The Power of Movement in Plants is the title of another work by Charles Darwin, assisted by Francis Darwin. It is even more interesting and curious than the previous one noticed in this column on their twining. It proves motion in the roots and leaves. In the former this gives the tip the power of avoiding difficulties of hard ground, or rather of selecting the softest course, and of going to the moistest as well as occupying any worn route. We can only indicate the importance of the book. It will be sought by those who love the study of nature, and will be found to be the most important of Darwin's botanical works.
