1. The effects of ethylendiaminetetraacetate (EDTA), inorganic tripoly-metaphosphate (TP), citrate and oxalate on the mechanical properties of glycerinated muscle fibers in relation to magnesium and calcium were studied.2. EDTA and TP could cause the fiber contracted by ATP to relax in the presence of Mg and ATP together.3. Relaxing effect of EDTA was abolished by the presence of Ca as well as by Mn in a stoichiometric relation with the concentration of these metals.4. Citrate and oxalate, while expected to have the same action of combining with these metals as EDTA, could not be substituted for it in producing mechanical change in glycerinated fibers.5. Relaxing effect of the so-called relaxing factors seems to depend on their action of forming a complex with Mg and at the same time with contractile protein too in cooperation with ATP.6. Effective concentration of magnesium bound to the contractile elements appears to be essential for contraction as well as for relaxation of them.The author's sincere thanks are due to professor G. Kato for his encourage-ment and to professor T. Hayashi for his kind revision and encouragement.
