I spent the afternoon sketching at the Grant Museum of Zoology, part of University College London. It’s an amazing collection of zoological specimens and other oddities, such as the mid-18th century Blaschka glass specimens – beautifully detailed life size models of snails, slugs, jellyfish and squid. Other favourite items included a disembodied chimpanzee hand, a jar of moles (rather like a jar of sweets but more macabre, with little pink paws instead of wrappers), and a large model of an elephant’s heart.
