SOSTOMAGUS in Gallia, is placed by the Jerusalem Itin. between Tolosa ( Toulouse) and Carcaso ( Carcassone), 38 miles from Toulouseand 24 from Carcassone. The road is nearly direct, and if the distances are correct, we might, perhaps find some name like Sosto in the proper place. Some geographers have found Sostomagus near Castelnaudari
