In "Compressive Mechanical Properties of Human Cancellous Bone after Gamma Irradiation" (74-A: 747-752, June 1992), by Anderson et al., Figure 3 on page 749 is incorrectly labeled Figure 2. In addition, Figures 3 and 4. on page 750, are transposed. The correct legend for Figure 3 is "A typical load-displacement curve. The zero position is arbitrary." The correct legend for Figure 4 is "Log failure stress versus log density for all control specimens."
