Note 27 — Chapter I · EXPOSITION OF THE PROBLEM AND METHOD

The ethnographic sources do not differ essentially from the historical ones. The purpose of a descriptive ethnography (such as is adopted in this monograph) is also nearly identical with the historian's task so far as positive statement of an actual state of things is the aim of both. The rules of criticism of sources apply therefore to our subject as well as to any other historic science. This will become obvious to every ethnographer who reads the excellent manual of MM. Langlois et Seignobos. The proof of the indispensability of such a criticism is to be found there, too. The method of criticism of sources adopted in this paper was accepted after a careful study of this useful book.
