The next records are those by George A. Otis, published in 1876 in the Check List of the Specimens in the Section of Anatomy of the United States Army Medical Museum, Washington (pp. 13-15). Aside from those on Greenland crania the author gives here the measurements of 3 presumably Eskimo skulls collected by Dall; of 2 western Eskimo skulls, no locality; and of 3 Mahlemut skulls, probably from Norton Sound (St. Michael Island). In his later (1880) catalogue,[110] page 13, Otis adds to the above three skulls from Prince William Sound, which, however, were more probably Indian; the three Mahlemuts, on the other hand, are given with the Alaskan Indians (p. 35). These data are of but little value. The Eskimo skulls are the same Smithsonian specimens that were reported upon in 1868 by Jeffries Wyman. In 1878, Rae[111] mentions some measurements or observations on the skulls of Western Eskimo by Flower, but no records of these could be located. Rae says: I had the privilege of attending the series of admirable lectures so ably given by Professor Flower at the Royal College of Surgeons a few weeks ago on the "Comparative Anatomy of Man," from which I derived much useful information and on one point very considerable food for thought. I allude to the wonderful difference in form exhibited between the skulls of the Eskimos from the neighborhood of Bering Strait, and of those inhabiting Greenland, the latter being extremely dolichocephalic, whilst the former are the very opposite--brachycephalic, the natives of the intermediate coast, from the Coppermine River eastward, having mesocephalic heads. In 1879 Lucien Carr, in his "Observations on the Crania from the Santa Barbara Islands, California"[112] (p. 281), gives erroneously Otis's measurements of Aleut skulls as those of "Alaskan Eskimo." Meanwhile W. H. Dall has published (1877) his monograph on the "Tribes of the Extreme Northwest,"[113] in which he includes Wyman's and also some of Otis's data on the Eskimo (and Aleut) skulls from Alaska and Asia. The Tshuktshi are now classed as Asiatic Eskimo, the Mahlemuts as Eskimo from St. Michael Island. The total number of skulls described in the former series is 11, in the latter series 6 (of Aleuts the number of skulls measured is 27 adults and 7 children). The means of the principal measurements of the Eskimo series, both sexes together, are as follows: JEFFRIES WYMAN'S AND OTIS'S MEASUREMENTS OF WESTERN ESKIMO CRANIA
