In observation of the bicentenary of Erasmus Darwin's death, Cambridge is publishing this collection of personal writings by his grandson Charles. This is the first unabridged publication of a book by Charles Darwin, and it contains a series of illuminating insights into his grandfather's life and work. With quotations from letters and candid comments by Charles Darwin about his books; and free of the conventions of scientific writing; this small volume of personal observations illuminates the life of a distinguished scientist as seen by his accomplished successor.
