A different binding medium was identified in MS 965 (Rockefel-ler-McCormick New Testament), however. Figure 5 shows the spectrum obtained from a sample of the manuscript s sizing material. Although the spectrum is clearly not that of egg yolk, it has the features of a predominantly protein component. The protein-containing binders used in that period are presumed to include casein, egg white, and hide glue (25). The spectrum closely matches that of hide glue (26).
