Page "Comparative method" Paragraph 3

In the present work an attempt is made to set forth the inferred Indo-European original language side by side with its really existent derived languages.

Besides the advantages offered by such a plan, in setting immediately before the eyes of the student the final results of the investigation in a more concrete form, and thereby rendering easier his insight into the nature of particular Indo-European languages, there is, I think, another of no less importance gained by it, namely that it shows the baselessness of the assumption that the non-Indian Indo-European languages were derived from Old-Indian ( Sanskrit ).
