The book is one of those temper of the times books: a book trying to get into the mindset of period. Such books with bizarre titles such Darwin's Cockatoo have become an industry and a curse: especially as they've gotten monstrously big. But some are enlightening---and not just rehashes of better books. Somerville's book is a good and very early example. It's one of those books that stand repeated rereading. Somerville's modest and amusing and doesn't strain at new explosive revelations. He certainly misses a lot---not much on women or sex---but what he gives seems good. And he was close enough in time to the Victorians that he knew them from the inside.
