Tragacanth

Where what I have to note is too much to be included within the narrow limits of a margin, I commit it to a slip of paper, and deposit it between the leaves; taking care to secure it by an imperceptible portion of gum tragacanth paste.

There would have been many gums and resins in these markets for our lute-maker to bind his wood with: […] gum tragacanth from Aleppo, which would be sold as thin and wrinkled worm-like pieces of shrub.
