London's Natural History Museum opens
Originating from collections within the British Museum, the landmark Alfred Waterhouse building was built and opened by 1881. The museum is home to life and earth science specimens comprising some 70 million items within five main collections: Botany, Entomology, Mineralogy, Palaeontology and Zoology. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Darwin.
