This point is so important that it may be well to quote Mr. Tylor's statement of the value of the anthropological criterion:-- It is a matter worthy of consideration that the accounts of similar phenomena of culture, recurring in different parts of the world, actually supply incidental proof of their own authenticity. Some years since a question which brings out this point was put to me by a great historian, "How can a statement as to customs, myths, beliefs, etc., of a savage tribe be treated as evidence where it depends on the testimony of some traveller or missionary who may be a superficial observer, more or less ignorant of the native language, a careless retailer of unsifted talk, a man prejudiced, or even wilfully deceitful?" This question is, indeed, one which every ethnographer ought to keep clearly and constantly before his mind. Of course he is bound to use his best judgment as to the trustworthiness of all authors he quotes, and if possible to obtain several accounts to certify each point in each locality. But it is over and above these measures of precaution that the test of recurrence comes in. If two independent visitors to different countries, say a mediaeval Mohammedan in Tartary and a modern Englishman in Dahomey, or a Jesuit missionary in Brazil and a Wesleyan in the Fiji Islands, agree in describing some analogous art, or rite, or myth among the people they have visited, it becomes difficult or impossible to set down such correspondence to accident or wilful fraud. A story by a bushranger in Australia may perhaps be objected to as a mistake or an invention; but did a Methodist minister in Guinea conspire with him to cheat the public by telling the same story there? The possibility of intentional or unintentional mystification is often barred by such a state of things as that a similar statement is made in two remote lands by two witnesses, of whom A lived a century before B, and B appears never to have heard of A. How distant are the countries, how wide apart the dates, how different the creeds and characters of the observers in the catalogue of facts of civilisation, needs no farther showing to any one who will even glance at the footnotes of the present work. And the more odd the statement, the less likely that several people in several places should have made it wrongly. This being so, it seems reasonable to judge that the statements are in the main truly given, and that their close and regular coincidence is due to the cropping up of similar facts in various districts of culture. Now the most important facts of ethnography are vouched for in this way. Experience leads the student after a while to expect and find that the phenomena of culture, as resulting from widely-acting similar causes, should recur again and again in the world. He even mistrusts isolated statements to which he knows of no parallel elsewhere, and waits for their genuineness to be shown by corresponding accounts from the other side of the earth or the
