Abstract
X-RAY photographs of zinc insulin crystals in several immersion media have been obtained by D. Crowfoot and D. Riley. The wet crystal unit cell is found to be a moderately expanded version of that previously found for the air-dried crystals. Preliminary calculations show that the striking differences in the X-ray intensities given by the different crystal structures is to be correlated mainly with a reorientation of the molecules relative to the crystal axes which takes place on drying.
