"A classic work on the science of plant breeding and the role of selection and hybridization in the improvement of agricultural crops. The author a renowned Dutch botanist and geneticist presents his own experiments and observations as well as a review of the work of his predecessors and contemporaries. This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it." Creative Media Partners Reprint Hugo Marie de Vries 1848-1935 was a Dutch botanist and one of the first geneticists.

"A perusal of the Lectures will show that the subject matter of "Die Mutationstheorie" this work was translated in full into English in 1909-10 has been presented in a somewhat condensed form and that the time which has elapsed since the original was prepared has given the oppurtunity for the acquisition of additional facts and a re-examination of some of the more importent conclusions with the result that a notable gain has been made in the treatment of some complicated problems." Editors Foreword. - "New experiments and observations have been added and a wider choice of the material offered by the more recent current literature has been made in the interest of a clear representation of the leading ideas."Author's Preface. </em> hardcover

IIVIII4831 pp. a. 10 lithographed plates some in colour. De Vries' paper: pp. 117-126. Internally clean and fine partly unopened. <br/><br/><em>First appearance of this importent paper on osmosis in which De Vries gave the name of 'PLASMOLYSIS" to a chemical concentration of the cytoplasm and linked it with the increased osmotic pressure outside the cell. he also introduces the concept "isotronic" denoting the ration of concentrations the 'isotronic coefficient'."In 1871 he was studying the changes induced in fragments of beetroot immersed in various solutions. The sugar and the cytoplasmic pigment never entered the bath. In contrast if the concentration of cane sugar or sodium chloride in the external liquid were raised the cytoplasm contracted returning to its normal volume when exposed to pure ayer. The impermeability of the cell wall to cane sugar and sodium chloride and the ready passage of water through it was thus established. De Vries gave the name of plasmolysis to this concentration." </em> unknown
