Precession photographs of a native lysozyme crystal and a `renatured' cross-linked lysozyme crystal. The left-hand photograph is a 9° precession photograph of native lysozyme. The right-hand photograph is after the crystal was `swelled' by denaturation and renatured in the original supernatant (reproduced from Haas, 1968a
