”Thus although the Icelanders are still prevailingly light haired, they are darker than any purely Norwegian population in Norway. In Norway black hair is everywhere, except among the Lapps, in a very small minority; in Iceland it rises to the figure of 9 per cent, while red hair accounts for 3 per cent more. The presence of these two colors in such quantities is an excellent indication of the persistance of a strong Irish strain.
This indication is strengthened by a study of Icelandic eye color. The ratio of light- and very light-mixed eyes (Martin #13-16) rises to 76 per cent, as high as the Trøndelagen ratios. But in Trøndelagen the majority are light-mixed eyes (Martin #13-14) while in Iceland, as well as in Ireland,52 over half of all eyes are pure blue.”
