The fatigued muscles recover as soon as the stimulation ceases,and the more rapidly, the less was the degree of fatigue. Inrecovery the irritability gradually increases; the various pheno-mena of fatigue, which can be seen in the curve of contraction,gradually pass away, and, finally, the muscles are in the samecondition as before. H H 466 GENERAL PHYSIOLOGY That which appears especially interesting is the fact, discovered byValentin (47), and Eduard Weber (46), that excised muscles alsoare capable of recovery. This, also, can best be seen by the aid ofthe graphic record of the muscular move
