Darwin's study of barnacles, begun in 1844, took him eight years to complete. The correspondence reveals how his interest in a species found during the Beagle voyage developed into an investigation of the comparative anatomy of other cirripedes and finally a comprehensive taxonomical study of the entire group. Despite struggling with a recurrent illness, he continued to write on geologicy, and published notes on the use of microscopes. Three more children, Elizabeth, Francis, and Leonard, were born during this period, but the death of Darwin's father in 1848 left the family well-provided for.

Darwin spent a considerable part of 1879 in the eighteenth century. His journey back in time started when he decided to publish a biographical account of his grandfather Erasmus Darwin to accompany a translation of an essay on Erasmus’s evolutionary ideas by the German science writer Ernst Krause. Darwin’s preoccupation with his own roots ran alongside a botanical interest in roots, as he and his son Francis carried out their latest experiments on plant movement for the book they intended to publish on the subject. They concentrated on radicles—the embryonic roots of seedlings—and determined that the impetus for movement derived from the sensitivity of the tips. Despite this breakthrough, when Darwin first mentioned the book to his publishers, he warned that it was ‘dry as dust’.

In May 1865 a dispute arose between John Lubbock and Charles Lyell when Lubbock, in his book Prehistoric times, accused Lyell of plagiarism. The dispute caused great dismay among many of their mutual scientific friends, some of whom took immediate action to mediate a solution. Charles Darwin had close ties with both men and both sought his advice, but Darwin’s correspondence during this period reveals his reluctance to become directly involved in the dispute. Read more
