Note 279 — MADDER.

I do not know that any one ever remarked human bones to have been dyed by madder, though the proposal for using the roots of it against the rachitis might have given occasion to make observations on that subject. See G. L. Hansen, Diss. de Rachitide. Gottingæ, 1762, p. 36. Professor Arnemann, who has a very numerous and valuable collection of skeletons, and who carefully examined many of the like kind during his travels, assured me that he never saw any bones that had been dyed by madder in the human body.
