Atkinson, Himalayan Gazetteer, Vol. 2, Part 2 (1981), pp. 679–680: "Captain Webb and others showed that the lesser stream flowing from the sacred fountain of Kalapani had always been recognised as the main branch of the Kali and had in fact given its name to the river during its course through the hills. The Government, therefore, decided to retain both Nabhi and Kunti, which have ever since remained attached to British Byans."
