DARWIN, Charles & FrancisBiblio.com

The Power of Movement in Plants.

1880156556London: John Murray 1880. It has always pleased me to exalt plants in the scale of organised beings First edition first issue of Darwin's penultimate book continuing his experiments with climbing plants and prepared with the assistance of his son Francis. The first issue is distinguished by the presence of two lines of errata on p. x which are corrected in the second issue of the same year. The collaborative authorship proclaimed on the title page reflects Darwin's interest in introducing his children into the world of science. Francis Darwin had trained as a doctor but turned from medicine to botany initially working as secretary and assistant to his father. In 1876 he had been for some months at the University of Würzburg learning laboratory methods from Julius Sachs. "The book was an extension of Charles Darwin's work on climbing plants and it showed that the same mechanisms can be observed in plants in general. By extending the idea of irregular circumnutation the Darwins analysed the growth movement of plants in response to factors of the environment such as light gravity and wounds. In addition they demonstrated that the mechanism of curvature in both roots and shoots was the result of differential growth rates. They could also confirm that the effect of the stimuli on the growth movement was indirect and that light and gravity act on some substance in the tip of the root and the shoot which is transmitted to other parts of the plant. Francis Darwin later refined some of the experimental techniques and modified their theoretical conclusions" ODNB. Provenance: with the ownership signature of Ralph W. Lewis dated 1949 on the half-title. Lewis was a professor of botany plant pathology biology and natural science at Michigan State University from 1937 to 1980.
