For purposes of comparison with these three presumably Bushman crania, I have had three other crania at hand from the University Museum, of the genuineness of which there can be little doubt. One of these was presented to the University Museum by the late and much-lamented Dr. W. H. J. Bleek, to whose labours[66] in elucidating the language and rescuing the folklore of the Bushman tribe from perishing we owe so much. This skull, which was brought to England by Mr. Alfred Hughes of St. Asaph, bears a label, “Eland’s Bun, nr. Schintpriten,[67] Bushman’s skull,” and was handed over to me by that gentleman at the desire of Dr. Bleek. A second skull came into my hands through the kindness of W. G. Marshall, Esq. of Colney Hatch, having been entrusted to him by George Dunsterville, Esq., of Port Elizabeth, Algoa Bay, S. Africa, who was for some years surgeon to the hospital at Port Elizabeth. This skull, which, like the preceding, belonged to an exceedingly old man, carries the following labels:--“From the Transvaal, S. African Republic;” “Of an original Bosjesman, a tribe of small Hottentots, now nearly extinct; over age; height, 4 ft. 4 in.” The evidence for the authenticity of the third Bushman cranium which was in the University Museum previously to the arrival of Mr. Oates’s consignment, is even more irrefragable. This cranium was procured for the University through the kindness of H. N. Moseley, Esq., F.R.S., from Mr. Fairclough of Cape Town, and with the cranium came a knife, a poison-pot, a quiver, a poisoned arrow, and an ivory wrist-protector which had belonged to the owner of the skull. This skull belonged to a man past the middle period of life, and is remarkable for its absolute height, no less than 5·⅖ in.; which, however, falls short of its absolute width, which is no less than 5·6 in., by which inferiority the tapeinocephalic or platycephalic character which Mr. Busk (_Journal Ethn. Soc._, London, Jan. 1871) insisted upon as existing in Bushman crania, is preserved in it as well as in the two other crania just specified. Retzius, in a paper first published in Swedish in 1856, subsequently in German in Müller’s _Archiv._ for 1858, and fully republished in the posthumously issued (1864) _Ethnologische Schriften_, p. 149, after saying that he had before him only a single skull of a Hottentot, and the figures which Blumenbach and Sandifort had published of Hottentot and Bushman crania, declares himself unable to detect any essential difference between such skulls and those of true Negroes. His great authority, therefore, should not be quoted to the disfavour of craniological evidence in this or any other similar question, inasmuch as he only speaks, and avowedly, from very scanty materials.
