10a.Topping up of a vessel to full capacity,for example to compensate for evaporation(6) ?L?ING
18d.Feudal lord having royal authority(9) P?L?G?E?E - thought Palgrave but doesnt fit?
Many thanks - think I may have 30a wrong. Having 10 feet,like crabs,lobsters & prawns(10) I put Pereiopods which conflicts with Palgrave, and couldnt make decapods fit!!
