— RNA and DNA were determined in the axoplasm and sheath of squid giant axons. If the RNA was related to axonal length, equivalent amounts of RNA were found in the axoplasm and sheath. However, when it was expressed as a function of dry wt. or residue protein, the concentration of RNA in the sheath was four times greater than in the axoplasm. A ratio of 1·1 was found for sheath RNA/sheath DNA. Less DNA was present in the axoplasm than the amount which could be accurately determined with the methods employed.
