Actin, actomyosin, its reactions with ATP, the glycerinated muscle fiber 

 — all discoveries of the author and his associates — were reported in the 

 first two editions of "The Chemistry of Muscular Contraction." These 

 studies have now been extended and a first attempt has been launched to 

 fit actomyosin into the cellular entity'.
