The General’s well At one time, Inverness had several healing walls, each of the wells was visited for a different cure – the General’s Well being the one to visit for a cure for rickets. After silvering the water the custom was to bathe the afflicted limbs and also to drink the water. Being so conveniently near the town it was much frequented and the number and variety of diseases it could subdue were proportionately great. Far and near, children and young persons afflicted with rickets were brought to it and manipulated upon by its waters . To strengthen the virtue of the water, silver coins of all sizes, together with small pebbles, were immersed in the well and various curious ceremonies were observed.
