They discovered, further, that these words and their roots meant always the same things, and this led to the natural belief that they came from the same source. Then, by closer inquiry into the Vedas, or Hindu sacred books, another discovery was made, namely, that while the Sanskrit has preserved the words of the original language in their most primitive or earliest state, the other languages derived from the same source have kept some forms plainly coming from the same roots, but which Sanskrit has lost.
