Abstract

1. Sodium in the blood of Helix aspera varied between 58 and 138 mM/l. and other cations comparably. 2. In specimens that had fasted 1–11 days and had then been in contact with water for 2 hr, sodium, potassium, calcium and magnesium averaged 68 ± S.D. 6, 2·9 ± S.D. 0·3, 6·2 ± S.D. 1·1 and 3·6 ± S.D. 1· 2 M/l respectively. 3. Potassium levels of about 3·5 mM/l. occurred in hydrated specimens previously long inactive. 4. Potassium and calcium tended to rise after a meal. 5. There were marked correlations between potassium and calcium and between sodium and magnesium. 6. When levels of potassium in the blood were artificially raised, those of calcium also rose. The converse effect was small or absent.
