Irritability, as commonly under- stood, is seen in its highest condition in muscular tissue ; but “the irritable power and an analogon of voluntary motion first dawn on us in the vegetable world in the stamina and anthers at the period of * Coleridge, p. 56. + “All vegetables,” says Sharon Turner, “from that pettiness which escapes onr natural sight, to that magni- tude which we feel to be gigantic, have these properties in common with all animals —organization ; an interior power of progressive growth, a principle of life, with many pheno- mena that resemble irritability, excitability, and suscepti- bility, and a self-reproductive and multiplying faculty.”’— Sharon Turner's Sacred History.
