This walking stick belonged to Charles Darwin. It's made from whalebone and an ivory-carved skull pommel with emerald eyes. The cane is my favourite random memento of the thousands on display at the Wellcome Collection. Over two floors of well-lit cabinets you'll find eccentric tidbits from human history like: an 800-year-old mummified Peruvian, Aleister Crowley's stash container, a Chinese torture chair, a shrunken head from an Amazonian tribe. It's a bit like rummaging through Indiana Jones' basement.
* The Wellcome Collection is opposite Euston Station and it's free to get in.
