These results are of course to a great extent conjectural. But it is noteworthy that, of all the writers who have discussed the subject, the majority, and certainly not the least able of them, have expressed their belief in marriages between first cousins being more or less unfavourable to the offspring.[2012] And no evidence which can stand the test of scientific investigation has hitherto been adduced against this view. Some writers have, indeed, cited instances of communities where consanguineous marriages have occurred constantly without any evil effects having appeared. Thus the Pitcairn Island, uninhabited till the year 1790, was at that time peopled by nine white men, and six men and twelve women of Tahiti. In 1800 the population consisted of one man, five women, and nineteen children; and the descendants of these persons are stated by later travellers to be strong and healthy without any traces of degeneration. Omitting whatever else may be said against this case as evidence for the harmlessness of consanguineous marriages, I need only call attention to the facts that, since the colonization of this island, a few strangers have joined the little colony; that it was once removed to Norfolk Island, and that, of those who returned, one was a Norfolk Islander who had married a Pitcairn girl; that the island has frequently been visited by ships with their crews;[2013] and that, as Beechey expressly states, the same restrictions with regard to intermarriage of relations exist here as in England.[2014]
