Abstract

1. 1. The concentrations of the major inorganic ions in the hemolymph of Periplaneta americana were determined as follows (in mM): Na+, 132; K+, 8.7; Mg2+, 4.7; Ca2+, 3.7; Cl-, 107; PO3-4, 1.04. 2. 2. By the method of ultrafiltration, significant binding to macromolecules in hemolymph was demonstrated for the following ions: Na+, 22.0%; Mg2+, 25.5%; Ca2+, 16.2%; C1-, 10.3%; PO3-4, 26.9%. 3. 3. K+ was not bound significantly to macromolecules in hemolymph.
