Hobson-Jobson — I
(1903)
“ The compromise between the vaguer and the more precise use of the term is seen in Ptolemy, where the boundaries of the true India are defined, on the whole, with surprising exactness, as 'India within the Ganges,' whilst the darker regions beyond appear as 'India beyond the Ganges.' And this double conception of India, as 'India Proper' (as we may call it) , and India in the vaguer sense, has descended to our own time. ”
