This is done by using an affine algebra instead of a canonical one and also by using cocycle representations. A regularisation scheme allows us to find a history Hamiltonian which exists as a proper self-adjoint operator. The role of a cocycle choice is also discussed.31 pages, LaTeX, no figuresGeneral Relativity and Quantum Cosmologytext
