Abstract

1. Snails were relaxed completely with 25–33 μmol Mg/g body wt, but some recovered fully within 15 min while haemolymph Mg was still about 10 times the normal value. 2. After injection of MgCl2, haemolymph Mg fell over 1–2 days, but remained above normal. 3. The crop accumulated a Mg-rich fluid, approximately isosmotic with haemolymph. 4. The hepatopancreas lost water and the ratios of Mg to Ca and to phosphate within it increased. 5. Raised haemolymph Mg could prevent the neuromuscular response to infused KCl, but not the subsequent elevation of haemolymph Ca.
