On page 41, it is written “ ..In this case, his( james) unvarying frankness and candour have of themselves paved the way for my justification, and I doubt not that, had his intellect been spared to us,he would himself have been prompt to reduce to more consistent and mature theory, the imperfect hypothesis somewhat hastily enunciated on the initiatory publication of these fac-similes.”. It clearly says, it is imperfect hypothesis somewhat hastily produced. In same book, On page 42, it is written - “As respects the derivation of the literal series, Princep had clearly a leaning towards associating with the Greek, grounded upon the similarity,and almost identity of some of the forms of each,the phonetic value of which fell into appropriate accord.That these similitude's exist there can be no doubt,but not in sufficient numbers or degree to authorize an inference that one system borrowed directly from other. So from above quotes, it is clear that James Princep's tables are nothing but Imperfect Hypothesis. Book which published those tables in 1858,says so.
