`The agreement is good enough to warrant comparison of all the data
`with that of pattern 4-726 (Fig. 7—]B). When this is done agreement is
`satisfactory (within experimental error) for all lines. and no lines of the
`unknown pattern are unz1t::1ounted for. This confirms the identity of the
`unknown as KF.
