 The captain had to record his survey in painstaking paperwork, and Darwin too kept a daily log as well as detailed notebooks of his finds and speculations, and a diary which became his journal.Darwin's notebooks show a complete professionalism that he had probably learnt at the University of Edinburgh when making natural history notes while exploring the shores of the Firth of Forth with his brother Erasmus in 1826 and studying marine invertebrates with Robert Edmund Grant for a few months in 1827.Darwin had also collected beetles at Cambridge, but he was a novice in all other areas of natural history.
