These are presented so as to focus attention on the observational problem of refinement and suggest the necessity for an alternative theory of `fractafolds' against which the limiting theory of $C^\infty$-differential manifolds usually underlying (quantum) general relativity can be measured.15 pages, 3 figuresGeneral Relativity and Quantum Cosmologytext
