Explanation:

 Kacharis were first classified by S. Endle. Mr. Endle's interest in his Kachari flock was that of an evangelist rather than that of a linguist or ethnologist, and this preoccupation has coloured his style and affected the matter of his book in a way that, however pleasant and natural it may seem to those who had the privilege of his acquaintance, may perhaps require a few words of explanation for the benefit of those who look for anthropology only, or linguistics, in his pages.
