The zoological boundary passing through the Bali Strait is called " Wallace's line," after the eminent naturalist who was its discoverer.
In 1882, for administrative purposes, Bali was separated from Java and combined with the island of Lombok to form the Dutch residency of Lombok and Bali.
The natives of Bali, though of the same stock as the Javanese, and resembling them in general appearance, exceed them in stature and muscular power, as well as in activity and enterprise.
Hinduism, which was once the religion of Java, but has been extinct there for four centuries, is still in vogue in the islands of Bali and Lombok, where the cruel custom of widow-burning (suttee) is still practised, and the Hindu system of the four castes, with a fifth or Pariah caste (called Chandala), adhered to.
