the degrees of the difference of the longitudes of Ujjain and the different places by four. However, the amount thus found may differ in many cases from that assumed by the Hindus. The latter might easily be ascertained
if someone would collect from different places in India, | old native almanacs or Paichange. But they must refer
to an epoch not yet influenced by modern geographical science. By these means it would be easy to draw a MAP of India as it appeared to the Hindu themselves.
