Reading edition
For the further pursuit of this subject the reader should consult Sachs' Lectures, II. and XV.; Sorauer, A Popular Treatise on the Physiology of Plants, 1895, chapters II. and IV., and Pfeffer's Physiology, pp. 149-163. The principal paper on root-hairs referred to in the text is Schwarz, "Die Wurzelhaare der Pflanzen," in Unters. aus dem bot. Inst. zu Würzburg, I. Heft 2, 1883, p. 140, where a very exhaustive account of these organs will be found.
