Please note that the following alterations should be made to the data given in “Some Ternary and Higher Order Platinum Group Metal Alloys”, which appeared in Platinum Metals Rev., 1987, 31, (2), 74–90.

On page 83, in Figure 12 the temperature given as 1200°C should be 1250°C; also Figures 12 and 13 should be transposed, but not the related captions. On page 85, within Figure 16, Pt-55Pd-55Rh should read Pt-55Pd-15Rh.

Any confusion caused is greatly regretted.
