In various publications (Arb. Wtirzb. 2, pp. 291 sqq. ; Lectures, pp. 225 sqq.) 

 Sachs upheld the theory of Unger, according to which water travels in the lignitied 

 walls of the water- conducting elements, and not in their cavities. This " imbibition 

 theory " of the ascent of sap, which held the field for a considerable time, was first 

 successfully attacked by Bohm ; it is now merely of historic interest.

166. Strasburger (I.e. [157], p. 474; also Textbook of Botany [3rd Engl, ed.], 

 p. 113) does not recognise the existence of a " cambiform tissue," as distinguished 

 from ordinary leptome-parenchyma (phloem-parenchyma, cribral-parenchym). The 

 author dissents from this attitude. It is true that the recognition of the separate
