This formulation gives pele mele a detailed summary of the set of results that should appear in a final formulation. To arrive at the latter we need to reorganize thoroughly the present stage zero. The first, step should probably be to make a new plan (in which without, a doubt the present sections 11, 12, 14, 15 will conic much earlier). I have not even written section 16 which should neither in principle cause any difficulty nor does it influence in any way the previous Nos. since what is involved is a simple matter of translation.
