My duty, in acknowledging the great obligations under which I lie to many naturalists, affords me most sincere pleasure. I had originally intended to have described only a single abnormal Cirripede, from the shores of South America, and was led, for the sake of comparison, to examine the internal parts of as many genera as I could procure. Under these circumstances, Mr. J. E. Gray, in the most disinterested manner, suggested to me making a Monograph on the entire class, although he himself had already collected materials for this same object. Furthermore, Mr. Gray most kindly gave me his strong support, when I applied to the Trustees of the British Museum for the use of the public collection; and I here most respectfully beg to offer my grateful acknowledgments to the Trustees, for their most liberal and unfettered permission of examining, and when necessary, disarticulating the specimens in the magnificent collection of Cirripedes, commenced by Dr. Leach, and steadily added to, during many years, by Mr. Gray. Considering the difficulty in determining the species in this class, had it not been for this most liberal permission by the Trustees, the public collection would have been of[Pg vi] no use to me, or to any other naturalist, in systematically classifying the Cirripedes...

A fresh account of Charles Darwin’s rich personal and professional lives, well beyond On the Origin of Species. In 1859 Charles Darwin published On the Origin of Species. With this bedrock of biology books, Darwin carved a new origin-story for all life: evolution rather than creation. But this single book is not the whole story. In this new biography, J. David Archibald describes and analyzes Darwin’s prodigious body of work and complex relationships with colleagues, as well as his equally productive home life—he lived with his wife and seven surviving children in the bustling environs of Down House, south of London. There, among his family and friends, Darwin continued to experiment and write many more books on orchids, sex, emotions, and earthworms until his death in 1882, when he was honored with burial at Westminster Abbey. This is a fresh, up-to-date account of the life and work of a most remarkable man.
