Abstract

1. After snails (Helix pomatia) have been infused with Na4EGTA, levels of unchelated Ca return to normal in about 0.5 hr and then rise higher. 2. In such snails HCO3 is probably added to the haemolymph in 2:1 ratio with the Ca, but depleted simultaneously by some other process. 3. The infusion of an extract of the ventral ganglia causes haemolymph Ca to rise. 4. Haemolymph Ca is not significantly affected by ecdysterone, cAMP, dibutyryl-cAMP or ionophore A23187.
