“…after the labile isomer was precipitated by carbon dioxide. Identity was established by mixed melting point and by X-ray diffraction pattern: [10] 9.93; [8] 7.82; [5] 5.68; [3] 6.91, 5.90 (? ), 4.07; [2] 11.18, 4.25, 3.69; [1] 12.99, 4.41, 3.85, 3.62; [0.5] 6.51, 5.27, 4.98, 4.72, 3.49, 3.40, 2.98, 2.79, 2.69, 2.59, 2.45.…”

“…The X-ray diffraction pattern was: [10] 11.04, 6.80; [8] 4.57; [7] 5.90, 3.07; [6] 3.23; [5] In another experiment, which we cannot yet repeat and which involved a slow deposition out of ethanolic solution, we obtained a product of m.p. 134.5-135.5°of correct elemental composition which gave a different diffraction pattern, in part [10] 9.11; [7] 4.24; [6] 5.14, 3.81; [4] 7.39; [3] 6.21, after crystallization from benzene.…”
