[14] Bertrand, 1876 a and 1876 b, gives a full account of it. The best recent authorities upon Scandinavian culture are Sophus Mueller, 1897, and Montelius, 1895 b. Other works of reference are those of Worsaae, Nilsson, Hildebrand, Madsen and Rygh, full titles being given in our supplementary Bibliography of the Anthropology and Ethnology of Europe. Comprising nearly two thousand titles, it will be provided with a detailed subject index.
