Excerpt from Tobacco and Its Adulterations There is not a plant that grows but has its leaves formed on a fixed and definite plan and in each plan may be distinctly traced a peculiarity of its own. The shape which leaves assume is, in some instances, of so marked a character as to enable us to predict with certainty the poisonous properties of the plant which has produced them; whilst the arrangement Of their veins is a no less certain index of the internal structure Of the stem on which they have grown, and even Of the seed from which their parent plant has been derived. Thus the oak-leaf and the acorn alike inform us of the arrangement of the minutest fibres within the giant stem which has supported and matured them.
