The results of this study indicate that the originally proposed space group and structure (Garrido, 1932; Minder, 1935; Amoros, 1945) are in- consistent with the results of nuclear magnetic resonance studies (Blood & Proctor, 1954; Waterman, 1954; Waterman & Volkoff, 1955; ])as, 1957). Synthetic crystals prepared by Dr W.T. Schaller, U.S. Geological Survey, were examined by the Weissen- berg method using Cu Ka and Me Ka radiation. The correct space group was found to be P21/c not P2/c, owing to the presence of a screw axis since there were systematic extinctions of 0/c0 for k ~= 2n. The Lmit-cell dimensions, obtained from zero-layer line photographs of rotations about the a and b axes yielded the following values: a = 7-022, b -= 9.151±0.002, c =
