In an attempt to view the onset of urea denaturation in ribonuclease we have collected X-ray diffraction data on ribonuclease S crystals soaked in 0, 1.5, 2, 3, and 5 molar urea. At concentrations above 2 M urea, crystals were stabilized by glutaraldehyde crosslinking. We have also collected data on
