title: Cation concentrations in the hemolymph of Loligo pealei.
abstract: Hemolymph and protein-free hemolymph obtained from Loligo pealei were analyzed for cation concentration by the method of atomic absorption spectroscopy, for the following ions: Na+, K+, Ca++, and Mg++. No significant differences were seen in ion concentration between hemolymph and protein-free hemolymph. Of particular neurophysiological significance is that K+ ion concentration is much closer to that of seawater than previously reported.
