_Wood of the Cross_ (Vol. vii., pp. 177. 334. 437. 488.).--Is it an old
belief that the cross was composed of four different kinds of wood? Boys,
in a note on Ephesians iii. 18. (_Works_, p. 495.), says, "Other have
discoursed of the foure woods, and dimensions in the materiall crosse of
Christ, more subtilly than soundly," and refers in the margin to Anselm
and Aquinas, but without giving the reference to the exact passages. Can
any of your readers supply this deficiency?
