 between the nucleic acids" (by Rich. Cambridge, Mass.), "the adaptive 

 control of enzyme activity in animals" (by Knox, Boston, Mass.), "aspects of 

 chondrogenesis and myogenesis" (by Holtzer, Philadelphia, Pa.), "relation of 

 primary cell wall formation to cell development in plants" (by Jensen, Berke-
