Set up a correspondence whereby 0. is mapped on that element a of K which is represented by the same qnotient. By the above remarks and (1) this is it one-toone correspondence [Section 2, (5), (0'), (E), (Il')] between the totality of elements of K and K. By (2) and (3) it satisfies the conditions Section 2, (3) and (4).
