I recently read this book about a guy who, along with his sister, might have killed their younger brother in England in 1860. It wasn't that interesting.

However, what was interesting is that the guy grew up to become a marine biologist and moved to Australia and became one of the most influential researchers to study the Great Barrier Reef. (Isn't it funny that, a week since I finished reading that book, what stays with me is not the subject, but what one of the participants did years after?)

Well, anyway, the picture is of the cover and title page of his influential book and a detail from one of the color plates he created showing life on the reef.

You can read more about the man, William Saville-Kent, here.
