaks separated by periods of exhaustion.
