Good bits of Culture on Victorian Science & Spiritualism

I've started a lot of these type of threads recently but you're all so good at giving me answers so I hope you'll forgive another one.

I'm writing a libretto for an opera about W.T Stead who was a late 19th Century journalist who had an obsession with contacting dead spirits. He believed he was in contact with a spirit called Julia (an American woman he had met once) for a number of years, contacting her through 'automatic writing'. He attempted to make a empirically valid method of contacting spirits through something he called 'Julia's Bureau', where three mediums would contact a particular spirit without having had any contact with each other prior to or after the event.

Obviously this was an idea very much in keeping with the spirit of the age (not deliberate naff pun), where people were excited by the new horizons afforded by scientific methods even though they were unable to imagine exactly how this would take shape.

I'm looking for any good bits of culture (documentaries/books/films etc.) that might give me an interest into the late 19th cenutry mindset, into Victorian attitudes to science and to spiritualism more generally.
I've already read quite a bit about Conan Doyle and watched The Prestige but that's about it.
